Hello,I stumbled over a weird problem when trying to debug Memory Protection Unit (MPU) settings which I want to document here in case any other people have the same issue:SetupThe used MCU is a STM32H7S3L8H6 on a STM32H7Rx/7Sx Nucleo-144 board (MB17...
Hai All!I use 2 pieces of APS25608N PSRAM on OSPI bus with memory mapped mode. The MCU run at 1.8V, 160MHz system clock. Previously, I used APS12808N at 80MHz and 3.3V VDD without any issues.Currently, the PSRAMs run at 50MHz, but need to speed up to...
Hello everyone. I am trying to write a bootloader with STM32H750IBT6 and mt25ql512. I am trying to adapt the ExtMem_Boot example of STM32H750-DK to STM32H750IBT6 by modifying it, but I can't succeed. It doesn't make sense why STM32H750IBT6 does not w...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
When I write code, should I keep the microcontroller on, or turn it off and only turn it on when I want to test the code?
Hello, I am planning to use the STM32G474RET6 and would like to confirm whether I can use the internal VREFBUF. This product's package is LQFP-64 and while reading the datasheet I noticed the note : ''The VREF+ pin is double-bonded with VDDA on some ...
Hello,The datasheet and reference manual are missing information about the 4 KB Backup SRAM in the memory map.Where can I find details about it?We need to use this memory in both Secure and Non-Secure projects.Thank you.
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
Dear all,I'm trying to generate a waveform using DAC OUT1.I configured pin PA4 as analog (works)I configured DAC1 without DMA and it worksI configured TIM6 and it works Then I configured DAC with DMA, configured DMA, but output never changes.Where ca...
Dear allI am using STM32H563 and interface with some CAN bus sensors to receive and sometimes send data to them. The CAN bus sensors are developed by a partner company. I developed my software refer to FDCAN_Com_IT example provided in IDE firmware pa...
