Hi, we are trying to flash with keil mdk bin file and failing when validating user firmware. Below is the output from Tera Term.

It is waiting forever to download new user firmware, didn't have any issues until application firmware modified and being new to keil mdk, not able to figure out why application code changes disrupting memory mapping.
Below is the SCT file

Any help or pointing in the right direction greatly appreciated.
