Tool/software:

Hello, I have ported the code
The falsh related functions of flashAP1_EXIIprogramming
C:\Users\xiaohua\Desktop\013\x15\universal_motorcontrol_lab_f280013x， After discovering normal writing, it cannot be erased and then an error occurs
I selected Bzero_Sector64_start and tried the Instance-EraseSactor() function, but it still couldn't erase properly. Why is this? Is the protection configuration incorrect

    Hi,

    From the screenshot, it is failing at FMSTAT due to CMDWEPROTB value is not set properly set for the sector to be erased.

    In CMDWEPROTB, each bit protects group of 8 sectors from erasing or programming.

    bit 0 -> 32 - 39 sector

    bit 1 -> 40 - 47 sector

    bit 2 -> 48 - 55 sectors

    bit 3 -> 56 - 63 sectors....etc

    If you are trying to erase sector 64 then you have to clear the bit 4 of CMDWEPROTB register.

    Regards,
