Linux/TCIEVMK2X: UBI ECC error

Part Number: TCIEVMK2X

Tool/software: Linux

We just got two tci6638 EVM, both it new. Time to time we see NAND ECC errors, like this:

root@keystone-evm:~# [ 4458.912270] UBI warning: ubi_io_read: error -74 (ECC error) while reading 2245 bytes from PEB 301:38232, read only 2245 bytes, retry

On the both kits with the stock software images, without any changes:
