content: Hello I have a TDS754D with a FAIL ++ Processor error the board used is a 679-4349-00 version. this is the error i got:-------------------------------------Executing Smalltalk-> ERRORID: 358 nv storage too small more bytes requested than availableExecuting Diagnostics from Menu0x5fffe80 (tRootTask): libError 358, lib EXTCAL, id=358, msg=more bytes requested than available Start Power-On Diag SequencehwAccountant probe routinesProbe for unexpected pending intsnvLibrariansDiag ............... ***FAIL***..error details:ERRORID: 163 diagnostic test failure nvLibrariansDiagLibs with crcc failures:ExtConstI swapped both Dallas chips: (1) NVram chip (1250Y-100) and (2) 1486 RTC Clock chip.After i desoldered the NVram to backup the pins fell off and part of the chip fell off. i tried to export info from the chip but not sure i managed.Other people told me the unit can be used with out the chip, so the chip doesn t be a part of my error.i have FV:v7.4e which is a very late firmware version. i only found 6.x and 7.1.1e version no 7.4e version on the web.i am curious and want advise how to solve my problem.My unit boots up and looks like it is working 100% ok but what is going wrong with: "nvLibrariansDiag" what causes my FAIL ++ Processor error.help wanted

content: Charly, I assume that the error is caused by the scope missing its NVRAM data. Try running an SPC process (signal path comp) first, setting a few options in the scopes user interface before.If that doesnt solve the problem, getting an image from another TEK754D might be another workable approach.But this is just a WAG, so

content: Quote from: SAUL BRITTO on March 12, 2016, 09:07:19 pmThis kind of error could mean anything and is most likely due to uninitialised values in the NVRAM. IMHO the only way is to force the scope through some kind of initialisation procedure OR get an NVRAM image from someone.

content: ok there is something wrong with my NVram but the error is not fixed with a new 1250Y. there are also problems with my DS1486 and i think the options are inside there... uuhh were inside there. so as a matter a fact after today when i did a extended debug logging after that everything was lost... i did the debugging with (switch 6 and 7 dipped).after that booting no options anymore...... strangly................. when i dipped 3 ( this short bootup the unit, no long diag) but the scope starts with all options enabled?? this is bit strange for me.when i run SPC it is passed.Now i am waiting for my new vp390 programmer to arrive. my TOP853 failed... after verifing my DS1250Y !!So after the long debugging today all my CALLs are saying "initializing" and NO options are showed anymore..i did some tests: when i boot my dos computer with GPIB configi can do a clearerr.exe run what clears the errorlog in my scope -> works perfect!-> but i can not read nor write the Nvram or flashrom with the tektool ?? -> doesn t work !i waited for 1 hour and nothing happens ..yes yes i flipped the write protection switch.ok My logging:RUNNING FROM DRAM.DRAM test passed.Bootrom Header Checksum passed.Bootrom Total Checksum passed.BootRom Check Sum passed.Bus Error Timeout test passed.Kernel Diagnostics Complete.Calling SDM (monitor) Routine.Enabling Bus Control register.

content: Not 100% sure, but AFAIK, these Teks have a WriteProtect switch for the NVRAM which can be toggled by poking a stick into a hole in the case.As long as its set to write protect, no access to cal ram.

content: I see a whole lot of unrelated errors. I'd investigate where the thermistor reading is coming from in the hardware and trace it back to the address/data bus. It could be something is wrong with an address or data bus somewhere which causes various subsystems to fail. It can be hard to find the source of this problem!

content: Hi Charlyd. I agree with Saul Britto. Get an good nvram image from someone with that scope. RX8pilot has one close to yours. Maybe you can pm him about that. I only have a TDS-644A scope being my latest model. Have you searched the Tektronics website and forum for help?

content: Hi the image is not the problem i have one but the programmer is since i can get connection with the tektool. ( i am in research for that otherwise i have to wait for arround 2 weeks).but there is more....after dipping arround with the switches 3 and 6,7 Tektronix ACQUISITION Board was also failed.Then i found out there was something with the enabled options. nearly all options were enabled... this is maybe what NCTNICO saw in the logging.-> enabled options which are not present in the unit i assume...because i have some connections on vendor site i got a tool to set and reset options in seconds by commandline tools (sharing is not possible sorry) and found that too many options were enabled. i took my orginal setting -> 13 1F 2F 2C <- from the picture from before the failure and pushed those options in the new DS1486 (timekeeper /options set ) and when i boot up and look into the status now the right options are set ok.-> DS1486 -> new ->OK-> check.!-> DS1250Y -> new -> waiting for tektool or programmer.-> ACQUISITION Board ->PASS-> check-> SPC ->PASS-> voltage ref. -> stillinitialize-> frequentie ref. -> stillinitialize

content: Has someone tried to replace the IC's U1052 and / or U1055 on the ACQ-Board ?I can state that the D-series Scopes have stored the Cal-Constants in these I2C-EEPROMs '24C02' on the ACQ-Board.My TDS540D (the monochrome variant of the 754D) also had a constant fail "FAIL ++ Processor error" on bootup and while self-test.Checked the above stated EEPROMs on mine, to see U1055 was brick dead. As a precaution i replaced both chips.I had preprogrammed the new EEPROMS with images, I belive tinhead had uploaded somewhere here.My Scope has FW v.7.1.1e, tinhead files where taken from TDS754D with FW v.7.2echeersinduzer

content: Quote from: induzer on January 08, 2019, 07:57:00 amYes, I did this some time ago with my TDS580C - resolved some strange error message, can't remember, afair something similar to the OP. Used a known good image from another TDS580, but a complete calibration of the scope should be done anyway, since these cal constants are specific to the particular ACQ board.Another interesting thing: someone else had swapped the CPU board, leading to the scope not knowing itself - showing TDS??? at startup. Updating the FW to a newer version (can't remember) solved this.

I have wired the console port adapter cable and it is a straight cable and I havn't got any comm with the scope. I don't want to hook up a null modem adapter if it will damage anything.
