Part Number: MSPM33C321A

Hi team,

One programming vendor is developing tool to flash M33C321A. 

They follow TI document, SLAU962, chap5.3.4.2 as below. While doing ERASE, M33 doesn't reply.

Below is the waveform from the init process. Attachment ALL200_E.zip include the details.

When setting STATCMD, the read register value is “0x00000000”.

    Hi Jerry,

    Please, confirm that the customer is following the existing flash programing examples in the SDK as those work as expected. The most common issue is not acquiring the Flash semaphore from GSC before trying to program the flash.

    Thanks,
