I'm trying to edit the device tree of the distribution but there is no .dts or .dtsi files in all the distribution package directories. The only way I found to experiment modifying the device tree is doing it with developper package (I modified stm32...
My STM32MP157F-DK2 is powered by 5V 3A PSU. but at the boot up time, always it displays the warning ***************************************************** WARNING 500mA power supply detected ** Current too low, use a 3A power supply! *******...
I have successfully build st-image-weston using Distribution-Package.Now I want to add libmodbus to st-image-weston.I refer to the wiki page below.https://wiki.st.com/stm32mpu/wiki/How_to_integrate_an_external_software_package1) I checked the libm...
I am working with a custom board, and are using the CM4 core to configure and mange FPGAs via the FMC. In my system the FPGA configuration requires the transfer of a large data buffer (3MByte-10MByte) between the CA7 core and the CM4 core. I unders...
Hi,I'm working on STM32MP157A-DK1. By following this linkhttps://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package tried building the image for STM32MP157A-DK1 but i facing the error ERROR: icu-66.1-r0 do_compile: oe_runmake failed during build...
Hi, Everybody! Could anyone help with correct device tree for qspi-nand flash. I can't see any activity on pins connected to flash. If I try to boot from spi-nand with BOOT0..2 set to 1, I can see clear SPI transactions... So, flash connection looks ...
I'm connecting a X-NUCLEO-PLC01A1 with my DK2 card. The Inputs are working fine and for the outputs I can read the fault status , I'm getting 0000 0000 1000 0101, then all is right, the 3 error leds are off, and the OE signal is in 0 (I tested also w...
We are having issues with STM32MP157 UART7 (address 40018000) exiting low power CStop mode and waking up Linux (v4.19 from ST github).We have confirmed that CStop mode is entered, and it can be exited using an external interrupt (55 pmic_irq), howeve...
