MSP-EXP430F5529LP: Unable to connect to the fresh board

Hi Charles,

According to the error message, here are two relevant posts for your reference, hope it would be helpful to the customer.

MSP430FR5969: MSP430: Error initializing emulator: One of the connected MSP-FETs / eZ-FETs debuggers needs recovery

MSP-FET: One of the connected MSP-FETs / eZ-FETs debuggers needs recovery

Best Regards,

Hi Experts,

  I have a customer who just received a fresh MSP-EXP430F5529LP. When he tried to upload a new firmware using Uniflash, he will get a error message like below. In Windows Device Manager, the USB port does not seem to enumerate successfully as there is nothing shown up. How do proceed from here? If the firmware for the debug probe (MSP430-U1) is corrupted, how to reload the firmware? Hope this is not something the customer has to go through with a brand new board. 

"One of the connected MSP-FETs / eZ-FETs debuggers needs recovery"

If LP eZ-FET master (5528) is bricked without possibility to self recover by TI tools, than eZ-FET firmware can be flashed on LP target device (5529) by USB BSL, and than LP target device (5529) can be used as SBW master to flash LP master (5528) with the same eZ-FET firmware that should be automatically updated to last dll version by TI software later. At the end USB BSL can be flashed back to LP target (5529) to factory state.
