I connected my custom c2000 320f28335 mcu board via sci_a with com port to simulink for xcp debugging, but there is time out error on connection.
Is there any specific hardware configuration?
matlab version 2022b.
the error is :
Could not connect to target application: XCP internal error: timeout expired, in response to XCP CONNECT command

in my case the problem was due to Gnd connection of board and USB to TTL device, I had not connected Gnd,
after I connect it, external mode works correctly
