ChibiOS Free Embedded RTOS

Hi,

Your ADC clock source (STM32_ADCSEL) is set to STM32_ADCSEL_PLL3_R_CK, is it meant to be that way?

Giovanni

Fixed thanks.

Hi,

Please post your mcuconf.h.

Giovanni

Good point, need to check demos, probably there is the same error and necessity for DSB is not explained at all.

Giovanni

Hi,

I think it is a good hypothesis, it would be possible to place temporary code and check the state of FIFOs before starting a transfer.

Giovanni

You need to determine how it stops, enable assertions and checks in chconf.h and then use the debugger to see where it stops and the cause.

Giovanni.

The code is the same, use 2 ports instead of one.

See the SPI demo in ChibiOS: testhal/STM32/multi/SPI it does mostly what you are trying to do.

I just started porting the whole trunk HAL to 21.11.4, it could take some time because all differences but what you see in trunk now is what you will get in 21.11.4.

Hi,

In the community repository there is an USB host stack that, I am told, works well.
