No MTP, work well for me I don't have any bugs right now... Eureka is a better kernel, more improvements, better performance... Do a backup of SD, format it and recover it. You will finish sooner!
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] Elmarigo:
I formatted the SD card about 20 times with all the different filesystems. But it will onyl work right with FAT32.ll the others don't work at all or are just read-only.

There has to be a reason why MTP only is working for me with the physwizz kernel, but not with Eureka.

Which OS are you using? I have ResurrectionRemix GSI by RobotHanzo.
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] alexnonim:
Right now I'm testing ALT+F4 Rom and it's working well, maybe the rom?
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] Elmarigo:
If I only I knew wheter a problem resulted from AOSP, from RR, from the GSI implentation, from the kernel.. or whatever :) It's always so spread out.

But at this moment I could fix the SD-card Problem:

In the RR-GSI-thread @eremitein told me to set SELinux to permissive (setenforce 0) and I can write the sd card even with f2fs now, with both kernels :) So this was a Rom thing ( I gues SELinux in general is..)

So, only the MTP problem remains, which is said to be fixed by using a custom device kernel in the ROMs's thread, hmhmhm..

But at least I can now use my phone!

Eureka R7.5 update

​

Changelog:

→ All previous features of Eureka which A40 missed.

→ Upstream Linux Kernel Version from 4.4.270 to 4.4.277

→ Enabled back 208 MHz frequency for big and little cores.

→ DTB is now used to customize Eureka features such as CPU and GPU frequencies.

→ DTBO is only used to disable dm-verity as from now.

→ Added a new flashlight control driver which will be used on AOSP/LOS based ROMs. It will also fix low flashlight issue on GSIs. This new driver does not interfere with camera (which was causing dark photos for some A20 users) Footej camera app is recommended for custom roms.

→ Imported latest Samsung updates from A305F R kernel source.

→ "Samsung A10 1.2A input charging current" feature still depends on Eureka dtbo. Will fix it on next update

→ Fixed wrongly set GPU throttling frequencies.

→ Updated WireGuard vpn driver to latest version - v1.0.20210606

→ Some other minor optimizations.

Hi, this kernel does not seem to work on my Samsung Galaxy A40 SM-A405FN. I tried this with multiple ROMs including the stock one. I get stuck on a black screen after the Samsung logo is shown. The other kernel that is on this forum, the physwizz_kernel.

By the way for users who are stuck on this black screen you need to hold down

'Vol UP + Vol DOWN + Power button' for about 7 seconds, then release the 'Vol DOWN' button but keep holding 'Vol UP + Power button' until you see the samsung logo, this will get you into recovery.

Eureka R8.0 update

​

Changelog:

→ Upstream Linux Kernel Version from 4.4.277 to 4.4.288

→ Added BFQ and ZEN v2 I/O schedulers.

→ Added a new backlight brightness controller. [Feature can be used when new EKM app is released] [Experimental]

→ "Samsung A10 1.2A input charging current" feature has been hardcoded in kernel.

→ Nuked CPU quiet and reverted back to Exynos Hotplug. It should fix issue of cores randomly turning off.

→ Fixed GPU frequency being limited to 1100 MHz after being throttled (v2.0).

→ Some optimizations for better FS performance for EXT4 file-system.

→ Fixed non-detection of some gamepad controllers (such as chinese ones).

→ Patched kernel for android 12 (S).

→ Fixed all remaining warnings in kernel source.

→ For permissive selinux, selinux can be switched to enforcing after boot.

→ Built with Vortex Clang & LTO which is based on the latest version of Clang 14 (20220201).

→ Two kernel versions with different schedulers are now available:

→ Implemented EMS (Exynos Mobile Scheduler) which is a scheduler based on EAS (Energy Aware Scheduling).​

→ The normal kernel version has the stock HMP (Heterogeneous Multi-Processing) scheduler.​

​

→ Eureka kernel R9.0 heavily depends on DTB (not DTBO) for the following features:

→ CPU and GPU overclock & underclock

→ SELinux state (enforcing or permissive)

→ Sound driver compatibility (AOSP, OneUI2 or OneUI3)

→ Energy model and parameters for EMS kernels

→ EMS kernel works best with schedutil based governors. The following governors were added:

Hello i've tryed to install different versions of eureka 9.2 with the last version of cRdroid rom built in february but always crash, which version should i try?

thanks
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] Elmarigo:
Hello @Chatur27

I just updated my A40 with RR-GSI (February 2022) from Eureka 6.5 to Eureka 9.2 But since then it crashes during booting or within a few minutes after the boot. So I sometimes can see the UI and then it reboots, sometimes it get's already stuck with the RR logo and then reboots. Each time when it runs for a few minutes, before rebooting, then SD card cannot be accessed and the camera does not work.

In between I have factory reset the phone, manually wiped all partitions besides system and it won't get better. (I tried permissive and enforcing modes as as dtb stable v1 and v2)

Do you have an idea why?
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] netterhamma:
I have the same problem (SM-A405FN)
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] Elmarigo:
OK, I got it running by installing the previous version (9.0). There's an GSI version inside, which doesn't exist in 9.2.

Previously I thought AOSP/Eureka and GSI where all the same kernel, because this wasn't made clear from the thread. (It sounded more like the opposite). Btw I had to use the stableV1 dtb on my A40, the default isn't stable.

Now I wonder: Will there be no new kernel for GSI? Because the thread only said there wouldn't be a new kernel for OneUI, but GSI wasn't mentioned.

Anyway: Thank you very much for ongoing support, Chatur! :)
[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] Elmarigo:
Hello!

I still have one problem:

My phone sometimes crashes with current Eureka kernel. I think it's because of CPU frequencies. I tried limiting minimum and maximum frequencies for big and little in 'TK Manager', but the manager won't save the settings..

New Update of our Eureka Kernel and there OFFICIAL FEATURES for version R10

Downloads at our Telegram Channel (find on the first Post!)

Modifications to sLMK driver and its configs, to avoid LMK killing every app, but kill based on Linux kernel's task priority. Idle RAM usage decreased, multitasking improved.

Fix an old bug of Eureka Kernel, kernel panic if USB debugging is on, and the phone is connected to PC, and the user tries MTP mode. The fix was inspired by exynos9820 (Linux 4.14) usb driver.

Update Simple LMK driver to latest commit. Includes various memory and driver itself optimizations.

Upstream cfq I/O scheduler, F2FS driver in kernel

Enable misc configs for NetHunter support. (E.g. mac80211, Sysvpic, USBconfigfs drivers...)

Merge upstream patches for USB configfs HID driver. Used for NetHunter.

Misc improvments, hacks applied kernel tree wide

Rewrote mbcache driver - May be misc improvements in I/O operations on ext4 fs

Revert LZ4 driver changes

Adjust TCP Westwood parameters for better internet speed

/proc/kmsg is now toggleable. Use this command to control kmsg buffer:

# echo 1 or 0 > /sys/module/printk/parameters/enabled

PixelExperience_a40-12.1-20220819-1754-UNOFFICIAL as my preferred ROM for A40, flashed via TWRP but without any further things, like no MAGISK etc. to have stock Pixel experience.

Now I read about this updated kernel. Is this already included in my ROM or do I need to install it separately via TWRP? And does it keep my personal user data then? Do I need to install additional things like MAGISK or just installing the updated EUREKA kernel is enough to profit from better responsiveness?

SDIO is used most often in reference to a input/output device, i.e. a wireless card, interface card, network card, etc. Memory is usually just called SD or SDHC depending on the sizes.
