MM912H634 Microcontroller
While flashing the program using Cyclone Pro and PC utility called “PROG12Z_CYCLONEPRO Programmer”
Step 1: Reset / Connect (Enter BDM mode)
Step 2: Erase DFlash
Step 3: Erase PFlash
Step 4: Program the (BL + APP combined) .s19 file
Here during Step 4, While the program is getting flashed, if there is some error (sometimes due to loose connection/handhold), and programming halted, then there is NO further communication is possible with the ECU. ECU is unusable thereafter.
If I try to execute Step 1. Then it throws an error: “Can not enter background mode”.
Appreciate any suggestions / solution
Hello,
Since you use PE Micro programmer and Cyclone PRO, I would recommend contacting PE Micro support.
They should provide more information about the error message.
Have you tried the PE Micro UNSECURE12 utility?
