NUCLEO 144 H7 LEGACY for programming an external MCU

[shyammurali]

Dear ST team,

I am planning to use STM32H753ZIT6 in my design and also planning to use NUCLEO 144 H7 LEGACY for development activities. Could anyone help me whether I can use the NUCLEO 144 H7 LEGACY board to program the STM MCU which is going to assemble in my board? If possible please let me know how to isolate the on board MCU which is present in the NUCLEO 144 H7 LEGACY board.

Regards
Shyam

My stand point: 

To my knowledge, the NUCLEO 144 boards having STLINK V2 have been deprecated from awhile for H7 MCUs. The boards now feature STLINK V3. So if you purchase the board from a distributor (unless they do have V2 in an old stock).

If you need a STLINK V2  on a NUCLEO 144 board (that you can use it externally) you can purchase NCULEO-F439 (Not H7 product:(

Hi @Andrew Neil , @mƎALLEm ,

Thank you for the support earlier.

My MCU is designed for working at 3.3V, Is this voltage compatible with the ST Link programmer?

I want to know whether I need to put any level translator in between for SWDIO, SWCLK, SWO, VCP_RX, VCP_TX, NRST signals and the programming connector if 3.3V is not compatible.

Regards
Shyam

That's another question.

You need to post it in a separated thread and Accept as Solution the post that answered you original question.

Thank you.
