first time loaded fine, I do nothing, just load again.

Do you have to reboot to get it to work again ? From the loader output, it seems that the design you loaded in the FPGA does not initialize the i2c pins as 'Z' causing the i2c bus to be messed up. Le 14 août 2015 12:13, "Jonathan Chetwynd" notifications@github.com a écrit :

I have not yet got a good handle on the inconsistencies, cf camera. from my position of ignorance, it would seem to be helpful if code was commented. loader is a critical piece of work. when testing one can waste a lot of time. I'll try to add some further examples as I find them.
