Hello,
Does the current RTEMS version support the Jetson nano board, if
not, do you think It will be a good project for gsoc2023? something
like porting RTEMS to Jetson nano or jetson AGX orin maybe?
I'm torn whether this is a good project or not. It is quite ambitious
but it appears that a fair amount of the boards horsepower is tied to
binary blobs which likely won't work with RTEMS.
One challenge is that much of the support will be GPL licensed which is
unacceptable for RTEMS.
That said, it may be feasible since freebsd appears to support it now. I
have no idea what devices work under freebsd. But if you can boot
freebsd on it and see what works, that would be great information.

The other side of this is how useful this will be either for RTEMS
users. What would a hobbyist use it for? A production team?
Is the board too old to be worth the effort for the limited audience?
The Jetson seems to be a big familiy. The Nano is from 2019 and has some
chip that is most likely based on a chip from 2015? The Orin Nano is
from September 2022 with some CPU that I didn't find on a quick search.
Otherwise, I fully agree with what Joel said: Do we have some audience
for it? They are not really cheap so hobby use is unlikely.
I haven't found any source where I could buy small numbers of blank
chips. In my experience, that often means that the manufacturer targets
products where they sell big numbers of chips (at least 6 digit
numbers). For these it's usually cheaper if the manufacturer just
assigns a field application engineer to you instead of writing good
documentation. If the Jetson falls into that category, it's not an easy
project.
Honestly I'd rather see a new BSP for a decent RISC-V board.
Decent and not too expensive RISC-V would be interesting, but I haven't
found too much of these yet. Only expensive stuff like the Renesas
RZ/Five evaluation board or ones that are not yet easily available like
the Pine Ox64 that I mentioned in other GSoC discussions already. If you
find a nice cheap RISC-V board, it would be a great project. Other
commonly available and well documented non-RISC-V boards or simulator
targets can be interesting projects too.
Best regards
Christian
Looking forward to your response.
I'm also curious to hear what others think.
