Cannot flash STM32F103C8T6

[MHof]

Hello together, I am beginner with STM32-controllers and I have started reading the tutorial book "Beginning STM32" from Warren Gay.

I ordered three STM32F103C8T6 platines and I have also three ST-Link V2 program/debug adapter, but only with one adapter I can at least communicate with any of the three STM32F103C8T6.

I am using Debian Linux as operating system on my laptop and I have connected like described the STM32xx with my computer over USB and the ST-Link V2 - adapter.

But if I execute the command "st-info --probe" I do not get all details of the controller:

root@MH1977:~# st-info --probe

Found 1 stlink programmers

serial:

openocd: ""

 flash: 2 (pagesize: 7)

  sram: 134273

 chipid: 0x0410

 descr: F1 Medium-density device

root@MH1977:~#

As you can see at serial and at openocd nothing is being outputted though the command has detected the controller. The other strange thing is that the flash memory size is only being noticed by 2!

By the way, I could read flash memory by executing st-flash read ./saved.img 0x8000000 0x1000. But after execution, the blinking yellow LED stopped blinking and only the red power source LED is lighting. I hope, I do not have damaged anything with that command?

Trying to write memory leads to following error:

I have the newest firmware at my used ST-LINK-V2 adapter (done by STM32CubeProgrammer) and I have executed the commands as root user.

I have checked the wirings of the adapter to the controller and verified several times.

Does anyone have an idea what the reason for these errors can be?

Especially as STM32-beginner I am looking forward for any help or advice.

Sincerely,

Marco
