EEPROM Загрузчик для MIK32 (K1948BK018)
В данном тексте я написал про то, как я написал загрузчик для российского микроконтроллера MIK32 ( K1948BK018 ). Это, пожалуй, первый случай, когда столько функционала мне пришлось утрамбовать всего в 8kByte ROM памяти.

As a proof-of-concept, changing 3 lines made our pmOS image "just work" using tow-boot!

We're ready for #SPIflash on the #PinePhonePro @Pine64, just waiting for you ;)
Modules like #SPIflash are really important to achieve the goal we've set at #postmarketOS: device support for 10 years and more. Once a device is fully mainlined and can boot using a generic #UEFI image we no longer have to put any effort in supporting this particular device. Everything will "just work". Just like no distro put any effort in making it boot with my particular desktop and laptop.
Flashing so-called "platform firmware" which implements #UEFI, like u-boot, to this #SPIflash would allow the user to boot generic UEFI images not made specifically for the device in question. Finally you'd be able to properly live-boot a distribution through e.g. sdcards, USB sticks, etc. And you no longer have to wonder if your distro supports your particular device, you just have to download their generic UEFI image!

Did you notice that rather than on PC where you download a generic image which you can just live boot from USB, on ARM every distro needs to support every device individually? It's not just lacking mainline Linux support, it's also lacking a generic way to boot these devices like x86 has. #SPIflash can solve this perfectly by implementing UEFI on a dedicated chip but current new @PINE64 devices are lacking this. Let's get loud to make them add this again in new devices!
