CCS/AM4376: xds510 USB/xds510 USB plus emulator not able to connect with AM437x EVM card.

Hi,

The error indicates the utility is either unable to talk to the Debug Probe or to talk to the target hardware.

For the first case, the usual suspects are the USB ports, USB cable, issues with the Debug Probe itself. Can you test the Debug Probe in another host or see if Windows enumerates it correctly?

If everything seems to be in order, I would double-check if the target board is properly powered or if it does not have pre-loaded code running - sometimes it blocks JTAG access to it. If none of this applies, I would also check if other targets may be connected successfully - it may be a defective board or device.  

I am able to connect to my AM4379 IDK board, therefore there is no fundamental incompatibility, although the use of this particular Debug Probe is not recommended for this device - check this reference.

For your reference, the result of the test connection should indicate the following:

Test Connection said:

Execute the command:

%ccs_base%/emulation/drivers/sdjtag.exe -f %boarddatafile% -v -X reset -X scantest

[Result]

** BoardFilePath: C:\Users\a0356111\AppData\Local\TEXASI~1\CCS\CCSV7_~3\0\0\BrdDat\testBoard.dat

Hope this helps,
