Thanks for your work, but would you attach it again? Is giving error in rar file.

Use latest winrar version for unpack it

That was exactly it, my winrar was outdated.

Unfortunately I will back working in the car in a month, but as soon as I do I will post the final result.

Thank you again.

I have a doubt, I have been writing an MCU again and with an error, just in the first line of the file, instead of 'FE' is 'FF', is this normal? What should I do?

In the image I put the error that happens in xprog at the time of write, and in the software 'compare files', on the left is the file that you provided me, on the right is the file after write and read again on xprog
