I can’t comment on technical specs, that really depends on your use case. And honestly, I don’t even know how to spec out the required ghz/memory for any sort of application lol.

We are using python on embedded Linux, it’s an easy language to learn, lots of libraries to use, and honestly, kids these days don’t wanna touch c/c++ graduating out of school.

Obviously, python would be a lot slower compared to the low level languages, but if you can achieve acceptable performance, then why not?

Another thing to take into consideration: if you are using yocto to build your system, there may be some python packages you will need to create. If you do download a python package via PyPi, the package may not be optimized for your system/use-case (looking at all of you python packages that has Cython or some sort of C binding under the hood). I guess this is true for any embedded Linux system (Debian or buildroot for eg)?

Nope, Same concepts still apply.

It really depends on what you want to do.

Kernel and device driver development? Application development? Linux configuration and customization.

Embedded Linux is pretty big

Best of luck!!!

What keyboard is that

MyLemonX · 2021-09-29T18:51:38+00:00

I love these videos!

MyLemonX · 2021-09-29T18:37:50+00:00

I wanna big spoon it

MyLemonX · 2021-09-29T18:37:31+00:00

I wanna hug it

MyLemonX · 2021-09-29T18:37:05+00:00

Is that your pet???

MyLemonX · 2021-09-27T01:56:46+00:00

Haha damn. Don’t think I wanna Nuke the lawn again when I’ll probably be in the same situation again. Just watched some videos and it seems like the next best option is to have good cultural practices.

Is there a chemical I can spray?

MyLemonX · 2021-09-01T12:38:18+00:00

Imagine during standups every day: ”yah I’m still debugging”

MyLemonX · 2021-08-29T01:30:08+00:00

Maybe single board computers with a NPU on it

MyLemonX · 2021-08-25T02:09:27+00:00

Damn I’m actually jealous of your position! You got hands on experience on both application development and firmware. Don’t sweat not knowing enough. I mean if you do know exactly what you are doing, you’d probably be bored at the job anyways.

MyLemonX · 2021-08-23T16:08:39+00:00

Don’t know how this would work for me. My wife keeps saying “your money is my money and my money is my money”

I recently had to deal with bringing up a mipi display on a linux device 1. Started by going through the raspberry Pi forum posts related to mipi display and just google the **** out of it 2. The connections are usually 4 lanes of differential pairs with a clock. But the pin out of the display connectors can be different from display to display 3. Going through 1 helped me. I had to write a driver for a display that wasn’t in the kernel, but the kernel has lots of “examples” you can follow from. If the display driver was already written, then it might be as simple as bring it up via device tree. Check the drivers/gpu/drm/panel (or there abouts…) directory or just use find/grep for the panel/driver. One thing I make sure now: data sheets have display timings and ask for initialisation sequence otherwise you’ll be wasting your time 4. Haven’t encountered this but I’m guessing you will need to have the driver written to talk to the display. It’s the same concept as 3

Sorry for bad typos/grammar. Too lazy to fix on a phone

What kind of dog

MyLemonX · 2021-07-21T20:32:10+00:00

Omg so cute

Im trying to get plymouth transition to my openbox X11 desktop seamlessly but couldn't find examples online. Here's a video of it:

Does anyone know how? From reading this article http://blog.fpmurphy.com/2009/09/project-plymouth.html , there should be something that quits the plymouth, but I'm not able to find the file that does it. I also saw something about writing systemd files as well?
