problems when writing data to flash on LS1046ARDB

[uncoldice]

Hi,

I am following the document "QorIQ-SDK-2.0-1702-IC-Rev0.pdf" section " 4.4.8.8 Programming a New U-Boot, RCW and FMan Ucode" to update the RCW on vBank4 on the board.

Below is the steps:

We can see that after sf write, the written data on VBank4 is not same as stored in DDR address 85000000. It seems to have a endian swap issue.

However, if I use below command to copy data from VBank0 to VBank4, there is no problems, all the data OK.

Hello uncoldice chen,

It seems that the RCW file which you used is not swapped, please use SDK 1703 release, the attached is the RCW file from SDK 1703, please refer to my following log.
