21:32 <isaacgt> Hello,

21:32 <isaacgt> I'm trying to use OpenOCD to program a Tiva TM4C123GH6PM microcontroller using a ST-Link V3 MINI. OpenOCD successfully programs the microcontroller

21:32 <isaacgt> through a ST-Link V2, but the V3 MINI does not work. I have tried with version 0.11.0 obtained through Homebrew and with building STMicroelectronics's fork

21:32 <isaacgt> (https://github.com/STMicroelectronics/OpenOCD) and I haven't seen a difference between them. I'm relatively confident that I have the connections right since I

21:32 <isaacgt> determined the V3 MINI connections from the equivalently named signals on the V2, but I'm not completely sure hardware issues can be ruled out

21:32 <isaacgt> More information:

21:32 <isaacgt> - System: macOS 11.6 on x86_64

21:32 <isaacgt> - OpenOCD versions: 0.11.0, 0.11.0-rc2+dev-00039-gff701ce82 (this is the STMicroelectronics fork)

21:32 <isaacgt> - OpenOCD command invocation: `openocd -f /usr/local/share/openocd/configs/tm4c123gh6pm-stlink.cfg -c "program telemetry-board.axf verify reset exit"`

21:32 <isaacgt> - Config file contents:

21:32 <isaacgt> ```

21:35 <isaacgt> Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.

21:35 <isaacgt> Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD

21:35 <isaacgt> Info : clock speed 500 kHz

21:35 <isaacgt> Info : STLINK V3J3M2 (API v3) VID:PID 0483:374E

21:35 <isaacgt> Info : Target voltage: 3.293023

21:35 <isaacgt> Examination failed, GDB will be halted. Polling again in 100ms

21:35 <isaacgt> Info : Previous state query failed, trying to reconnect

21:35 <isaacgt> Error: jtag status contains invalid mode value - communication failure

21:35 <isaacgt> Do you have any advice on how to use OpenOCD with a ST-Link V3 MINI or how to debug this issue?

22:55 <karlp> isaacgt: iirc, stlink v3 (unlike other stlinks) simply blocks talking to non st targets.

22:55 <karlp> so there's simply no path forwards other thanto use your available channels to complain to ST about this step

22:58 <isaacgt> Well that's disappointing, but thanks for the help
