Hello,

I found a mistake in IAP from ST in source:ymodem.c

If the file is between 64K and 128K, the protection of sector1 is not diasbled -> you cannot write data in this sector.

change the source in ymodem.c in Ymodem_Receive () as follws:

else if (size <= 0x1FFFF)

{ /* Disable S0 and S1 write protection and erase them */

FMI_WriteProtectionCmd(FMI_B0S0, DISABLE);

FMI_WriteProtectionCmd(FMI_B0S1, DISABLE);//This missing

FMI_EraseSector(FMI_B0S0);

FMI_WaitForLastOperation(FMI_BANK_0);

FMI_EraseSector(FMI_B0S1);

}

Best regards

Hello TRuf,

Yes, you are right. This is known and will be corrected in the next IAP release.

Thank you.

Best regards,
