We try to configure the (M)DMA in Linux device-tree for our System on Module board based on STM32MP151/7C but it always said us that it cannot configure it so we had to disable dma for memory (QSPI Nor/NAND and FMC Nand) which cause performance issue...
I want to connect a 128x64 LCD to my STM32MP157D-DK1 board and implement a program on the A7 core Linux to display some parameters. What should I do? Thanks in advance.
Do we need to compile CUBEMX dts files before bitbake or we need to convert them into the dtb files with eclipse like in this ST video and what is the best way to go from discovery board to custom board in the means of creating device tree files for...
I have a large firmware that the MCU must execute. It will not fit into SRAM1-4, so I am trying to move the entire code (or a portion of it) to DDR RAM. I have no problems reading and writing DDR memory from the MCU, as long as it's just data, but fo...
hi, i'm trying to make USB_FS work on my custom board. my desired configuration is peripheral (otg can be ok, i have jumper on id: PA_10)i already have 2 USB HS so i can use only USB_FS mapped on PA_11 and PA_12 as OTG. i follow the st wiki at the po...
I'm using a custom board (it is not DK1 even tho it says on boot log) with STM32MP157AAC. The boot hangs on u-boot without proper error message. Where should I start to search the failure? NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelec...
I have a custom STM32MP157c board. I try to set fuse bits (3 0x23000000). It worked on the basic boot system but not on the TF-A boot system. I mean by example the boot command : fuse prog 0 3 0x23000000.
Hi!I am using a STM32MP157C-DK2 board to create an application on the screen. I have used STM32CubeIDE to create my own program:I have initialized peripheral with its default modeI have enabled FDCAN peripheralI have changed the clock settings.With t...
