Hi!We are using mdma (dma0chan20) to do "memory to memory" transfers from the FMC to (user) RAM. The FMC is used to access a FIFO buffer that is filled by an FPGA (128kB size).Between individual DMA transactions we measure a delay up to 5ms leading...
Hello, teachers.I'm sorry in advance because I think I'll be talking too long.The board I use is STM32MP157D-EV1 (evaluation board).From the previous question and answer, I found that Ubuntu 18.04 and SDK could not be installed on my board, which had...
Hello, teachers.First, The board I am using is the STM32MP157D evaluation board.I checked the article that the starter package can be installed in Windowsos, but the developer package and the distribution package are only available in the Linux env...
I have a board from karo-electronics, STM32MP157c based QSMP 1570 SOM over qsbase2, I am trying to configure above mentioned board for my specific application, The distribution is build using yocto by karo-electronics, I am unable to edit the dts fil...
I even installed the starter package in EMMC boot mode.And I want to install a developer package.I want to install SDK, can I use STM32MP157D-EV1 board using STM32Cube Programmer in Windows OS?Ubuntu 18.04 was installed in virtualbox and STM32Cubepro...
I am using the STM32MP157D-EV1 board.The starter package is currently installed in EMMC boot mode.the version is "ST OpenSTLinux - Weston - (A Yocto Project Based Distro) 4.0.4-openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23 \n \l" .I need to install ...
Hello community,the errata says (in combination with the missfunciton of the delay block), that only modes up to DDR50 can be used with the STM32MP1xx.Actually we now have the problem, that writing to the SD card works well but the reading through th...
Hello,I have the stm32mp157c-dk2 board and have connected two CAN Bus transceivers to it.FDCAN1 is assigned to the A7 CPU and the FDCAN2 is assigned to the M4 CPU.Both transmitters are connected to the same CAN bus. There is also a 3rd device connect...
Hello, I have received a STM32MP157F-DK2 so I develop a program to send data through the SPI port toward other device (like a STM32 nucleo, maybe).Reading about this first device I saw that example code won't work there but I should use spidev on ope...
Hi!I am using STM32MP157C-DK2 and i want to start the coprocessor from bootloader (I have readed the wiki page). First, I have done it manually and everithing works fine:I have changed kernel m4_rproc:&m4_rproc{ /*Restriction: "memory-region" proper...
