I wish microcontrollers came with the option (configured via pins or something) to always boot into a bootloader mode, where they expect to receive firmware via some serial connection. It's so common to have a Linux SoC and some MCUs in one product. Everything would be SO much simpler if the SoC could always just upload FW to the MCUs on boot

Currently, you have to flash MCUs during manufacture, and you need to implement some FW update process from the SoC. It sucks

#Introduction
I've been on Mastodon for quite some time now, but under another name. I started a new account because I decided to take a step back from world news, collapse, climate change, hunger, war, fascism and inequality.
In short less doom and gloom and a little bit of positive small scale projects that might also inspire or help others.

With this account I'll focus more on my day to day life, the things I do and make.

Of course I sometime still will post concerning subjects that provoke my rage or frustration. Sorry, it's not all moonshine and roses.

Having said that, I've a broad range of subjects that have my interest, so hopefully something useful will stick with you.

From my profile text:

#Collapse aware person, born @ 320 ppm CO2, world population 3.1 billion.

Fighting depression and #sadness by doing some positive and small scale things that might help people.

Too many interests, like:

🚀 Retro just got Modern!
In today’s video on DevWithZachary, I explore the Clockwork PicoCalc — a tiny yet mighty handheld computer powered by the Raspberry Pi Pico.

With just 264KB of memory, this device can run C, C++, Python, and Lua — proving that powerful programming doesn't always need modern specs.

What can you really achieve with less than 300KB? Let’s find out. 👇

Do you know an low power #SBC which has got both an #AP(Application Processor) and an #MCU(micro controller) and TRMs(Technical reference manual) are available in English in the public?

I don't need something fancy. A Cortex-A7 for the AP with at least 128MB RAM is enough. #riscv is okay too.

The only one I know is #milkvduo. The SoC has got an application processor(either RISC-V or 1xCortex-A53), and two MCUs.

Also I want the SBC to have #Wifi.

Also I want something cheap. not more than 25 USD.

I want use it to build a #customkeyboard which could also act as a micro PC:
