Hi,We are using Stm32mp157a processor and uboot2018.11 version.We have QSPI interface to NOR flash. We want to write,Read and erase the Data in Qspi Memory(i.e,Nor flash).We want to boot the image from Nor flash,How can we do that ?Thanks in Advance.
Hi,We are using stm32mp157a processor and we are working on uboot-v2018.11 at Linux side. I have an idea on board-debug-uart_init().Path for board_debug_uart_init().Path :board/st/stm32mp1/board.cIn board-debug-uart_init() .We have only UART_TX infor...
Hello, my main seriale console should be USART2 instead of UART4. I modified the kernel dts as follows: chosen { stdout-path = "serial0:115200n8"; }; aliases { ethernet0 = ðernet0; mmc0 = &sdmmc1; mmc1 = &sdmmc2; serial0 = &usart2; ...
在根�?�ST�??供的tf-a编译阶段，为什么我使用make -f Makefile.sdk TF_A_CONFIG=trusted TFA_DEVICETREE=stm32mp157c-dk2 all这个指令编译的时候会报下�?�这些错误？
I have attached an Adafruit LCD (https://www.adafruit.com/product/1770) to my STM32MP157D-DK1 on SPI5 (on the RPi header). I am working with Yocto and the STM32MP1 BSP (but not OpenSTLinux). I am attempting to modify core-image-minimal to enable the ...
On DK2, using devmem2 on linux I read that GPIOH->MODER/ODR (0x50009000/0x50009014) are all zeroes. The same for GPIOA. OTOH some other things can be read out like RTC clock settings. Is there a way to read the GPIO registers?
Hello, I'm designing a board based on STM32MP1 and it's my first time using QUADSPI.I need to boot on a NorFlash (MLO + U-boot), and my Linux filesystem will be on a NandFlash.Those constraint come from the fact that on my previous system (based on a...
We are trying to implement a KSZ8041FTL in an embedded design. We are using an STM32MP157 device in a SOC provided by Octavo systems (OSD32MP157C-512M-BAA). We have used design resources provided by Microchip and followed examples provided. We have f...
It seems that I have a problem with DMA, but I'm not sure. Would you please take a look at the below screenDts looksI intend to achieve MII with self-generated quartz.Unfortunately, I'm stuck on this "Failed to reset the DMA".
