I have a DK1 and have wired to UART7, and got UART7 working by grafting this section (by using the CubeMX tool latest version as of a few days ago) into the existing st32mp157d-dk1.dts and rebuilding. (The real product is intended to use UART7.)===al...
Hi,I am working with the STM32MP157c-DK2. All examples are working fine, but now I would like to use custom code. I generated some code using CubeMX for the development board. I used the default settings and enabled FreeRTOS additionally. I compiled ...
Im trying to integrate the firmware we have developed into our distribution on yocto. The documentation in the wiki [1] isn't really clear in how we add our own firmware to populate the MP1 coprocessor on boot. And the eample projects that the m4proj...
Hello,so I am using the Yocto environment and patched the device tree:diff --git a/arch/arm/boot/dts/stm32mp157-pinctrl.dtsi b/arch/arm/boot/dts/stm32mp157-pinctrl.dtsi index dd796ec03..54ef05294 100644 --- a/arch/arm/boot/dts/stm32mp157-pinctrl.dtsi...
Hello,I would like to enable battery/capacitor charging from the VBAT pin on an STM32MP1 and also change the charging resistor.That would be VBE and VBRS of PWR_CR3.What would be the proper way to enable/disable the charging together with the resisto...
I am currently building a dedicated image for our custom board based on STM32MP1. According to the wiki and OE mega-manual, I need to create a custom distribution to be able to customize it according to our needs.I am following the steps described he...
Hi, I've created a SD card following this guide. The generated SD card partitions can be seen in the screenshot here below. It seems to boot correctly until the kernel prompts the following error:[ 4.200445] ---[ end Kernel panic - not syncing: VF...
Hi, I am trying to compile an OpenSTLinux image for a target "DK2_A7" custom machine.I've followed this guide and everything seems ok until 98% of the process when the following error occurs:ERROR: tf-a-stm32mp-2.4.r1-r0 do_compile: oe_runmake failed...
Hi, I need to edit the "stm32mp1.c" file inside the uboot sources, in particular I have to set the following change on line 413:nb_blink = 4; How can I do that on OpenSTLinux (Yocto approach) ?Where is the file and how can I maintain such edit after ...
I have followed this guide in order to use custom DTS files (followed step-by-step) and the following error occurs, how can I compile without using the op-tee?ERROR: optee-os-stm32mp-3.12.0.r1-r0 do_compile: File /home/ubuntu/customer/openstlinux-5.1...
