Otso, FYI: I've started writing the ENCx24J600 driver. Looks simple and straightforward, just work. I'll make it separate from the ENC28J60 driver, as it will most probably be smaller (smaller flash footprint) than the ENC28J60 driver, if done right. My current estimate is that I'll have first version ready by Monday or Tuesday. It may or may not be complete, but in any case should be good enough for testing on Wednesday. As usual, I will most probably run out of time before we'll get it fully tested, though.... Asif, What's the situation with SPI library test cases? Do we have any yet? --Pekka
