TMS320F28035-Q1: Flash Area Data Error

Part Number: TMS320F28035-Q1

Dear TI experts,

We found that some markets returned to the machine, F28035 FLASH in the BOOT area of some data and addresses are misaligned (the wrong flash area, the front and rear data addresses are correct), we suspect that the chip is burned with the emulator before leaving the factory caused an error, is there such a possibility? Can you help with some analytical ideas? Many thanks!

    Rogers,

    The flash API/flash tools will perform a verify of the contents before completing the flashing process.  My point here is that if there were some mis-programmed areas at time=0 the flash API should have returned an error.

    For devices that you suspect have issues, you should be able to use CCS to run a "verify" operation against the original .out file that was used to program the data to confirm any issue.  Or you can manually save the flash memory to a txt file(memory export/save in CCS) and compare to a good unit.

    Best,

    Matthew
