stm32-bootloader VS IronOS

Here's a bootloader "library" that might be useful. You need to add your own code to get the actual firmware image from somewhere (UART, an SD card, or whatever), and then you just pass it off to the "library" for flashing.

Yes, unless you have something like an STM32 with a built-in bootloader. This can be used to update the regular bootloader. For example, this bootloader is capable of jumping to the built-in bootloader from software (as opposed to the "regular" method of pulling certain pins high or low at reset to cause the processor to run the built-in bootloader from ROM rather than the regular bootloader from flash).

So apparently the Pinecil is a BLE-enabled soldering iron with a 108 MHz RISC-V processor running a custom real-time operating system [0]. The author wanted to access the UART logs, so they repurposed a Raspberry Pi Pico (a dual-core microcontroller system running a real-time OS) for the task.

That's a staggering amount of hardware, sortware and computing power devoted to decoding one of the simplest and oldest serial protocols from a device whose sole purpose is to essentially melt tin. Maybe I'm out of touch, but I think I'll stick to my thermostat-controlled Weller soldering station and FTDI UART converters. I apologize if this post comes across as snarky, my point is that these are solved problems and have been for half a century.

I got a TS101 and wanted to switch to IronOS straight away as it seems like an improvement to stock firmware. On the website it says that TS101s are supported, but there is no file for it. I figured it must be the TS100 .hex file, but flashing it just gives me an error (a .NOT file). Is the TS101 really supported and how do I flash the firmware in that case?

but the pinecil can also use IronOS https://github.com/Ralim/IronOS

Look at this ticket in Ralim's IronOS, all 4 people same issue and all they had to do was clean their Cartridges with IPA 90-99% Alcohol. https://github.com/Ralim/IronOS/issues/1601

I'm very happy with the Pinecil. The $25 price is very reasonable for a reliable soldering iron that is open source hardware[1] and runs on free and open source firmware.[2]

Also, I'm not sure what exactly is happening with the OS on the irons, because I thought the pinecils shipped with IronOS but it may be an old or cut down version because when I loaded the latest https://github.com/Ralim/IronOS on my pinecils I just ordered two weeks ago, I definitely got a ton of options I didn't have before.
