I believe you have to buy the DK in order to have full access to the Lemonix OS and LemonIDE?

Connect Serial console @ 115200, 8,N,1 to pins 23,24 (RXD,TXD) of J3, put a bridge between pin 19 and J1 and VCC (or the module won't boot from flash), see Eddy_DK_Programmer_Guide_Eng_V184.108.40.206_9303.pdf, pages 11pp.
Matt Denton wrote:Interesting, so this is pre-loaded on the Eddy board, do you know what the errors are at the end of the boot log?
Also, how long does this boot procedure take?
I have one of THESE, I'm just waiting to get it back from a friend, pretty similar hardware so I might see if I can do something with it
