Using HAL and CubeMX. APB2 72 Mhz. The timer prescaler is 0, the period is 5, the duty ratio is 50%. How to solve this problem?

I work with stm32f405vgt, voltage 3.3 V, Cube MX ( version 4.27, HAL library - STM32Cube FW_F4 V1.21.0), sdio sd 4 bit widebus, fatfs, without dma, All CLK 18 MHz. I can’t mount the disk, open the file and write to the file. Attached is a schematic ...

pin clocks another chip. everything is stable, everything works, mcu is not reset. The problem was different, the pin speed was low, but needed medium. It is strange that when low everything worked at 3.3 V

Hello. We use stm32f405 and voltage 1.9 V. At this voltage, timer 8 does not generate PWM at a frequency of 12 MHz. At a voltage of 3.3 V, the generation works.

Hello. Can you give me please a sample project with fatfs and sdio for TrueStudio?
