I'm using the bootlin buildroot branch: st/2021.02.I want to run a certain function on init of the Uboot (board_init function), like the ones used for the DK1 and DK2. My problem is that the function doesn't seem to be called. I have tried to debug t...
Hello, i'm trying to use M4 kernel from A7 kernel worked under linux.I've started with openSTlinux distro and it works well (i can upload firmware to M4 using rproc), but for some reasons i need to make a very small distro (less than 16 mb). For this...
Hi,I'm working the stm32mp157c som and trying to boot external quad spi flash (cypress S25HL512T). I added this to dts. &qspi { pinctrl-names = "default", "sleep"; pinctrl-0 = <&quadspi_pins_mx>; pinctrl-1 = <&quadspi_sleep_pins_mx>; status = "...
Looking at the clock in the MX Device Configuration Tool it says 204 to APB1 Timer Clocks (MHz).To get to 10000 Hz I have to divide 204 MHz by 20400. Fortunately there are a bunch of ways to do this. But on the first try I tried Prescaler 51Counter ...
Is there any plan to release C++17 compatible HAL and LL libraries for MP1 platform? I had written a lot of code in C++17 and later found out that MP1 libraries are full of `register` keyword which is not supported since C++17. A temporary solution i...
I've enabled pps-gpio and pps in the kernel config and added the following to the device tree:/{ //... pps{ compatible = "pps-gpio"; gpios = <&gpiod 13 GPIO_PULL_UP>; status = "okay"; }; };but this results in the follo...
Good day,Has anyone been able to compile Azure Sphere OS for the STM32MP157D-DK1.I have the yocto environment configured, and I am able to build a vanilla embedded Linux image, but when I add the azure bblayers to the build. the build fails. I also t...
I have custom stm32mp1 board and when running it as USB mass storage in U-Boot (ums 0 mmc 0), the USB driver is not detected nor by Linux nor by Windows. I am also attaching shematc comparison of eval-board VS my custom board. Also the USB-ORG is wor...
In previous releases of OpenSTLinux, u-boot used the NAND DFU backend to write to the NAND flash in the EV1 dev board. For UBI images, this required that the image was generated using the --space-fixup flag.To avoid this requirement, I submitted a pa...
I am enabling SPI1 controller and selecting PLL3Q as its kernel clock source on CubeMX. But automatic code is not generated for it.It looks like #DEFINES for SPI1 do not exist in stm32mp1-clksrc.h, while they do exist for other SPI controllers.
