You can transform st-link in j-link  https://www.segger.com/products/debug-probes/j-link/models/other-j-links/st-link-on-board/
But I haven't used any stm32 "clone", I don't know for sure if it will work for Geehy APM32F407VGT6, but you can test.

I've just tried that and it reports no J-Link or ST-lik connected even though it is and I've pulled high the BT0 pin
That's the problem I've tried STM32 Cube and ST-Link software but both report NO ST-LINK detected on ST-LINK and no DFU on ST-Cube, Not sure if a boot loader is installed on these boards.

This the link I clicked on the wrong one and not did not notice

UPDATE: I've found what can upload program to it just carrying out some testing, Lets see how it goes

You cannot use the programs from ST, you must use the software from Geehy.Geehy DFU Programmer is used for DFU upgrade of APM32 series MCU.

After you have converted a st-link to a j-link, for example from a Nucleo development board from ST, you will use the j-flash software from Segger to program the mcu, not the software from ST. You will need to  connect the boards to be able to program.

Update: Yes, use tools from Geehy.

I've tested tested with 2 units one connected to can hacker (transmitter) and the other one connected to P-Can view (receiver)  and played back some data that I've recorded.

And I can confirm it and it all works perfectly

if you are referring to F405/F407, the following devices (despite different naming) are using the same chip DIE so they are equivalent:

...

the same is for the F042 variant: the following chips mount the same chip DIE:

Am curious - where do you find which die is for which chip?

[digitalmg]

Very simple, in CubeMx create a new project depending on the MCU, and then select the family series,
for example STM32F4,you order them by frequency, and those that have the same frequency have the same pattern.
Or you can find it in the attached file.

as I first wrote:

Please also take a look to the following link (use google translate):
https://www.mikrocontroller.net/topic/459746?_x_tr_sl=de&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp&_x_tr_hist=true
here is the list generated: same DIE for several different CPUs!!!
see attachment.

Attached to the post there is an updated list of DIEs/CPUs directly extracted from the ST official files with the following command:

Code:

The source files are now in ./db/mcu and I created the file with:

grep -o "DIE..." STM* | sed -e "s/\(.*\).xml:\(DIE.*\)/\2  \1/" | sort
