Question
OctoSPI not working on STM32U5
Hello, i am trying to communicate with an MRAM memory (Micron) via octoSPI but i can't manage to make it work! i already looked at the ST code examples and i got the same configuration as the examples but it just doesn't work. Please help!
PS: i am using OSPI1 on a Flash memory and the OSPI2 on my MRAM.
