| ===== Installing Images ===== | ===== Installing Images ===== |
| In order to install new images, you must access the login shell through UART-A. | |
| * On the Colibri Evaluation board: use a null modem cable. The communication settings are: 115200 8N1. | |
| * On our [[embedded_systems:imx6:cb|Controller Board (cb20)]]: you need a special USB/TTL-Serial-UART converter cable. The connector on the board is a 6-pin SIL connector, e.g. [[http://ch.farnell.com/ftdi/ttl-232r-3v3/kabel-usb-ttl-pegel-seriell-umsetzung/dp/1329311]]. | |
