I'm using a STM32H753 with external RAM. We were using it for LCD framebuffer. Now we are trying to migrate the stack and heap to the external RAM, when we run the code, getting hardfault on lines where std::array is declared. Any idea on how to debu...
Hello everyone,I am currently working on a bootloader project for the STM32H735, using the pre-configured ExtMem_Boot project provided by the STM32CubeIDE. However, I am encountering an issue when trying to write to the external flash memory at addre...
Hi!I am writing a bootloader for an STM32H7S3L8, that received the application binary over UART and places it into flash, specifically on address 0x08008000, and I am getting hard faults when jumping to the address.If I "install" the application AND ...
Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send...
I have an issue when changing the option bit of STM32H742 to change the RDP level to 1.I read out option bit from register FLASH->OPTSR_CUR, change the RDP bits to eg 0xBB, write the result to FLASH->OPTSR_PRG and then set bit FLASH_OPTCR_OPTSTART in...
Hello everyone,I'm experiencing an issue with my STM32 microcontroller (STM32h745iik6 own board) where it doesn't execute the code upon power up. However, when I press the reset button, the code executes as expected. I'm looking for some guidance to ...
Hello,I'm a hobbyist and I'm working on a USB to 4xI2S (8 channels using the SAIs) using a stm32H7 MCU. I have a proof of concept working on a stm32F7 discovery board. I'm starting to look at the dedicated board.I understand that the USB peripheral n...
I'm considering using the internal PLL to generate a clock for a precision ADC. My sample rate is low, so it's possible this may work. I need less than 50 ps RMS phase period jitter.Looking in the datasheet at the specs for PLL1, I'm having difficult...
Hello,I am using the nucleo h755zi-q board on my project. I am having issues with getting the uart driver to work with the LL library. For starters I have the CM4 core disabled via the option bytes and am just working with the CM7. Code for clockConf...
Hello.I am developing a UART bootloader. Currently developing it on the Nucleo H7S3L8 that sports the STM32H7S3L8 microcontroller, 65K flash, ~450K something RAM.I have implemented the ol' JumpToApplication pattern that can be found all over the inte...
