Hi ST!I am working with Rust on your STM32MP157. While we have this working already, this is cumbersome as we have to figure all register addresses and layouts manually. Normally, in Rust, we parse the SVD file corresponding to a chip and go from the...
ST provides eMMC partitions (besides fsbl and u-boot) : boot, root, vendor, user.I need new partition /home and want removing vendor partition.How can I get this customization ?
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...
