Documentation for r0.2.1 #39

Open nicolasnoble opened 2 years ago

I got a pair of boards from https://1bitsquared.com/products/orangecrab and what I received are in fact r0.2.1 boards, which I can't find documentation for. When connecting the boards through USB, they start the default blinking bitstream, but no usb device appears in my kernel logs, even though I'm using a data USB-C cable. I'm not too sure how to proceed without documentation about them to troubleshoot what's going on.

Hey @nicolasnoble, The docs are identical to the r0.2 board, except for a connector change for the USB/JTAG, and some changes to the DC/DC circuits.

If you hold down the button while connecting the USB then the DFU bootloader will appear.

@gregdavill I think you should acknowledge the r0.2.1 in the README.md file and the OrangeCrab Web site to avoid confusions. I have to figure out the same issue.
