Dear Sir/Mrs.

We are MCU Programmer developer and supplier.

During our developing for MSPM0Lxx Chips, we foud that once we write data(this data is disorder, just for testing, not arm instructions) to chip flash, after poweron, SWD couldn't be entered, it response the Fault ACK after reset is release. How could we to re-connect the chip by SWD?

Best regards,

Alan

Hi,

The chip can not be re-connected. As your NON-MAIN is changed

No, we do not modify any data for NONMAIN.

first chips we try is using JFLAH, after programming thr flash, and when we re-connect to JFlash (Ver 7.88K), it reports error, and then I capture the SWD waveform. and found taht Fault is return after read JTAGID and do JTAG Powe Up, read DHCSR is return 0.

just onment, I try to use AP=2 to connect the chip, it no any Fault ACK even reset has been released. but seems that read any register it returns 0.

Best regards,

Alan

Hi,

Can you do a factory reset with XDS110?
