I'm trying wean myself off the STM HAL library and learn how to program peripherals at the register level. I'm starting with UART1 on a STM32H7A3. UART1 with Alternate Function 7 has TX on GPIOB pin 6 and RX on GPIOB pin 7. So I think I need to se...
Hello,I am working on the USB DFU for a STM32H7A3ZGT6I have two projects one for the DFU and one with the application to be updated.My application works fine when I download it with the debugger.The DFU part manages to erase and program the new app t...

Hey guys, I was wondering if someone made the onboard High Speed PHY to work on the STM32F730Z8? No matter what I have tried, I am not able to make it work on HS. I am trying to implement an MSC host to read a USB memory stick. It is working without ...
I have referred to this document but it gives no solution.https://community.st.com/s/article/how-to-enable-dma-in-usb-with-stm32h7-devices?t=1659888985140I have tried putting all the USB variables and arrays into a noncacheable region of AXI1 RAM but...
Posted on July 14, 2018 at 01:29Hi,what is the procedure to start the system bootloader in the STM32H743 via software. Even newest AN2606 is not clear on this, since none of the mentioned methods fit the STM32H7 registers etc.What I mean:For the F4 ...
I am using PyOCD and CMSIS Pack Manager to connect and read from my MCU. However, to write I need to know the specific MCU name such STM32g071cbux. Is there a way to autodetect that variation between like STM32g071cbTx. or can I auto detect like my p...
In the following HAL function, RTC ISR register is cleared by "Read/Modify/Write" instruction.Couldn't this cause eventual clearing of the ISR flags which may be raised by RTC periphery between "load" AND "store" ?If somebody can confirm that such si...
But it is normal to write single blocks continuously (cmd24), but the speed is a little slow. I use FatFs to write multiple blocks (cmd25) to SD card. I can only create a new TXT file, but there is no data in it. And when writing multiple blocks, the...
