STLINK-V3SET connection to STM32MP157C using CubeProgrammer

GHers.1
Associate II

hello,

I am connecting the STM32MP157C to the debugger using STDC14 CN1 connector in JTAG mode.

Please tell me the pin/signal direction, with regard to the debugger, for the following:

Pin 4, T_JTMS

Pin 6, T_JCLK

Pin 8, T_JTDO

Pin 10, T_JTDI

 

The connection fails using the CubeProgrammer.

I get the following message: "ST-LINK error (DEV_UNKNOWN_MCU_TARGET)".

On the debugger the PWR led lights green and the COM led lights red.

The signals I am using to connect are: T_JTMS, T_JTCK, T_JTDI, T_JTDO (STM32MP157C to debugger) and also providing 3.3V to pin 3, T_VCC and of-course connecting the GND pins.

I am not connecting STM32MP NJTRST pin to pin 12, T_NRST in the debugger (the STM32MP has an internal PU on it).

The STM32MP157C boot mode is JTAG (although doesn't work in USB boot mode).

 

What am I missing here?

 

thanks

Gil

Hi @GHers.1​ 

With ST32MPx products (MPUs), the JTAG is only used for debugging, so cannot connect to CubeProgrammer. CubeProgrammer connect using USB.

Debugging with JTAG is using CubeIDE.
