Flash loader issue

macca

Hi,

I was trying to upload a program to flash using PNut's flash loader code and found an issue, maybe a bug: if the binary data (flash loader + program) is uploaded with checksum check (the stream ends with 4 checksum bytes + question mark), the flash programmer checksum check fails, however if I upload the same data without checksum check (stream ends with tilde) the flash programmer works perfectly. This means that the whole packet is correct but for some reason the upload checksum check causes the loader code to fail.

Is that a bug or do I need to do some additional things to allow the upload with checksum check ?

Best regards,
Marco
