MSPM0L1105: Unable to successfully switch to bank0 after executing SWD initial?

Part Number: MSPM0L1105
Other Parts Discussed in Thread: LP-MSPM0L1306

Dear Experts,

 

I need your help to solve the following problems.

 

The IDCODE value 0x6BA02477 can be read, but it cannot be successfully switched to bank0 after executing SWD initial (write 0x000000F0 to DP SELECT, and the value of AP IDR read is 0x00000000), and the J-Link connection cannot also be successful.

 

The picture below shows the waveform of MSPM0L1105TRHBR. The value read is 0x00000000.

However, using the same hardware and executing the same software on MSPM0G3507SRHBR can switch successfully, and the value is 0x84770001, as shown below.

The circuit diagram of the hardware we use is as shown below.

Thank you and Best Regards,

David
