I downloaded the Emac Lwip demo Version 00.03.00 available at
but was unable to run it on my board:
I checked and the debugger selected in the project was XDS 100 v2 and changed it to XDS110 (the one on my TMS570LC4357), but now I am unable to flash (debug) the code as it is giving the following error:
Texas Instruments XDS110 USB Debug Probe_0/CortexR5 : Target must be connected before loading program.
Did you make sure that the target is actually connected? Based on the error message it seems not to be the case.
