[U-Boot] Saving u-boot environment on LS1046ardb QSPI bricks flash memory

Hi there,

I am currently working with a LS1046ardb development board from NXP/Layerscape. Using their provided firmware image from the primary QSPI memory bank, I have tried to flash my own compiled u-boot (using the ls1046ardb_qspi_defconfig file) onto the alternate memory bank. I have also flashed a Reset Configuration Word (RCW) which was provided by NXP.

This process is successful and the alternate bank boots into u-boot. However, I discovered that after simply executing a "saveenv" command and then rebooting again into the alternate bank, the alternate flash memory seems to be "bricked". I can no longer boot into the alternate bank and instead, the board will boot into the default bank.

I am wondering if this issue and has been noticed already by someone or if there is something I am not doing correctly.

Is their a specific denx RCW that I should use instead, rather than the one provided by NXP?

Any help would be greatly appreciated!
