We have a Serial-to-USB cable connected to the Serial interface of the board and a USB port of the testing machine. Then you can catch the output via 'picocom' for instance. The implementation of the UART driver is [1]. It uses 1 stop bit, a baudrate of 115200, and no parity. So, the following works for me:
sudo picocom -p n -b 115200 /dev/ttyUSB0 Even if your Genode doesn't come up you should at least see some output from the Uboot like this: U-Boot 2015.10-00237-g92e40f5-dirty (Dec 04 2015 - 15:37:04 +0100) CPU: Freescale i.MX6Q rev1.2 at 792 MHz Reset cause: POR Board: Wandboard rev B1 I2C: ready DRAM: 2 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 No panel detected: default to HDMI Display: HDMI (1024x768) In: serial Out: serial Err: serial Net: FEC [PRIME] Hit any key to stop autoboot: 1 U-Boot SPL 2015.10-00237-g92e40f5-dirty (Dec 04 2015 - 15:37:04) Did this help?
