content: Doesn't look bad. I haven't worked with NXP MCUs so far, so I can't make a specific comment.But certainly I could see some applications. For instance, it looks beefy enough to be able to run some pretty nice audio effects/synthesizers while being a lot cheaper than the usual DSPs commonly used for that (especially for the dev tools!)

content: I find the new RT1024 more interesting, it is like the RT1020 (Cortex M7, 500Mhz) but with internal flash memory (4MB), and in LQFP144 format to be able to make designs with greater comfort.One of these days I will try to make my first design with BGA, something that has a large pitch (0.8mm, 1mm), but still requires a 4 layer PCB which is quite expensive.The only thing that caught my attention about the RT1070 is that it incorporates 2 and 4 lanes MIPI, interesting to be able to make designs with video screens, it remains to be seen if it supports hardware JPEG decoding. I already saw the datasheet and it seems that no, a pity, for now the only microcontroller I know with MIPI-DSI and hardware JPEG decoder is the STM32F769 / 779.

The teensy series is the de-facto dev board for some of the NXP MCUs, but they don't bring out all the pins conveniently, nor do they have a debug interface.

Also added a current monitor, a FTDI converter, 32 KHz osc and a few other things. Have helped me a lot on some of my designs where I needed to check some stuff before doing the final design....I will do the same on the 1170 once that arrives.

content: Quote from: mac.6 on December 28, 2020, 08:25:45 pmYeah, not the same approach at all though. The RT600 is an hybrid with a Cortex M33 core and a DSP core (completely different) from Cadence, this arrangement makes it a lot less convenient to develop for. And I also don't know how efficient this DSP @600 MHz is compared to a Cortex M7 @1 GHz with the proper extensions. OTOH, it seems cheaper. Overall, not what I would be looking for personally.

content: Quote from: luiHS on December 28, 2020, 08:20:43 amJust a couple thoughts. 4-layer PCBs are not that expensive anymore. Besides, for high-speed digital logic, I would certainly avoid using anything below 4 layers anyway.And then, relative to BGAs in particular, the additional cost is not just PCBs. Unless your PCBs are huge, I guess the added cost will even be marginal compared to the additional equipment (and training) you will need to properly solder BGAs. Not that you'll have to spend a lot either, but if all you have is soldering iron, then you'll need to invest in some additional tools and learn how to use them.

content: No reason not to get 4-layer boards anymore, and I only use 2 layers for adapters, test fixtures, and the simplest boards anymore. Simply having fixed power and ground planes available almost anywhere is well worth the small incremental price. They also have friendly design rules, so makes layout easier in many ways.A large 0.5 pitch BGA on the other hand will almost certainly call for plugged blind vias with close to zero annulars (or microvias), which will begin to cost real money. The usual CN prototype line ±2 mil drill precision just isn't going to cut it, and they won't do blind vias at all.I haven't looked at the M7 or its cache implementations (which I assume is part of the ARM core), but for DSP it should probably be disabled, or if it's possible peg a portion to it to always map to an address range so it can be used as a fast buffer. Otherwise it's not going to be any faster than the SRAM used. (And in fact a normal associative cache will only get in the way and make it difficult to validate performance; so it gets disabled, and then if enabled the speed benefit is of no value since it can't be relied on.) But if it's peggable, or some coloring scheme can be used, then that 800M/1GHz might make a difference!

content: - It has 2MB of RAM, which is plenty for many applications.- Processing power and available memory address two different needs.- This is still a microcontroller, not a complex SOC made for mobile phones. It's easier to use, draws less power, has more peripherals, lower latency, etc.- It has an SDRAM controller for more memory if required.Cortex-A-based CPUs/SOCs target a completely different market, and they often come with annoying licensing issues, difficult and/or costly access to SDKs, etc.This reminds me of another thread dealing with the idea of 1GHz+ MCUs. Apparently, 1GHz looks like some psychological threshold to some.

There are the SiFive MCUs, then a couple chinese companies (like GD) also offer RISC-V MCUs, then there is the Kendryte K210. You could start a dedicated thread for that BTW, in which people could list available off-the-shelf RISC-V CPUs/MCUs.

content: Its pretty much the same as "you will never need more than 640 KByte"Seriously, it has 2 MByte SRAM inside, soon there will be a version with on-chip Flash memory (like the 1064), then you have a standalone CPU with 2 MByte of SRAM and (probably) 16 MByte of Flash. You only need a 4.7 uH inductor, two handfull of caps and a couple of resistors, and off you go!At that is with a chip in the $10..$12 range !

