Re: [H743VIT] Custom variant attempt clock speed issue

Yes I do use a custom variant but it was not a supported board so I used the Nucleo H743 as base for the variant since it was the same chip.

I still have some clock issues but the main one is fixed. The peripheral clocks are still wrong like for canbus but I think I can solve them.

Re: [H743VIT] Custom variant attempt clock speed issue

That was not the problem but it was in the right way This piece of code was the culprit // HSE default value is 25MHz in HAL // HSE_BYPASS is 8MHz #ifndef HSE_BYPASS_NOT_USED #define HSE_VALUE 8000000 #endif HSE_BYPASS_NOT_USED is not defined and HSE_VALUE must be 25000000 since the crystal on this ...

Re: [H743VIT] Custom variant attempt clock speed issue

It didn't work. Still a 3.2 ms pulse. Serial is also to fast. I use it at 115200 baud but the monitor needs to be at 368640. F_CPU also raports a wrong value of 153600000

Re: [H743VIT] Custom variant attempt clock speed issue

After updating to the latest git version I still got the issue. The board that I use is a MCUDev DevEBox STM32H7XX_M board with the H743 This is the SystemClock_Config code that I use. void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = { 0 }; RCC_ClkInitTypeDef RCC_ClkInitStruct ...

[H743VIT] Custom variant attempt clock speed issue

Hello, I am trying to create the variant STM32H743VITx but I am stumbling on a really weird issue. The clock is setup to be 480 Mhz and when I toggle a LED with a delay of 10ms in STM32CubeIDE it really shows 10 ms. When I try the same in Arduino it is 3.2 ms. I copied the SystemClock_Config from th...
