Yep. I realize now I made a big mistake not communicating with HNS first. My main intention was to have this be the main PyraOS kernel. It is based on Letux, but is managed separately from it so it can stay up to date with the most recent Pyra features and fixes. In the meantime, once they’re...

I am but a baby. I also lived in Santa Cruz, CA for the last 7 years, it just goes with the culture ;)

This does not work well when we do not have good control over the repository. We cannot easily create branches and set rules to ensure safe collaboration amongst the community. HNS would have to do all this, which adds difficulty on his end when all he is really interested in is the working...

Thanks for the summary ED. I agree with all of those points. I do not want to fully separate from LetuxOS. That doesn’t benefit either party. PyraOS misses out on modifications by you, and you miss out on modifications by the community. However, due to the points ED made, it does make sense to...

Thanks ED!

Hey guys! I just got involved helping develop PyraOS. My main goal is to unify and stabilize development of the OS and create a build system which can reliably generate images cross platform. To start, I have created an official fork of the kernel which I will be maintaining. It lives inside...

I have access to OMAP5432 devkits so I could potentially boot on there. Depends how far they stray with Pyra hardware. But it definitely wouldn’t help too much as the things which need work (other than 3D) would be unavailable on the dev kit. However, the xorg issues could potentially be flushed...

Heyo. I’ve been seeing some stuff lately about some crucial things that still need to be done on the low level Pyra software and not enough devs to do it. The things which seem most crucial appear to be in the bootloader and kernel drivers. I’ve got some experience doing board bringup for...

Where do you see that? I don’t see anything indicating that to be the case.

I think a lot of companies with more limited resources have struggled with the jump from Android 7 to 8+. There are very significant changes in the hardware layer architecture.

SiFive has a board that I believe currently has people working on Linux support for. https://www.sifive.com/boards/hifive-unleashed

It worked on the OMAP5432? I see that there’s support on the OMAP4 but that’s a different GPU and those SGX are closed source and notoriously difficult to integrate.

No one's been able to get the SGX up yet on the Letux kernel right?

I was originally talking about the iMX8M in my first post. I should have been talking about the iMX8, which is currently in preproduction which is why you may not know that it existed. I haven’t been able to find much info yet on the TDP but I did get to play with it a bit at an NXP conference a...

The iMX8 actually uses A72s and A53s. Looks like it’s ARMs new big.LITTLE architecture which utilizes high performance cores in times of need and high efficiency cores in other scenarios. That Amlogic seems interesting. Any idea what availability is like and how the BSP support is? I’m a...

Now that we can see the Pyra on the horizon (hello little guy) has anyone put any real thought into the next version of the CPU board? Unfortunately now that we’re nearing the end of the initial development of the Pyra, the OMAP5 is pretty dated. Personally I think an iMX8M based CPU board...

This is informative. But do you think that hundan's issue is related to compilation/linking problems? From the description, hundan has placed identical binaries into two (I'm assuming) identical pieces of hardware. One works, one doesn't. Sounds like a hardware issue to me.

This is not particularly relevant, but the -mmcu option is a compiler option which specifies the instruction set being used. http://gcc.gnu.org/onlinedocs/gcc/AVR-Options.html

hmn's theory does sound plausible, but I can see in your compile options you are including the -mmcu option. What you say here sounds like there may be an issue with the hardware. Can you tell us more about the hardware setup? Is it a custom board?

Are the M4 cores on the OMAP5 missing the FPU? I guess this wouldn't be too much of a surprise since their main purpose is to be used to control the image processing unit. From the TRM it appears they have a direct connection to the DSP core which could be interesting. I still have more...
