LS1020 uboot from QSPI-Flash

[lizboxy]

Used LS1020 boot from SD card.

Now new PCB of LS1020 is boot from QSPI-Flash, so how to deal with  the RCW?

And now, connecting to the CodeWarrior TAP，and got the fail information as:

Failed to resume target process.
CCSProtocolPlugin : CCS: Scan timeout

So, how to handle it?Any advise,TKs!

Processor will be able to successfully complete its POR sequence only if valid RCW will be provided.

For new board there are two possibilities for initial programming:

1) set cfg_rcw_src to a hard-coded option described in the QorIQ LS1021A Reference Manual, 4.4.6.2 Hard-coded RCW options.

2) use CodeWarrior RCW override technique described in the CodeWarrior for ARMv7 Targeting Manual, 8.2 Using a JTAG configuration file to override RCW (see attached picture)
