If you're thinking of updating the firmware (fixup*.dat, start*.elf) on a raspberry pi 4, for example to experiment with the (beta) network booting support, watch out! A series of commits by the Pi Foundation on https://github.com/raspberrypi/firmware in September and October managed to mess up 9pi in various ways. The latest firmware (as of 11 December) is better, except that the gic (interrupt controller) is no longer enabled by default for non-devicetree operating systems. (This has to be done in secure mode before the OS starts.)
To counteract this, add the parameter 'enable_gic=1' to the pi4 section in config.txt. I think this won't affect 9front, which uses devicetree, as long as you update the .dtb files when updating firmware. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T05a9248c31a55ae7-M945afd6d3acc51f533c0c014 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
