We use TI's MSP-GANG-PROGRAMER.
Now there is a problem. I'd like to ask you for a solution.
Target is FR69721 powered by external 2.4V.
This is the schematic drawing for the connection on our board
One device will succeed, but multiple devices will all fail
Please advise.
I was monitoring the power supply voltage but there was no weird change.
By the way, TDIO has the following waveform and programming result , can you understand anything?
The yellow waveform is target 1, and the blue waveform is target 2.
The power supply voltage is 2.4V due to the circuit configuration.
Also , only one may succeed.
When target 1 succeeds, the yellow and blue waveforms are swapped.
Is there another approach?
Best regards.
I have try the SBW my side with two devices(msp430fr5969) and works good.
Does any warnings appear when the failure happen?There should be some detail description with the failure.
Could you try some blank device(have not programmed before) to see if it is affected by your application code.
Best regards
Gary
