FNIRSI GC-01 (APM32): Linux flash tool

[VisualGadget]

Hello!

I really want to flash my GC-01 from Ubuntu without using special tools like ST-LINK or switching to Windows. Here is the script I made and want to share. It simplifies flashing process to one script run.

Here is the workflow I have tested in Ubuntu 26.04:

1. Connect the GC-01 to Linux PC with a USB data cable.
2. Power on the device holding the power button until the red light turns on.
3. Run the script: ./autoflash.sh <path_to_the_firmware.bin>
4. Wait until the script finished.

autoflash.sh

Usage log example:

user@pc:~/Downloads/radpro-3.1.1/fnirsi-gc01_apm32f103rb/firmware$ ./autoflash.sh ./radpro-fnirsi-gc01_apm32f103rb-en-3.1.1.bin 
Waiting for the 'BOOTLOADER' device to be plugged in and auto-mounted...
========================================================================
Device found!
Target Mount: /run/media/anton/BOOTLOADER
Firmware:     ./radpro-fnirsi-gc01_apm32f103rb-en-3.1.1.bin
========================================================================
[1/2] Executing first copy (Erasing flash & initializing virtual FAT)...
[2/2] Executing second copy (Writing actual firmware payload)...
Flushing OS write buffers to the hardware...
========================================================================
Success! Flashing complete.
You can now safely unplug your device.

Consider to include modification of this script to the distro.

i had made this before but apparently i forgot to post on this repo. should be much more reliable. copying twice fails for many users.
