LS1021A-TWR: Flash programming with CW

[z_v]

Hello,

Upon trying to program a new u-boot with Code Warrior I got the following messages:

fl::target -lc "LC for Simple Flash"

Hi Adrian,

I double checked.

SW2,3 are set to bank 0.

Thank you,

If the switches are correct, then try to unprotect before erase/program.

Hi Adrian,

I recreated the CW RAM application project.

Now programming works fine.

Thank you !

From the dip-sw make sure the IFC is enabled and QSPI is disabled.
