I’ve managed to get a serial console working with sosboot from the ac100 folks. The display doesn’t work, but you can get a console on the serial port.<\/p>\n

\"photo(7)\"<\/a><\/p>\n

In the above image, I’m calling pin 1 the top most pin, when the PCB is installed this is nearest the front of the case.<\/p>\n

From the PC perspective (i.e. rx, means PC receving data) the pin signals are as follows:<\/p>\n

pin 2: rx
\npin 3: tx
\npin 4: ground<\/p>\n

You can communicate at 115200, 8N1.<\/p>\n

You should be able to see a boot message from the Nvidia boot loader (see my previous post). The ac100 kernel from sosboot-r3 also brings up a serial console. I’ve modified sosboot to start the serial on the serial console rather than the display download here: http:\/\/41j.com\/hackedsosbootr3.img<\/a>.<\/p>\n

That will give you a kernel with serial console but no display\/keyboard. The Nvidia kernel (mentioned in previous post) appears to give some display functionality, but no keyboard and no serial port.<\/p>\n

Update: Here’s an image with a working display and serial (the original android kernel) it runs a console on the serial port: here<\/a><\/p>\n
