Hello Team,We have a custom STM32H745 board designed and We are able to get the IC up and running on cube programmer and even set option bytes. The board is designed with Nucleo-H745ZI-Q schematics and we have verified everything on hardware end.When...
Hello Guys, We've our own board with STM32H743BIT6 mcu Integrated. We've tried to dump the code by using the external ST-LINK V3 Debugger with JTAG Interface. It works fine for first 3 - 4 times. But then after reaching the board for the 5th time ...
Hi STM Community, I want to ask if I have to Erase Flash memory sector (HAL_FLASHEx_Erase) before I write into flash memory (HAL_FLASH_Program)?I tried it and nothing happend. I want to be sure, that is not an accident.
I've successfully configured a 64Mbit PSRAM with the OCTOSPI peripheral of my STM32H7B0 microcontroller in Quad and memory-mapped mode, although according to another thread and the erratas of the OCTOSPI peripheral, I understand that you should only ...
STM32H735 using the RMII interface to the LAN8742 PHY chip. Right out of the eval board schematic, and it seems to work. USB also implemented in the usual way....and it works, until we turn on the LAN support in X-CUBE-AZRTOS-H7. Then the middleware ...
Hello I am using an STM32G491RcT6 processor, when I connect it with ST-link to CubeProgrammer the Write Protection section of the option bytes does not appear, if I connect an STM32G491ReT6 processor it does, Document RM0440 does not seem to me to re...
Hello there!I would like to ask for help from those who know this MCU family about the system memory bootloader. As specified in the AN2606 Rev64 document, section 41.2, after the System Reset the microcontroller checks the value of the nDBANK and nD...
Hi,I am working on STM32F302K8 and would like to use it's CAN Bus to communicate between devices both as master and slave It is my first time using STM32CubeIDE and the HAL library and implementing CAN Bus on my work. I did use some samples scattered...
Hello,Nobody at STM seems willing to answer my questions to the NUCLEO-H7S3L8 board. I've two of those boards and spend much time with them, but nothing will work. None of the examples from STM32CubeIDE can produce any results with those boards.I wro...
I have a bit of code as follows:str r3, [r0, #68]ldr r3, [r0, #68]where [r0, #68] is TIM20.BDTR on a STM32G474. I would expect that the LDR would output the same data that was just stored, however it seems that out outputs the previous data. I al...
