Hello! I’m working on some QT5 application intended to use on Colibri T20 board. Recently I faced with UBIFS corruption problem, which occures after random power cut. Following this topic Yaffs2 issue in Colibri T20 I reverted the commit, recompiled kernel and flashed it to the board. But nevertheless I deleted old UBIFS partition invoking the command from UBOOT it still tries to create it or maybe create YAFFS2 one I don’t know. The result is continiously error messages over RS-232 terminal after start flashing procedure. I think I should manually do some additional action before flashing to prepare YAFFS2 partition, but I’m not familiar with that. Please give me step by step guide of what I should do after making SD card with the image. Thanks!

I’m sorry, but the context provided does not contain specific information on creating a YAFFS2 partition for the Colibri T20 or handling file system corruption issues related to power loss. You might need to consult additional resources or documentation specific to YAFFS2 and the Colibri T20 for detailed guidance.

Hi @artem190 ,
As requested over email, please provide the details asked.
Note : Colibri T20 has already an End of life product and no further development is encouraged
Hi! Sorry for my late response, I was in a little vacation. I’ve mailed back recently. My employer had been integrated T20 in their design so I must fix the issue to maintain it stability. I’m just asking for clarification of the procedure described by your colleague Marcel earlier.
Hi @artem190
The Colibri T20 is an really old product (from 2011) and we don’t have software support for it anymore.
You can find some old documentation that could help you here, but not sure if this still applies.
