Not able to load ont on NUCLEON-H743ZI2

[Stijn Willems]

Thanks for the good explanation and setup. I managed to get a board NUCLEO-H743ZI2 like described in the readme.

My toolchain is set to

xcrun -f swift
/Users/stijnwillems/Library/Developer/Toolchains/swift-LOCAL-2020-02-15-a.xctoolchain/usr/bin/swift

When I try to run openocd it fails

openocd -f board/st_nucleo_f4.cfg

But as my knowledge is not big on the openocd part I got opened a new therminal and tride to load the builded blinky in to the

xcrun arm-none-eabi-gdb .build/debug/Blinky -ex 'tar ext :3333' -ex 'load'

So unfortunatly I am somewhat stuck now. Could you point me in a direction to look for a solution?

steps I took to get it working where installing the STM32 cube programmer on macOS Catalina. This was not trivial finally got it working https://community.st.com/s/question/0D50X0000BmnqrBSQQ/how-to-run-stm32cubeprogrammer-on-macos-catalina-10151-19b88

clue is to have the jdk 8 installed and using the .exe as instructed in link above

Still I cannot yet flash a simple program on the arm processor. Would appreciate any help but getting closer to solution :)
