[Uisp-dev] Intel-HEX 01,03,05 record type - no checksum

[Pavel Celeda]

Hello,

I'm starting with AVR and Ethernut. I tested Ethernet Boot Loader
http://www.ethernut.de/arc/eboot100.zip and get Intel-HEX checksum
error. Originaly file eboot.rom contains record :040000031000E00009.
UISP discard record type 01,03,05, don't calculates correctly checksum
and fails to upload the hex file. Following patch solves this problem
:).
