I compiled LinuxImage2.8 with QT5 (angstrom-qt5-x11-image) for ColibriT20 and is working, only problem is that the ubifs is practically always corrupted after a power cut.
As said in this post LinuxImage 2.3 seems to work well after a loss of power, so I tried to compile image 2.3 with Qt5. Unfortunately, after many attempts (weeks trying to make the system compile well) I couldn’t do it.
Another alternative that I found possible as it says here and here is to revert this commit in the branch tegra of the Linux kernel repo, and with this, yaffs are used again as in image 2.3.
These are my complete steps:
-
Compile angstrom-qt5-x11-image succesfull and running in my Colibri T20.
-
Then I followed exactly this instructions to build linux kernel for Colibri T20, Summarizing this step:
wget -c https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/arm-linux-gnueabihf/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz tar xvf gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz ln -s gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf gcc-linaro export ARCH=arm export PATH=~/gcc-linaro/bin/:$PATH export CROSS_COMPILE=arm-linux-gnueabihf- git clone -b tegra git://git.toradex.com/linux-toradex.git cd linux-toradex git revert 834b98d0367931d6bec5a48fe87fddd9b877f688 make colibri_t20_defconfig make -j3 zImage 2>&1 | tee build.log
Kernel compiled succeced.
So the I update the kernel, I prepared my sd with my compiled Colibri-T20_Qt5-X11-Image_2.8b6-20191128 image, and from the u-boot command line:
run setupdate
run prepare_ubi
run update_kernel
Finally, when kernel starts, an error occurs (I put only the last part because the first part is repeated many times):

Finally, I so frustrated… could you tell me if this option is valid (reverting that commit in kernel to make the system powercut tolerant) and in that case what am I doing wrong?
Please, I’m trying really hard to solve this issue, thanks!
