Due to unstable working Debian 8.5 and kernel 4.6.2 (eMMC chip read and write errors, files disappearing) I’m trying to move from ext3 to ext4 using Apalis_T30_LinuxImageV2.6. First question, is it possible to make that kind of migration using Apalis_T30_LinuxImageV2.6? Bellow you can find diff, with steps which I have already made into Apalis T30 Linux image to swap from ext3 to ext4.
Could you correct me if am I on the good way with migrating to ext4? First problem occurs with cp_file_chunk variable. Even though I changed this variable in flash_blk.scr and flash_eth.scr files, I need to set it up again just after running command run setupdate. After this change image is deploying, but problem occurs as bellow:
I don’t think the instabilities you are seeing have anything to do with the file system used but rather with it either using background operation certain eMMC chips like the ones from SKHynix do not play nice with (e.g. due to their firmware being terribly broken) and/or using HS200 mode our hardware may not be compliant with. While nowadays I agree using ext4 would be the preferred choice unfortunately this was not yet stable in the down stream Linux kernel our official BSP uses which is why our flashing/update infrastructure so far utilises ext3. That said changing from ext3 to ext4 should be rather trivial to do. More information about the eMMC thematic can be found in the previous thread about running mainline on Apalis T30.
I have applied patch from this link. Linux works far better apart from when, I’m trying to install lxde or xorg only, I’m getting into big trouble. Just after xorg installation and system reboot I’m flooded with messages on me debug console:
