LS2088ARDB: How to recover when QSPI Flash is corrupted

I was able to boot LS2088ARDB in QSPI-Boot mode. The QSPI-FLash has some preflashed boot images (bl2_qspi.pbl, RCW, fip.bin).

Accidentally I erased the boot images in QSPI-FLash. Now the board does not boot in QSPI-Boot mode.

I used Lauterbach JTAG - Trace32 and used the script `present at the path C:\T32\demo\arm\hardware\ls208x\ls2088a\ls2088a-rdb\ls2088a_sieve_sram_failsave.cmm

The script does the below

1)override RCW_src=Hardcoded,

2)JTAG Uses the basic RCW present int he script and boots

3)Loads basic app into internal RAM

Question:

1) Can you provide us with a script which will configure clocks and DDR so that we can load U-boot onto RAM.

2) Also please provide steps OR correct me if my recovery steps are not proper.

3) Also in the path C:\T32\demo\arm\flash we dont see flash script for ls2088ardb. Can you please provide if you have it.

Thanks and Regards

NXP only provides CodeWarrior to the customer.

You could refer to section "9.4 Board recovery in case of missing/corrupt RCW in IFC memory" in the attached CodeWarrior document.

Please refer to the attached CodeWarrior initialization file for LS2088ARDB.
