It looks like the hardware connection error. Please double check with this.

If the error insists, please share what you connection in your board with some picture or simplified schematic diagram.

Hi Shubham,

Two sugegstions here:

1. Could try connect RST to device NRST pin.

2. Please confirm whether PIN1 of your MSPGANG is reversed.

I verified with the MSPGANG board it could work with your firmware version.

If the error persisit, please run the self test and check whether it has error.

B.R.
