MacOS drivers for STM32 bootloader (blue pill)

Development Tools IDE 1.x
1

I went through the following so far:

programmed the STM32 USB bootloader generic_boot20_pc13.bin into the blue pill.
I cannot see any STM32 related boards. From my understanding I first have to install the Maple drivers. I found instructions for Windows but lacking those for macOS.
To add some observation:

connecting the blue pill creates a device

crw-rw-rw-  1 root   wheel           22,  10  3 Nov 11:51 tty.usbmodem141301
crw-rw-rw-  1 root   wheel           22,  11  3 Nov 11:51 cu.usbmodem141301

and lsusb gives:

Bus 020 Device 027: ID 1eaf:0004 Leaflabs Maple serial interface

Looks like everything is there? Only I cannot add any STM32 boards in board manager. Funnily the entry at Port /dev/cu.usbmodem141301 is named "STM32 Marple bootloader". What has Miss Marple got to do with this? :open_mouth:

Seems I found the solution:

go into preferences, add additonal Boars URL:
http://dan.drown.org/stm32duino/package_STM32duino_index.json

The go to Board Manager and type in the search field "STM32". STM32F1xx gets listed. Install it.

Answered with the solution myself:

go into preferences, add additonal Boadrs URL:
http://dan.drown.org/stm32duino/package_STM32duino_index.json
Go into tools->Boardmanager
Enter STM32 in the search field
Choose STM32F1xx/GD32F1xx boards
Choose latest version,
Install
Go into Boards and choose Generic STM32F103C Series

Only programming seems to fail. When uploading a small blinky app, I'm getting:

dfu-util 0.8
dfu-util: Invalid DFU suffix signature

dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!

In the boards.txt file should be correct DFU signature for the board. Unfortunately, I am not in my PC now and can't look to my boards file

I'm inclined to think it's a dfu-util issue. Version or command line invocation and parameter passing. One could use another programmer, STM32CubeProgrammer. But how to set up the configuration for this I don't know.

I modified the maple_upload script and disabled the dfuse_addr parameter to being empty, being a dirty hack though.

#if [ $# -eq 5 ]; then
#    dfuse_addr="--dfuse-address $5"
#else
    dfuse_addr=""
#fi
