Hi there! Sorry for my late reaction to your answers, school kept me quite busy the last weeks. Instead of replying to each mail, I have created a summary, I hope this is acceptable.
The suggestion to insert printf's in the kernel to check how far the boot gets is not really an option for me, I feel that I do not have the experience with OpenBSD to know were to start. When I try to boot the kernel into ddb the serial connection freezes and I am unable to enter any commands. I tried NetBSD 7.0. It boots fine and on the first boot it resizes the partitions to utilize the whole SD card. Problem: the network interface is not working. It registers in dmesg as awge0, but it does not show up in ifconfig -a, and I cannot use it with the DHCP client or even set a static IP address. I have experimented a bit more. It seems like bitrig version 1.0 [1] is able to boot on the board. The boot gets interrupted and asks for a boot device. Entering tmpfsrd0 manually works. It then start the installer. It detects the network interface as sxie0. Using dhclient (or through the installer) gives me: > DHCPDISCOVER on sxie0 - interval 1 > send_packet: No buffer space available I am able to set an IP address manually, but then I can only ping myself. Other hosts on the same network are unreachable (and the LED does not show any activity on the interface either). If I continue the setup without configuring the network, I can continue until I have to select the device to install to. The SD card does not show up in the list. Below there is a full boot log and a dmesg from the bitrig system if anyone is interested. I guess I will keep poking around. Thankful for any input.
