Hello, I've been battling with this issue for a while now and I'm hoping someone has done something similar that can help with my issue.I have a STM32H745 board with an IMU connected. I'm accquiring the data over the M4 core and then trying to send i...

Hi, I have a custom board based on the STM32H745 and I'm trying to understand an issue I'm experiencing with the SPI Interface. I have a BMP280 attached to SPI1 on the M4 coreand I've successfully written a driver for it both using DMAs and Interrup...

I have a hobby project where I'm looking to design a flight controller using the STM32H745 microcontroller. My plan is to use the M4 core for data acquisition while using the M7 for the flight control stuff. I have a custom PCB with sensors connecte...

Hi, I've come across a few of these issues namely here but I haven't found a fix for my issue yet. I have a custom PCB based on the STM32H745ZIT6 chip which I wired up to be powered using the LDO power supply. However, I'm running into two problems a...

I'm trying to setup a GPS sensor (UBlox Max8Q) with a H745 Nucleo board using UART DMA using STM32CubeIDE. However, I’m having problems with setting up my board properly. My plan is to eventually do all my data acquisition on the M4 chip and do compu...

That did the trick, thanks! Still not sure why it worked on the M7 core though.

Hey, did you ever find a fix for this? Currently going through this as well

I managed to figure it out. I generated the same project for a h745-nucleo board which I'd modified for LDO and that worked fine. Turns out I just needed to change the power supply for my PCB. For some reason, the clocks won't initialise with this po...

Yeah, I initialise DMA before using either of the UARTs. I'm using USART3 without DMA and that;'s working without issues. UART4 RX is on PD0 while TX is on PA0 which is correct according to the datasheet. So I'm a bit stumped as to what may be causin...

That fixed it. Cheers!
