Hi team,

My customer is developing M0C1104 and they find problem as below.

Duplicate steps:
1.Compiled the “flash_bsl” demo project and generated the flash_bsl.out file.

6.However, since that operation, the device no longer accepts any new firmware uploads — every subsequent attempt fails instantly with the error below:
