mikejohnson Posted July 2, 2017 Report Share Posted July 2, 2017 Hi I bought one of these DUO 2MB boards a while ago but I've just got to start playing with it. I'm failing pretty early on, and searching older posts suggests I'm not the first. The message I'm getting is: Programming to SPI Flash Using devlist.txt Invalid chain position 0, position must be less than 0 (but not less than 0). Unknown Papilio Board Using devlist.txt USB transactions: Write 2 read 1 retries 0 Invalid chain position 0, position must be less than 0 (but not less than 0). IOException: Cannot open file I have swapped cables, and tried an account with no spaces in the name. No luck. Anyone got any ideas or am I looking at a faulty board?
