Blue Pill, HID Bootloader 2.2.2, segmentation fault
Posted: Mon Oct 23, 2023 5:52 am
Hi,
I tried to upload Blinky via HID Bootloader, according to this video: Blue Pill Bootloader. The only difference: I used ST-Link v2 for uploading the bootloader.
My steps:
1. Unzip stm32_binaries.zip from release 2.2.2
2. Upload file stm32_binaries/F103/low_and_medium_density/hid_generic_pc13.bin via STM32CubeProgrammer, option ST-LINK, address 0x8000000, success.
3. Set project tools, Arduino IDE 2.2.1:
Board: "Generic STM32F1 series"
Port: "/dev/tty/ACM0" (grayed out)
Debug symbols and core logs: "None"
Optimize: "Smallest (-Os default)"
Board part number: "BluePill F103C8"
C Runtime Library: "Newlib Nano (default)"
Upload method: "HID Bootloader 2.2"
USB support (if available): "CDC (generic 'Serial' supersede U(S)ART)"
U(S)ART support: "Enabled (generic 'Serial')"
USB speed (if available): "Low/Full Speed"
4. Disconnect ST-Link, connect USB, (the Blue Pill LED starts blinking real fast), push Arduino IDE's Upload button to upload Blinky with some Serial output. My console output:
Sketch uses 27644 bytes (42%) of program storage space. Maximum is 65536 bytes.
Global variables use 4532 bytes (22%) of dynamic memory, leaving 15948 bytes for local variables. Maximum is 20480 bytes.

Failed uploading: uploading error: signal: segmentation fault (core dumped)
As I understand, "error, counldn't open [/dev/ttyACM0]" is no error at all, because the port is to be emulated after the successful upload. But the segmentation fault is...
What could be wrong?
NB The bootloader output says "v2.2.1" but it's been downloaded from 2.2.2 section, checked.
