I am using the STM32MP131 in a baremetal environment. Since there is no internal flash, I am planning to use external flash and DDR.I have confirmed that writing to and reading from the flash works, but I don't know how to start from FLASH instead of...
Hello,Would it be possible to have an updated guide on how to use a custom device tree within my own layer for latest STM32MP1 Ecosystem ?The one provided here "How to compile the device tree with the Distribution package" is clearly outdated, as th...
Hello,We're trying to boot our prototype which contains an STM32MP157FAA.Unfortunately, we didn't implement an oscillator/quartz on the board, so we are unable to use HSE and can only use HSI.We have access to USB1, USB2, SDMMC3, and UART4.Is there a...
HiI have recently been working on the board model mentioned in the title. At the moment I have a problem with two things:1. when trying to debug the kernel drivers, the kernel is inactive for a period of time which causes the watchdog to run. This be...
Hello to everyone!We have develop a System on Module board based on the STM32MP153AAB. Currently it have a custom Yocto Image build, that it's working. The process followed almost all the steps in the wiki for the STM32MP157F-DK2 discovery kit, howe...
I want to test the memory by using U-boot.I'm reading the DDR memory from 0xC0000000 to 0xE0000000 with the pattern 0xFFFFFFF. But I don't have premision to read the memory. How can I solve this issue? STM32MP> mtest 0xC0000000 0xE0000000 0xFFFFFFFF...
Dear All,I have been developing touch screen with XPT4096.When press touch screen, interrupt is generated.Read Y, X, Z1, Z2, power down is sent to XPT4096.During transferring message to XPT4096, transfer setup failed.Please refer to waveform.1CH : sp...
I can fix the problem by enabling interrupts for the DMA channel. But WHY should this be necessary?I'd prefer to do this with no interrupts. I allow ample time between calls so data transfers have plenty of time to complete.(G4 chip, MX set up as SPI...
Why does the STM32MP157AAD3 have a higher heat or temperature? We have an STM32 board that has interfaces for PMIC, DDR3, temperature sensors, VOC, EMMC, LEDs, push buttons, WIFI+BLE modules, 8-pin connectors, wake-up switches are build in same board...
Hi, we have a custom design with an STM32MP13xx CPU.We currently see random issues during boot. Some of the prototypes randomly stuck on boot without any output on the serial console, sometimes they are booting well. When a board has booted it runs s...
