So after a reboot the BananaPi was no longer accessible. Connected it via HDMI and saw the following :
The root fs was moved to an usb stick a long time ago - it became /dev/sda1 - and this worked great until now.
uEnv.txt on the SD card contains :
bootargs=console=ttyS0,115200 console=tty0 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 disp.screen0_output_mode=EDID:1280x720p50 hdmi.audio=EDID:0 console=tty1 root=/dev/sda1 rootfstype=ext4 elevator=deadline rootwait
aload_script=fatload mmc 0 0x43000000 script.bin;
aload_kernel=fatload mmc 0 0x48000000 uImage; bootm 0x48000000;
uenvcmd=run aload_script aload_kernel
I've mounted the SD card on another computer, removed the bootm 0x... part from aload_kernel, but still it tries to boot from network.
Any ideas on how to fix this?
