I am looking to purchase a board for a project that will use sel4.
I have the following hardware requirements:
- serial port
- potentially usb
Then, I want to run linux on top of sel4 and have also some native
<https://sel4.systems/lists/listinfo/devel>The BBB does have a way to run
from a uSD card as does the latest Raspberry Pi.
The programming and tools on the Raspberry Pi seem a bit richer.
The BBB environments want to program the flash memory and that can take
a long time. There are some developer tricks to null it out and boot from
The R-Pi will boot a new uSD card image quickly.
The new R-Pi has an abundance of USB ports so you can
boot an OS on the uSD card and load a spare uSD image on
a card mounded on an adapter. This allows quicker development
Start with the bootstrap code and have it load a sel4 image (not vmlinux).
It is necessary to have enough support in sel4 to manage (start/stop) your
Since the new R-Pi is multi core you can address MP or constrain yourself
to one single core. Multiple cores have value if you want and OS to be
Both are interesting and I have both -- the R-Pi seems to be the best
supported at many levels with some foot notes.
this next tells me that interrupts are a hardware problem.
