STM32H7 Hard Fault when RCC at 165 MHz

2021-06-28
I have the STM32H7B3I-DK (MCU: STM32H7B3LIH6Q), and I am trying to get the sys_ck close to its maximum frequency of 280 MHz, by running HSI or HSE through PLL. The trouble is that I can only get up to 164 MHz. Any higher and I get a hard fault. Is th...

I have a board (MCU: STM32H7B3LIH6Q) that I've been trying unsuccessfully to connect to using an external J-Link module, and recently I've switched to the internal ST-Link debugger. However, when I try to connect on STM32CubeProg for software reset, ...

Can't connect to STM32H7 board

2021-06-15
I've been working with the STM32H7B3LIH6Q board on Segger, and it was functioning normally until I happened to flash the code below to it. Now I get "no idcode detected" on Segger and "No debug probe detected" on STM32CubeProgrammer when connected to...

Can't connect to STM32H7 on SEGGER or JLink
