Hi,
I am using an ST7FLITE05 and would like to know if it is possible to verify code in the controller if the read protect bit is set.

Thank you for help.

Hi,

Of course you cannot verify the code in a chip that is programmed: "Verify" means "read and compare against expected", and since we cannot read a protected part...

However, if you use RFlasher or ST7_pgm, you will be able to execute the "program and verify" operation. In this configuration, we program the flash, then the option bytes except the protection bit, then all this is verified, and in the end we program the security bit. That's the best we can do.

Best Regards,

Vincent
