i have one 21489-ezkit.
with a blocked_based_audio_loop ldr, it works fine for paralle flash programming and boot.
But when I tried to download the ldr to spi flash, it failed with following error:
Error: Failed erasing affected sectors.
if I select "no erase", "write failed" error occurs.
btw, I set the ldr option to spi flash. this should only affect booting issue not programming issue.
For sw3 setting, i set it all On. for sw4 setting, i tried both "booting from parallel flash" and "spi flash". neither works.
can anyone help if my SW setting is correct? or this is a hardware issue?
