How Linux Boots on an Embedded Device - part 1 

You will get lower initial bump in viewership metrics on this video, but please don't let that discourage you. Not only people will search for and watch this for a longer time, many would come back to watch again for specific references. RU-vid analytics makes creating the popcorn content more rewarding than hearty meals like this, but please don't let that get to you. Thankfully you actually have a product to make (instead of breaking it as a RU-vidr as your primary goal) so it gives me hope that you will not break to the pressure of algorithm & I can keep coming back for more great content that RU-vid is desperately starting to lack.

It's awesome you started this series. From what the previous videos looked like, the router will probably be a really nice device. In addition to that it could be a great learning opportunity when we have those videos (+ maybe good documentation).

just PSA... embedded engineer here. You actually do NOT need a JTAG programmer to walk in the 2nd stage boot loader on many SoCs including NXP. Now, I'm not familiar with your exact SoC but I am with other iMX and S32 SoCs from NXP as well as Jacinto processors from Ti and they all have CPU pins you pull up or down to tell that first stage boot loader, in the CPU, where to look for the 2nd stage boot loader - such as a serial port you connect over USB.

I don’t want to say ur doing god’s work here. But definitely work of many professors of CS around the globe! Beautiful work!

I like the way how you share interesting things on the way up .. As usual, Good luck ❤

I would seriously consider to buy the device I understand its inner workings. Great series. Thank you.

a full tutorial will be great

You’re doing something you’re passionate about and sharing it with an enthusiasm that is absolutely enchanting. Randomly coming across your video series has encouraged me to upgrade my network and learn more about how networking works. Kudos~

I watched all the videos , even though I'm not a programmer at all . I'm just curious how your enterprise is evolving little by little. I'm here since you "hacked your isp" video . very interesting channel you have here . keep going .

I... understood a few of those words! :D This is way above my knowledge level, but it's still very enjoyable seeing how you progress.

Haha, chatgpt is probably the most computationally expensive way to convert hex to decimal 😭

This series is incredible, man I will buy one for sure. That is exactly what I wanted, ubiquity won't have my money. Overkill, I don't care lol

Awesome content once again! I hope your project continues going from strength to strength. Did you make contact with the team over at Vyos?

20:48 - Ahh. The pesky CRC checksum mismatches... I recently added CRC error detection to the filesystem I've been working on, I can say confidently - It was a pain.

Excellent tutorial series, Tomaž! 😎👍

I love this.

Say you will be able to boot vyos and your device will sell good, and by how things seem to be going , this is very likely, how would you license vyos ? I'm absolutely sure that it would benefit them, maybe even more than you, as it would be a better appliance for the os, but would you be allowed to preload it ? Congrats on your work!

Nice!

Why not using a risc-v chip? Arm will be expensive in licensing. If you want uptimized router then you could also use a fpga

Isn't ls1046a supported by openocd (even with a config for ardb)? Hence the claim that working with JTAG requires software with a large license cost is false?

And a reminder to all, this is still peanuts compared to the shit you’ll have to deal with should you choose to do all of this manually.

At 10 minutes when talking about erasing the nor flash, you say 7 zeroes, but only typed 6

Also no, save yourself the hassle, anything but GPT! That thing has zero clue on this with all the confidence!

Always bragging you have an ARM SoC that has vendor support and documentation

And this is exactly why i hate Linux.... its way overcomplicated for what it needs to be. 😂
