TMS320F28377D: In our New board Flash booting getting failed randomly.

Part Number: TMS320F28377D

One of the IC which  shares data bus(D12) solder touch up then issue resolving. How to come out of this issue permannetly.

Hardware wise default status high GPIO72,84 maintained.

Will the Software update in Command file solves the issue.

Please reply recommanded updates in CMD file

  • Intermittent (flash) booting problems are seldom caused by S/W issues. Please probe GPIO72/GPIO84 pins throughout the power-up phase. They should be high and there should be absolutely no glitches until the branch to flash is complete. 

    I am afraid the problem description is very vague. Unless the problem is described more precisely, we may not be able to help effectively.
