MSPM0G3507: Migrating from 64 pin to 32 pin

PA10 and PA11 are used in the example

From the datasheet:

PA10 is pin 56 on the 64 pin package and PA11 is pin 57:

On the 32 pin package they are pins 14 and 15.

Hi Krushna,

As Keith mentioned, the pin number on the package will be different from the 64 pin package to the 32 pin package. I'd encourage you to re-check your pins in testing to see if this is the source of the issue.

If this is not the issue. attach a screenshot of your config and program.

This is my sysconfig file and code 


Thanks & regards,

You are using a different UART, so the pins are PA13 and PA14, or pins 17 and 18 on the chip.

Yes I am using different UART on PA13 & PA14 but I am connecting my USB to serial connector correctly on the respective pins.
still the problem is not resolved.

So you are using custom hardware, correct? Is there anything hardware-wise that could be preventing the UART signals from reaching the device pins? If the USB-to-GPIO was working before I'd assume it is still working but you could check that as well. Particularly if your old program is working, and you have correctly switched the pins and device (Sysconfig looks correct), then to me this points to a hardware issue.

Put a scope on it to verify that you are sending and receiving on the correct pins.
