Good day TI Team,

Please guide us to recover LP-CC2340R5 and to continue programming other examples.

Details:

While trying to load the example - simplelink_lowpower_f3_sdk_9_12_00_19\examples\nortos\LP_EM_CC2340R5\mcuboot\mcubootblinky

into LP-CC2340R5 using the below connection

We are getting the error in below sequence:

1. Target not connected
2. During next try getting error - 1274 @ 0x0

We tried two boards; both the boards are not working now.

It looks this example corrupt the boot area of MCU.

So that not able to program after try to programming this example.

Please guide us to recover the board LP-CC2340R5 and to program the other example.
