CCS/TMS320F2812: Device locked during watchdog timer programming

Kruthi N K

Part Number: TMS320F2812

Tool/software: Code Composer Studio

Dear Sir,

Before a week back we got this command

C28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.

Later we changed controller then it started working.

Again after loading watch dog program we are facing the same issue. "Device got locked".

Please reply.

Regards,

Kruthi

Hi Kruthi,

Can you check whether CSM passwords are programmed in your code?

It seems the .out you are loading onto your device may be programming the CSM passwords or some CSM memory.
