1. I have modified the STMxxx_Flash.ld linker file by adding some memory sections. Does the sequence of SECTIONS definition matters? LinkerScript.ld and MPU Config Added.Layout:ITCM -> Has some functionsDTCM-> non DMA Global VariablesD1 RAM (First 2...
MCU: STM32H753VI Scenario:I am working on the error management system for our firmware. Part of that is handling ECC errors in flash and RAM. I have been able to successfully inject and handle flash ECC errors, but am having trouble with RAM ECC. Pro...
I want to test the code to handle SRAM2 parity errors, is there any way to force a parity error to test the code?When a write is made the 36 (32+4) bits are updated, is there a way to update only the 32 bits or the 4 parity bits?Or is it possible to ...
Hello,I have a strange issue with backup ram in F405. It is battery powered after main power off.When i remove battery and power up board, whole bkpram contains values of 0 - this is normal. But after initialize procedure whole memory contains random...
Hello, I have a quick question. I'm wondering if I can put the frame buffer in SDRAM connected via FMC when I use FMC LCD controller to controll Display that uses the same address pins of FMC.
I'm writing software on dual core CPU, On M4 core, I need to know is it support bit banding? I searched all documents from ST, but I didn't find clear answer, I found on M4 CPU, like STM32F series bit banding has supported, and on M7 single core CPU ...
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...
Anyone have some insider knowledge or just plain rumours of what chances are for ST considering releasing a STM32H7 with larger RAM in the near future?Like 3MB or larger, as some STM32U5’s have (I also just noticed some competitors having large RAM d...
Hi there, I am writing a custom video decoding app that process custom stream JPEG frames from USB, without any standard on a STM32H747.So far, (more or less) so good, I use CM4 for USB operations, and CM7 for JPEG decoding and DMA2D pixel conversion...
Hi, I'm developing a STM32H750VBT6 board that need SDRAM, the datasheet said that only LQFP144 package does not support SDRAM, but I cannot find SDRAM option in FMC configuration. Can someone please help me.
