2017.x Zynq-7000 - Embedded Linux: UBI ECC error on S34ML02G1

描述

The UBI read command is failing the S34ML02G1 flash on Zynq-7000 with the following error:

[    1.637859] ubi0 warning: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read only 64 bytes, retry

In Linux, there is an issue with the ECC code stored in the OOB area.

U-boot appears to be using the correct number of bytes for ECC, 12 bytes in position 52-63 of the OOB section, however Linux only uses 3 bytes in position 52-54.

 

解决方案

The attached patch will resolve this issue.
