A login shell can be accessed through UART-A on the Colibri Evaluation board with a null modem cable. The communication settings are: 115200 8N1.
If you are using our 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
If you use our standard rootfs as described above, you have GCC 5.3 installed. For crossdevelopment you need the same toolchain (same gcc and library version) on the host and the target. Download this toolchain from out FTP: inf004/ftp/colibri_imx6/RT/host_tc_arm_gcc5_3_RT.zip
and extract with
$ tar –xzvf host_tc_arm_gcc5_3_RT.zip
To build an application for that system, provide CMake the path to the CMake toolchainfile. This file can be found in your toolchain folder and from there navigate to /usr/share/buildroot/toolchainfile.cmake
.
UART-A (used for console, see above) and UART-B can be accessed on the cb20 board. Both can be written to with
echo "hello world" | sudo tee /dev/ttymxc0 # for console echo "hello world" | sudo tee /dev/ttymxc1 # for UART-B
After loading your new rootfs run the initial-setup.sh
script in /opt/cb20/bin
to allow the generation of SSH-Keys. Also the read-write partition mounted at /mnt/data is formatted.
