STM32Cube_FW_H7_V1.3.2 migrate to STM32Cube_FW_H7_V1.8.0 give problems with SDRAM, FMC and LTDC ...

[hjh]

Hi

I did buy a https://www.waveshare.com/wiki/OpenH743I-C and they provide some sample codes...

They are all made in STM32Cube_FW_H7_V1.3.2 and works fine when i do compile in Stm32cubeide.

BUT ...when i do say MIGRATE to STM32Cube_FW_H7_V1.8.0 i got problems with LTDC, SDRAM and FMC.

Nothing happend on the screeen and it seems like i got hardware failure when trying to write to 0xD0000000 whitch and the FMC bank 2 as the SDRAM are connected to.

Do anyone have a glue ...WHat have changed in HAL drivers files from 1.3.2. to 1.8.0 ?

Thanks

Hjalmar

I also have an issue on H743 with SDRAM and suspect its the H7 firmware 1.9 causing it as its very odd behavior and have it working on an older verion with a F767 with the same config for the SDRAM and same clock speed (confirmed by scope). I posted elsewhere but wondered if you resolved this or found the fault?

Thanks,

Mark
