This gui and notes look excellent, seem to have a few issues though.
What .net version are you using to compile? The make file is calling for a directory that doesn't exist.
Any chance you could put these .cs files in a visual studio project and make a proper project / .sln file to compile and make any gui mods.
The Arduino detection code seems to be broken for Arduino clones.
I imported a LPDDR4X .SPD .bin file and it didn't detect it or make a checksum attempt.
Thanks
