I am looking at strategies for updating flash over CAN for the F446 (STM32F446RET6). A small loader program resides in addresses 0-0x8000, and loads the addresses above 0x8000 while there is other CAN traffic running. (This has been done and works wi...
Hello.Has anyone successfully read data from an SD card using CMD18 ( READ_MULTIPLE_BLOCK ) SDMMC in STM32U5?... or ... Can anyone confirm that these microcontrollers have a manufacturing error in SDMMC operation?IDMA from SDMMC reads data into the ...
Hi,We have some problems with booting a mcu (stm32g070), we have custom hardware.i can generate a mxcube project that works fine, every time a power the mcu on the custom hardware. this works onall pieces which we have producedWe created a project (t...
I know in some peripherals, like in a lot of times, the external clock is resynchronized to the CPU clock.In an ADC, that could add jitter. Does anyone know if using an external sample clock on a SAR ADC will be resynchronized to the CPU clock or wil...
In the datasheet of the stm32l053x in the section of "Memory mapping" it says "Refer to the product line reference manual for details on the memory mapping as well as the boundary addresses for all peripherals."I looked at the reference manual and di...
Well, I'm developing a system for reading sensors and sending them to a server.I'm using a GSM LTE module to do this sending. At first it worked well, but after a while the system stopped sending messages to the server.We can see this clearly in the ...
I've successfully set up an evaluation project on the STM32U5A9J-DK PCB with a custom 640x480 MIPI/DSI display in video mode. I've also configured the HexaSPI PSRAM in memory-mapped mode at 160MHz, which I've verified with a scope. My memory tests ha...
hello forumI've been playing with a H747I-Discovery board, and I want to add some more functionality to a combination of example codes - activating one of the i2c.the example itself doesn't include an .IOC file.As I see it I have two options:1.Start ...
Hi @Tesla DeLorean ,I use the IS25LX064 OctoSPI Flash memory with the STM32H573 and i can write and read from memory using direct mode. In memory mapped mode i can read the flash correctly for 0x90000000 but writing at 0x90000000 using memory mapped ...
(Spotted by sx107.)I know the subject is not very descriptive, but a figure is worth 1000 words:It's also in other 'H7 RMs; I leave it to ST to check them all :)(Btw. this is a carryover from the 'F7 RM, where both OTG's SOF indeed feed into TIM2 ITR...
