STLINK-V3MODS for STM32MP1 Compatibility

[mhd0425]

Hello,

I am in process of designing my own STM32MP1 powered device. I was wondering if I can use STLINK-V3MODS as a drop in replacement for ST-LINK/V2-1 in STM32MP157-EVAL reference design. I need the Virtual COM interface embedded in device.

Hi @mhd0425 

Although I guess STLINK-V3MODS has not been specifically tested on STM32MP1 devices, all STLINKs flavors are compatible with STM32MP1 (assuming VDD=3.3V).

If you are interested only in Virtual Com Port, and depending on amount of product you will product, maybe there could be some cheaper solutions:

• use a cheap STM32 part to do only UART/USB bridge (I guess USB full-speed would be enough for VCP)
• use a dedicated UART/USB bridge component or cable (e.g. FTDI chips/cables)

For debugging, providing an STDC14 (or other) connector on your board would allows to use any external debuggers (STLINK or other) during development phase.

Regards.

Thank you @PatrickF this is exactly what I needed.
