Hi Developers,
reading words from flash using the butterfly protokol in
butterfly.c: 'butterfly_read_byte_flash'  you are using "g\000\002F" which means read two bytes from Flash as the flash is is little endian byte order it delivers LSB first not MSB as you assume later in that funktion (u are turning the bytes).

-reading the flash with the -U f:r: commandline gave correct contend
-reading using the read funktion in terminal mode turned the bytes
-using the jtagmkii both modes returned the correct content

Yours Karl Fessel