Not that it matter that much, its easy to have the flash sitting outside when its only a few pins (6 in total) that needs to be connected.The Errata sheet is available, there is the "usual" stuff on M7 core and few NXP ones, not much worse that what we have been used to on NXP devices.Interesting with the H7 and lifetime, I was not aware of that one, currently (soon) looking into the H747 for a possible project, thanks for the headsup!Regarding HASL, I wouldguessthat it could work if the HASL is very level, personally I always get ENIG on all I do, even simple 4 layer boards, I like gold

They really stole my - or rather my boss' - soul with their "value" series.And I would really like to try out some other producers' inventions.Those Mbs of flash on nxp device definitely will be expensive.

content: Quote from: cgroen on January 03, 2021, 09:16:20 pmYes, but I'd point out that an on-chip (or off-chip) QSPI flash is not going to be super-high performance and the internal flash in an H7 should run circles around it. I'd think so at least. I admit that maybe 80% of the time QSPI would be good enough as to have negligible impact. It is definitely impacts my work, at least, and the issue would make my short list. There does seem to be a real lack of I/O bandwidth in the on-chip QSPI flash case given all the horsepower in the core, IMO. (Of course there are things you can do e.g., copy to an external SDRAM but I'd rather not for cost and power reasons).On the other hand, RT1170 has HyperBus options while only a few H7s do (which happen to not be the models I'm working with now) which may close the gap or more, depending.

content: Quote from: bugnate on January 04, 2021, 12:56:26 amThe first thing you do is copy the part you need to RAM. There are some complications here though, in particular you don't want PIC binaries, so the binary needs to have a portion designed to execute relocated to the external flash, copy the first small piece to RAM, like 128 bytes or something, and jump to it; this prologue then copies the rest into RAM. The parts running out of RAM need to be properly linked to do so, which means somewhat overly complex linker scripts to combine multiple relocations into a single flash binary. And, the code needs to get addresses from the linker so it knows what the section sizes are for the copy. If the flash also has pieces that don't need copying, such as rarely accessed data and various strings and such, then it's even more complicated (especially if the data is organized in any kind of pointer based graph like a tree). It's not super complicated, just... unnecessary.

content: Quote from: Marco on January 04, 2021, 12:54:24 amThat's just excessively opiniated and neither true not that well thought out. If you don't need the speed of LPDDR RAM (and data size, as LPDDR4 chips typically come in relatively large data sizes), you can certainly use SDRAM. SDRAM controllers are significantly simpler, themselves draw less power, and SDRAM is still developed, and available in low-power versions, such as this:https://www.winbond.com/hq/product/mobile-dram/low-power-sdr-sdram/?__locale=enLooking at the datasheets, you can see that their typical power draw is favorable compared to typical LPDDR4.As to cost, the product linked above is about $2.5 for a 512Mbits chip (Digikey pricing, so not the best). The cheapest LPDDR4 chip you can find (again Digikey source, for comparison) is $3, but zero stock, and likely hard to find anywhere else as well unless you are a big customer. The cheapest in stock part is about $10 (yes with much larger 4Gbits, but if you don't need that much memory, that's just more expensive and useless.) Just to give an idea of the situation.Now that was just to explain why SDRAM was possibly not a bad choice here, for again what is still a MCU, and if you're still stuck on the idea that it is shit, you can always contact NXP.

It survived 1 hour and then it went out againNow, to be fair, I did maybe not have enough time with it, but I simply just hate tools that creates zillions of files, and I also hate the fact that it seems to be centered around MCUExpresso IDE (at least that was how it looked to me). I don't use MCUEXpresso IDE, to be honest, I hate it. I use Keil and have been doing that for almost 30 years now, first years the 8051 and since 20 years the ARM version, so that might play a big role in thatLVGL is not too bad to work with without a "builder", its pretty clever how you position controls dependent on other controls, you don't have to use absolute coordinates etc.

