Brown" Date: Sun, 25 Sep 2022 21:00:00 +1000 Subject: [PATCH] DFU file work Just grabbing first one for now Expose crc Update CMakeLists.txt Test DFU file Split crc function Fixup Zero init struct Dont null the pointer :facepalm: correct fread Adding tests Create dfu_file.h Format Scratching out more parsing Basic port parser Scratching fread wrapper --- CMakeLists.txt | 8 +-
