STLINK-V3MODS can't work with STM32H7

[DrDro]

Hallo,

until now we have used STLINK-V3SET connected with MIPI10 to custom evaluation board based on STM32H743.

For next custom board we need cost efficient debugger solution, just like STLINK-V3MODS

But it seems not to work together.

MIPI10 connector using CN5 pins 3..12 should be compatible with MIPI10 on V3SET.

V3MODS can detect correctly board voltage but nothing more.

Info : STLINK V3J13M4B5S1 (API v3) VID:PID 0483:3753
Info : Target voltage: 3.341772
Error: init mode failed (unable to connect to the target)

Pins on our board look like follw:

Is the V3MINI or V3MOD compatible with H7 series?

Hi,

klaro.

I have STLINK-V3MODS connected  to a H743 board - works fine (since > 1 year).

I just soldered some wires to the edge connector .

Where did you connect it ?  (MIPI connector not connected on v3mods !)

My debuger is MB1467B and looks like V3MINI but it is detected as V3MODS:

Bottom side of my debugger is equpiied with CN5 connector:

My board is as in ds , no cn5 - just the (not full) connected pads ;

cubeProg:

So check : are all pins of this cn5 connected to the edge connector ?
