download dump file too big 64kb #8

Closed iceman1001 closed 6 years ago

iceman1001 commented 6 years ago

I tested to upload a tagdump which worked nice, then I tried to download it and compare it with my original dump file. All well, but the dump file is 64kb large. Not at all the 1kb which I was expecting.

Something in the xmodem received function is bad

iceman1001 commented 6 years ago

Aha, well.. maybe its in the firmware..

The download of dumps is done via xmodem and this function inside memory.c MemoryDownloadBlock( buffer, blockaddress, bytecount)

It uses the define MEMORY_SIZE_PER_SETTING as bound to how much to send...

Another solution would be to limit the number of bytes that the GUI receives/sends by first querying the current MEMSIZE of the selected slot.

iceman1001 commented 6 years ago

yup. go for that solution :)

bogiton commented 6 years ago

Done. Not very optimal, but it works.

iceman1001 commented 6 years ago

what to do? At least we have something that works on offical revg, offical rebooted and iceman rebooted. Who can complain about that? First get it to work, then make it nicer.
