UNIFLASH: Question about how UNIFLASH works

Part Number: UNIFLASH
Other Parts Discussed in Thread: TMS320F28374S

Hi,

I have two questions about how UNIFLASH works.

We conducted verification at UNIFLASH. As a result, an error occurred.

1. Does the verify check the entire area? Or does it stop at the address where the "error" is found?

2. When writing to Flash with UNIFLASH, it is written for each sector. Is my perception correct?

Thanks,

    It will stop after the first failure is encountered and reported. There may be more mismatches after that but they will not be detected/reported.

    This may vary depending on the type of flash. What device are you referring to?

    Thanks

    Thank you for the quick response.

    → Is there a way to check the accuracy of the remaining memory values after the first failure?

    → The device is TMS320F28374S.

    One option is to do a memory dump to a binary file to analyze the contents and compare with the expected results.

    Thank you. I will bring this question to the attention of the device exerts

    For 28x, different addresses within the same sector can be written to separately on c28, so a sector doesn’t have to be written to in a single chunk.
