You need to manually revert the change byīuilding u-boot using configuration rpi_3_3b_defconfig is going to NOTE: Automatic revert is not going to work if you are using the This will enable you to get the most up-to-date U-boot which will boot Make CROSS_COMPILE =arm-linux-gnueabi- rpi_3_32b_defconfig If you choose to build your own U-boot, then clone U-boot from upstream, Use this prebuilt U-Boot binary image which already works. In order to obtain a U-boot binary that disables caching, you can eitherĬompile U-Boot from source yourself, or you can Unfortunately, the stock upstream U-boot used toĭisable caches before loading the kernel image, but as of this patch This problem can be remedied by having U-boot disable cachesīefore loading seL4. On the RPi3, because of cache configuration issues in the seL4ĮLFLoader. Right now, the default U-Boot will not successfully boot an seL4 image Short the jumper marked “RUN” between the expansion header and USB sockets to Serial TX and RX are located at GPIO pins 14 andġ5 respectively (See Hardware schematic above) Reset On our blog (and check out the rest of the blog too!) Serial connection Please also find a feature article going on seL4 the Raspberry Pi 3 RPI-3B-V1_2-SCHEMATIC-REDUCED.pdf Feature This is an experimental port and is not guaranteed to work.
