Hey everyone, I've managed to get RTEMS6 on the Raspberry pi 4B rev 1.4. Every test ran fine except for minimum.exe, It gave a fatal error.
Here's my setup for running RTEMS6 on RPi4B: TF-A is required to enable GIC on RPi. I had tried to use armstub-gic.S ( https://github.com/raspberrypi/tools/blob/master/armstubs/armstub8.S) but it didn't work out. TF-A on other hand did work pretty well. Steps to get TF-A binary are described here: https://trustedfirmware-a.readthedocs.io/en/latest/plat/rpi4.html Config.txt section: arm_64bit=1 enable_uart=1 gpio=22-27=np enable_jtag_gpio=1 dtoverlay=disable-bt kernel=kernel8.img enable_gic=1 armstub=bl31.bin RTEMS6 My branch (noov-dev): https://github.com/0xnoor/rtems/tree/noor-dev
