i have a blue EVAL board (STM32H735G-DK) that I think stopped working.There is a ST-com LED that starts green but changes to RED and stays that way. The driver shows up on COM 3 in device manger. The STM32CubeIDE that I use does this at time but this...

I'm using HAL with stm32 (H735) and I use SPI5 and SPI4. Both are set up for DMA transfers. The SPI5 works fine and returns data from peripheral to ram. The data out is static, so all good. SPI 4 has changing data out but its not changing. Seems it ...

I have a st chip (HT35) with the STM32H735G-DK Discovery Kit. Projects was complete and running fine. We then had to remove the OCTO SPI nor flash chip because we need access to Pe2. but after removing the chip the app froze after MX_TIM4_Init(). The...

I tried to enable spi 1 and I get this, but everything seems to be configure?

I have a project where I want to add a simple PWM. I'm using the stm32h series. I have a scope on PA3, and I set up my timer2 for PWM on channel 4. I did this all in the IOC file as I want to understand how to create the PWM I need. I see it added my...

yeah but I can power up the whit board and jump the 3v3 from the output of that chip to the output of the other and it works.

setting to STLK give the red light and no 5v. but setting to fsusb and using a cable to cn14 works. But in both cases I can not program.with the fsusb I get thisif the board ST link is burned out, can I use an external st0-link to program? If I rem...

"The LD5 green LED turns ON when the voltage on the power line marked 5V is present. " its Red... and I checked a few points, there is no 5v..Maybe the 5v regulator is bad? I could supply it from another place for a test but not sure that is wise. I ...

I also have a white board Nucleo, I tested it with the same cable and it works. I think maybe the blue board has a problem but unsure what. The power config says ST.

Data with stm32 dma SPI does not flush?

removing chip cause unexplainable artifact.

- Main Config: These peripherals still have some not configured or wrong parameter values: clock

I cant seem to make a pwm work.