content: I would highly suggest that you share your gerbers with them for a proper quote. Also ask on how you can reduce your costs.For a small comparison, our ice40ul1k wlcsp design that is about the size of a 8 pin dip (intentionally), we paid around $0.60 usd each in 1k pieces. This design has via in pad; 4L that were laser drilled. Many shops including Suntak turned us down on this complexity. We work with 5+ shops in China due to assorted capabilities. Often the online quick cart shops are too restrictive with their capabilities.We have also used and met with Kingford PCB in Shenzhen with excellent quality. They build for AMD and others. They are medical certified. We have a number of FDA designs that we supply to Foxconn and others for box builds.You can see our pcb from Fast Turns in the FPGA forum and search for ice40 keyword.

content: Hi. Here are some details and contacts of vendors we have used. For the referenced ICE40UL1K PCB, we designed for a 50-up panel shape due to the very small product. Our Yamaha SMT machine needs the proper panel size to allow for the automated assembly so we used 50-up with edge strips to shuttle in the PCB from the Erka SMT printer.The best quality are from upper tier PCB manufacturers. But please note that they will not deal direct unless you are a large player. For example, Suntak turned down our business of a projected $500k USD per year purchasing. They said the volume is too low for them to take on the business as a direct account.Enter the quality brokers which we usually frown upon but found an excellent contact (Terry) - see below. They work with the factory of your choice and have beaten the pricing we used to receive from Suntak when we were direct with them before they became a public firm.

And as far as I got it, the libraries are Arduino libraries, so available if you're using Arduino with the Teensy. Supports up to Teensy 4.1.I'm more interested in programming it in C, "baremetal". I downloaded the docs and SDK from NXP, and ordered a Teensy 4.1. I'm going to see what is possible with it.

Downside is, the board itself has some kind of high-density connectors and requires either using their dev motherboard, or designing your own.The whole kit is 199€. Clearly not in the same league as the Teensy boards...

content: There is a need for simple devboards. NXP's Dev board is over-featured and not generic enough. ST seems to get it, literally every subfamily has a nuclio board. And the embedded artists board is (1) EXPENSIVE (I don't even know if I'm interested, but she wants a ring), (2), the carrier board at least, irritating to interface. The teensy formula is a winner here, other than JTAG/SWD they have the best form factor.

content: Quote from: tmadness on March 23, 2021, 04:50:51 amI do wish Embedded Artists would of stuck with their DDR2 form factor for the 1170 like the 1052/1062 ones. I've got a small carrier board designed and build already for the 1062 module and it works great. A respin based on the high density connectors wouldn't be too bad, but it'd of been nice if they'd stuck with the DDR2 slot. I imagine there was a reason, but looks like I'm sticking with the 1062 for a while now (besides, for my work it's plenty powerful enough).

content: Quote from: tmadness on March 23, 2021, 04:50:51 amAgreed. Nucleo boards are great for that. No gadgets, cheap, and most IOs broken out. As I remember, TI did something similar with their MSP430 and MSP432 MCUs.Teensy boards are almost that, but most of them have very few IOs broken out... The Teensy 4.1 has more and is great, but still, that's few IOs.Buf when we say "there is a need", is this significant enough that vendors would bother? A few of us want boards like this, but I have witnessed countless times that even seasoned engineers tend to favor fancy boards with a lot of buttons and displays even when they actually don't need them or will use something completely different in the end. I dunno. Maybe it's just the kid that's still within us. Another factor is that engineers buying dev boards in the context of their employed jobs will tend to favor expensive stuff, as long as their management is OK with that, because it's not their own money. Conversely, engineers buying cheap devopment tools, even if those are perfectly fit for what they need, may sometimes face their management's opinion, like "are you sure? a $20 dev board? must be a toy!"

content: I know, maybe I have a "Hack it together" mentality for prototypes, most career engineers want that over featured board when going through their employer. But I've experienced how this reverse mentality of buy the expensive dev board go south so many times. There are too many unknowns, I trust NXP but not all their products are equal. Some of their products may not meet me at the level I want, the support could be iffy etc. Give me any opportunity to buy your product in a generic usable form. If I like it you will hear back from me.

They have been that for the past several weeks, but I get updates from them that my order is postponed because they are NOT on stock, so far the delivery time is pushed to week 17 (did move from week 15 to 17 in the last 2 mails from them)I have asked their customer "support" whats up with that, they have promised me every time to get back, nothing heardSo far, I'm satisfied with my board from Mouser
