Hi,
we are using AM3352 based custom board with nand Micron MT29F4G08ABBFAH4. we were using the 4.14.38 Linux kernel and 2018.01 u-boot since long. board and software works fine here.
And we try to upgrade the Linux kernel to 4.19.20 with same board and u-boot, we are getting omap2-nand 8000000.nand: uncorrectable bit-flips found and that leads to ubi0 error: ubi_io_read [ubi]: error -74 (ECC error) while reading 13 bytes from PEB.
Finally the rootfs mounts ro. Next boot ubi mount, gets failure due the previous ecc errors.

I attached the boot log, please give some input on those errors
I need to know ti-processor-sdk-linux-am335x-evm-06.00.00.07 prebuilt binaries is working with am335x-evm board nand boot?. Here i couldn't verify with our custom board.
