AWR1642: AWR1642 Flash burn issue

Part Number: AWR1642
Other Parts Discussed in Thread: UNIFLASH,

Hi,

Originally, we burned Flash chip through UniFlash + AWR1642 + Flash chip, including BootLoader + APP.The burn and write interface is shown in the following figure. After burn and write, the program runs normally and BootLoader updates normally.

Now we want to burn files through Flash burner,

First read the Flash file through the burner, then burn the file into a new Flash, and finally weld it to the circuit board,

However, it is abnormal for Flash program to start. BootLoader can run but cannot update the program, and app cannot start up.

Please help to find the cause of the problem and confirm whether it is feasible to burn Flash directly.

It has been confirmed that the burner burn file is correct.

Thanks!
