I'm trying to upload my firmware but I keep getting first mismatch at byte 0x5300 for most firmwares.
I am using a techzone monotronic board and can't gen much to upload correctly. before I updated the firmware I did a read of the current firmware, trying to upload that shows this error. I downloaded the firmware from the wiki, the precompiled version uploads OK but if I compile it (compiling has no errors) when I upload I get this error. the wiki firmware has the steps/mm all wrong and I can't fix it as anything I compile cannot be uploaded, I can't even upload my backed up original. I were also considering trying the sprinter firmware as noted on the wiki, but it is the same issue.
I am trying to upload with this command line: "avrdude -c stk500v1 -b 38400 -i 10 -p m644 -P COM3 -F -U flash:w:.\build9153871039735707987.tmp\Sprinter.cpp.hex" (with the hex file and path set to what ever firmware I am using)
Yes, I should change to some different electronics but I would rather get these ones working before I try for some upgrades.
