Dears,

The EVM board can not connect the uniflash and ccs after loaded oad demo, and can not load new firmware, the CCS and uniflash always report Error -261.

Please provide SimpleLink F3 SDK and Uniflash versions, OAD project used, and LP-EM-CC2340R5 board and CC2340R5 device revisions. Error -261 indicates a communication issue between the computer and the XDS110, not the XDS110 and the CC2340R5 device. Are you able to program and debug inside of Code Composer Studio? Please disconnect all hardware/tools, reconnect, refresh the Uniflash session, and try again.

Regards,
Ryan

Thanks, these versions are suitable and you must still determine the cause for instability between the LP-XDS110ET and PC. If you have any other LP boards or computers available then please test these as well.

Regards,
Ryan
