Can M4 write to part of Bank 1 when M7 code is running from Bank 1? Idea is to define apartition at the end of Bank 1 and M4 write to it while M7 reads from it. I know thisneeds some tweaking of the dts to assign both Bank 1 and Bank 2 to M4 as below...
Hi, I am working on a project with the STM32H730. In order to make full use of the onboard memory I have the project set up to load some objects into DTCMRAM. This works, however the binary size is huge, like 403 MB, and subsequently is crashing cube...
Hello,I've configured SPI1 on STM32H742VIT6 connected to pins PA4-7 using AF5.Here is a dump of the relevant SPI1 registers:SPI1->CR1 = 00000001 SPI1->CR2 = 00000000 SPI1->CFG1 = 70000007 SPI1->CFG2 = 20400000 SPI1->SR = 00001002The MCU should be...
Hello,I'm having issues with software behaving inconsistently and freezing when I add certain lines, try to access certain variables, etc. I suspect maybe it has something to do with the restricted flash regions in the MCU. Is there any way around ...
So, this is a weird one. We're attempting to bring up watchdog timers on both cores of our product.We're not seeing the CM4 WWDG watchdog fire when we intentionally lock the CM4 in a while loop with no refreshes to the watchdog timer. (I haven't trie...
Hi,I'm using H723 for programming,and TCM ram is in use.when compiler optimization feature is on,code can not work.Is it not possible to use TCM while turning on optimization? or requires some setup? Regards,Binge
Hello friends, i have the following setup:STM32H725ZGT6 on a selfmade board. STM32 CubeMX (default program with HSI clock and without any other peripherals). Keil µVision 5.23ULINK2 Debugger problem:I can program the controller ("verify successfull" ...
Hello, I am trying to install FileX + LevelX in an stm32h7 microcontroller using a nor custom driver. I do have in my hardware an AT45DB641 NOR memory. I am working it as an stand alone and also with fault tolerant enable. My flash chip does have 40...
If DFSDM uses internal parallel data input, such as direct write to input register or DMA writing, what is the maximum frequency of input data in this application?
Hello all, I was trying to follow the example in MOOC - STM32H72x/3x hands-on workshop - 6 Code execution from external FLASHI have configured the OSPI as per the board requirements in CubeMX. But the `OSPI_Init()` function fails while trying to read...
