Yes I agree. Designing a new CPU board is a significantly smaller undertaking compared to the previous tasks of CPU board, mainboard, and display board. So I disagree with the 3 year timeline of designing this board. Hardware and basic software support should be doable in under a year. However...

Don’t forget about deep fried twinkies

From what I’ve read, the iMX8M SBC operates around 2.5W (compared to RPi 3 SOC with similar cores running at 6W). Not sure yet what kind of throttling is involved. It’s still made with a 28nm process, but finding an accessible SOC with recent/competitive cores at an improved process will be...

Hell ya we do

The iMX8QM/P (A72+A53+GC7000) should be released pretty soon. Checking digikey, it looks like the price point for this SOC will be around $120, over double the cost of an iMX8MQ (A53+GC7000Lite). There is a raspberry Pi-esque board using an 8MQ which I may pick up to see how the performance...

No I’ve just been playing around with it a bit here and there. I’m constantly rebuilding and flashing and changing things in the OS so I don’t really bother doing much configuration since I’m just gonna wipe it away soon anyway.

No clue :) maybe it already works with the shoulder button.

i3 default modifier is the super key which is way up in the middle of the display. This is the main issue. The rest of the default config is pretty alright. I’d like to make the modifier one of the shoulder buttons but haven’t bothered to look into what they’re mapped to yet :)

Yep the charger driver is already working on the bootloader and the rework of the driver in the kernel is well underway. It will be done very soon (probably by the end of the weekend but no promises). Following that will be the rework of the battery fuel gauge driver. This is a separate chip...

Yeah it can definitely run Android. OMAP5 Android support is not very recent though (I think 6 is the most recent). The low level support for newer versions just isn’t there and is at least a year of work to fully implement. Personally I’m pushing for an updated CPU board based on the iMX8QM...

I don’t think you quite understand how this works. YOU are the investor. This is not a PlayStation or MacBook. This is just a guy with an idea who found a community interested enough to contribute to help make it happen, whether it’s upfront payments or volunteer engineering or both. If you...

I have a unit with the grey case that ED sent me a while ago for development. I gotta say the video makes it look worse than it looks in person. Sure the discolorations are there and a little more prevalent than you’d find on say a Nintendo DS, but they don’t seem out of the ordinary. Nothing...

You’re either having a bad day, or don’t understand the amount of energy and effort goes into a project like this. It’s amazing what ED has been managing to pull off almost on his own with volunteers as engineers. This is a big project. If you think it is taking too long and want it to speed up...

Thanks aTc. I’ll look into this further this weekend. Pyra charging is fully handled in hardware. The charger chip will operate autonomously with some default settings until the bootloader runs and configures it for fast charging. The charger stays powered by either USB or battery at all times...

Ok I’ll update my bootloader to use extlinux like the old one does. I want to keep some user configuration of uboot environment in there, so perhaps I’ll have it run a uEnv file if it finds one before running extlinux, since to my knowledge, extlinux doesn’t seem to support modification of any...

Yeah that would be done through sysfs. Alternatively you can modify the driver also.

The kernel is loaded by the final stage bootloader. The kernel exists in RAM. The initramfs is a simple filesystem which the lives in RAM as well which the kernel mounts. It’s primary function is to assist the kernel in mounting the full filesystem. In some cases, it is not necessary. For...

Kbuild is simply the build system for the kernel. There are four (sometimes five) major components to a Linux system. The first is a bootloader (described above). The second is (of course) the kernel, which gets loaded into RAM and handles scheduling, contains drivers, handles all the meat and...

LFS is incredibly informative, but it’s quite a bit off the bat. It’s very good, but definitely doesn’t teach you about Linux in an embedded environment such as the Pyra. Most importantly, you won’t learn about the boot process of an embedded Linux system. While every SOC behaves a little...

The OMAP5 is a pretty old SoC. I haven't tried it, but I have a hard time believing it will handle VR well at all. Someone with prototype hardware may have some VR hardware and can check it out though.
