OpenMV H7 on NUCLEO-H743ZI board

Postby zoxno6 » Thu Oct 04, 2018 4:01 pm

Hi,
I have an NUCLEO-H743ZI with STM32H743 144 pins controller development board ( https://www.st.com/en/evaluation-tools/ ... 743zi.html ). I'm trying to install openmv4 firmware on it but without success. Will somebody help me?

We don't support that board. If you want to try to use our firmware on it you need to understand what you are doing.

On which MCU is based OpenMV H7 board? Which is frequency of quartz crystal on H7 board?

It's the STM32H7VIT6 with a 12mhz crystal.

@zoxno6 Hello how are you uploading the firmware to this board?

@kwagyeman Do you support uploading your firmware to other opensource boards ie Nucleo? or even if we copy the SCH and make our own PCBs based on openMV HW design?

We don't support the Nucleo. If you want to try to port our code to one you can. Its more work than it's worth however.

That said you can port the algorithms rather easy.

I upload successfully openmv4 firmware on Nucleo-H743ZI using STM32 ST-LINK utility, but PC ( OpenMV IDE) not see OPENMV - usb communication not work. I think it's because I do not have a camera sensor attached to Nucleo.

Yeah, the firmware panics if it can't find a camera.

Dear victagayun , thank you for suggestion. For this module, I would have to make an adapter for the Nucleo Board. But the guys from OpenMV LLC gave us all the necessary files to create their hardware! I think I'll wait for the OpenMV H7 to go out for sale.
