How to use with PlatformIO?

[Kenjutsu]

Good day

How do I use this bootloader with PlatformIO?

It works perfectly under Arduino without fail, so thank you so much for your hard work on this. Under macOS, I have found that only Serial upload worked perfectly each time. Now I can add the STM32 HID bootloader to this list

TIA

With platformio you can define your own custom uploader

Thank you for your reply. I started working on a custom uploader, which was able to find the PB and started uploading, but the blink program never executed and the serial port was missing after the upload. I knew it had to do with some build flags, but I had no idea which ones, so I put it on ice.

By chance, I read this post stm32 shows up on dmesg but not in arduino ide #34 which lead me to Notes on using STM32F103C8T6 Blue Pill. I watched the video How to Install the STM32 USB Bootloader - Tutorial Video. Towards the end was info on how to get the HID bootloader working in PlatformIO. I modified my platformio.ini file accordingly, but the upload failed with sh: hid-flash: command not found

A quick Google led me to [sh: hid-flash: command not found] Error when using hid upload protocol with stm32 bluepill. The fix is to copy the appropriate hid-flash program to the appropriate folder. I do not have framework-arduinoststm32-maple so I downloaded and copied hid-flash from STM32_HID_Bootloader

Now, everything works fine
