Segmentation fault on STM32F103C8T6

[machadothi]

Hello everyone!
I'm getting a Segmentation Fault when I perform a st-flash command, running on Fedora 34.
I already tryed to install it by downloading the repository:

• $ sudo dnf install git make cmake libusbx-devel (libusb-1.0-0-dev Ubuntu)
• $ git clone https://github.com/stlink-org/stlink
• $ cd stlink
• $ make
• $ cd build/Release
• $ sudo make install

And also using 'dnf' command:

• $ sudo dnf install stlink

Error output:
$ /usr/local/bin/st-flash write main.bin 0x8000000
st-flash 1.7.0-77-ga52e1bc
make: *** [../../Makefile.incl:134: flash] Segmentation fault (core dumped)

@machadothi Can you try run the /usr/local/bin/st-flash --debug write main.bin 0x8000000 and post log?

[machadothi]

Sure! Here it is:

Let me join the party with #1165

@machadothi This problem occurred after @rewolff move chip information to files. The problem may be solved by using stlink_chipid_get_params_old instead of stlink_chipid_get_params.

@rewolff @machadothi "segmentation fault" is probably not the best way to handle an error condition?

[rewolff]

Of course! Segmentation fault is the system's way of saying "You screwed up badly and I can't proceed from this situation".

So instead of just terminating the program, it at least tells you SOMETHING.

Consider a big hall with (open) PO boxes. So you're doing a quest of some sorts. So your first assignment is go to box 123 and read the instructions. So box 123 has a note that says put this note in box 124 and proceed to box 12345. But when you walk to the end... you find that the boxes only go up to 9999.

So that's what happened: the computer got told to put (or get) something in a box that doesn't exist, or to continue getting instructions from a box that doesn't exist.
