Hi, all staffs:

I erased Flash Sector1 (4Kbytes) using HDFlash IAP C-Driver v1.0 provided by ST, and succeed. But it failed to Sector2 (24Kbytes) when I used the same driver. Both of sector 1 and 2 were erased, but ECMD(0xff) haven't return correct value (0x00) when sector 2 had been erased. Why?

Thanks

Hi,

This problem had been solved. Originally I used one 'for' loop statement to erase both two sectors (1 and 2) one by one and the problem occured, but the erase operation succeed when I removed the 'for' loop statement and operated them respectively. But now I hasn't got its cause, who can tell me?

Thanks a lot.
