iMX6DL Booting from Nand

[JackLEE_]

Hi community,

I am working on custom board based on i.MX6DL sabreSD.

I have success with boot from SD card and now I want to boot from Nand flash(MX30LF4G18AC).

However, after burning the image to Nand, i get the error "ubi_io_read: error -74 (ECC error) while reading 126976 bytes from PEB 4:4096, read 126976 bytes" which can be seen in first boot log. Then, I reboot the board (second boot log), it just jump into kernel panic.

How to fix this error?

Any advice would be grateful.

Hello,

The error -74 is related to the issue filed in MTD (Memory Technology Devices).

Please check the following link and verify if you used the ubiformat to flash the image to NAND, you need to enable the “-space-fixeup”

Best regards.
