i did what you told me to do.
First of all can you answer this question would be super helpful

Do i need to change the RCW source to eMMC, hardcoded instead of IFC NAND????????? because I am flashing into the eMMC my customized board does not have NAND flash
I assume you was using 9A, this what I did.
(1)I imported your project
(2) I went to generated code then I changed the pbl.bin to ls1021a-rcw.txt then I load this file from the debug configuration of my OCRAM board project
(3) I used OCRAM init script and memory script then run debug
