Self-Verify failed on non-aligned hex files

[amink-liquip]

I used this code to understand what is going on UBHA's side and it was very helpful but I found out that some hex files with non-aligned hex addresses cannot be programmed on dsPIC33 devices (like :10D6940073xxxxx). The same thing happend on my onboard programmer which employed Zephyr OS to reproduce UBHA actions. I fixed the issue by putting extra heading 0xFF before the sent data and it worked for me.

Hello @amink-liquip and thank you for the bug report!

Please run mcbootflash with the --verbose flag and include the output in a comment to this issue.

If possible, please also include a copy of the problematic HEX file. If you do not wish to upload it to the public bug tracker, you can send it to me privately at alexander.bessman@gmail.com.

@bessman
The Hex file is a simple bulky code and does nothing but sending data on UART, so I put it here for you:
master.X.production.zip

I see you are using mcbootflash 8.0.1. I fixed an alignment bug in 9.0.0, please try the latest version and let me know if it still doesn't work.

Yes, it works with the new version, thanks
