To select QuadSPI as RCW source it is needed to configure cfg_rcw_src[0:8] (multiplexed on {IFC_AD[8:15], IFC_CLE}) as 0_0100_010x - refer to the QorIQ LS1021A Reference Manual, 4.4.5.1 Reset configuration word (RCW) source.

There are two options:

1) boot the LS1021A-based board from SD card into U-Boot, then program the flash

The SD card image is available here:

https://lsdk.github.io/components.html

section LSDK IMAGES, select LSDK version 2004

2) using CodeWarrior TAP and CodeWarrior flash programmer connect to the LS1021A-based board and program composite firmware image.

For the composite image please refer to the LSDK Documentation:
