Hi,I'm using stm32mp153c and I managed to start M4 code after the SPL initialization and before U-BOOT. All initializations work fine except for the MX_OPENAMP_Init.I see that if I start the code after SPL the variable of num_of_vrings (that is equa...
Hi there, I've got an STM32MP157F-DK2 devkit, I managed to set up all the packages, including Yocto distribution (Distribution Package) and all seems to be working fine for me. Now I'm starting to modify ST distribution, just to get used to the envir...
Hi there, I'm starting developing on an STM32MP157F-DK2 kit, and I wanted to build my own distribution, starting from the distribution package (STM32MP1 Distribution Package - stm32mpu). At the first compilation, the bitbake st-image-weston takes rea...
Hi, I have upgraded to Ecosystem 3.1.1 and have started to get warnings in TF-A when booting up my stm32mp151c. These are the warnings: NOTICE: CPU: STM32MP151CAA Rev.B NOTICE: Model: STMicroelectronics custom STM32CubeMX board NOTICE: Bootrom aut...
We are migrating from ecosystem version 2.1.0 to 4.0.0. We have a custom board with STM32MP157C.After resuming from STANDBY the ADCs and DAC, used by M4, no longer work. They are initialized and started without error, but all ADC channel data reads 2...
Imagine you are a newbie trying to understand the device tree and clock configuration.Which of these pages is more useful?https://wiki.st.com/stm32mpu/wiki/Clock_device_tree_configurationorhttps://wiki.stmicroelectronics.cn/stm32mpu/index.php?title=C...
Hi, I cannot debug stm32mp157-dk2 on macOS (stm32cubeide). I have those logs in the console:Does anyone know how to resolve it? :)
HiCurrently, I'm designing a PCB with "STM32MP151AAD3T".I'm developing our own PCB with reference to "STM32MP157x-EV1".DDR trace wiring is described in Section 3.2 of "AN5122" as follows:**************************************************************...
Hi,I am using stm32mp157a processor in my custom board. Fsbl and ssbl is booting from Sd card.When i try boot through Emmc it is not working,even files are not loading. I have followed below link for emmc booting https://community.st.com/s/question/...
We're using Ecosystem 2.1.0 still (I know!).I'm using the CubeMX autogen code i.e.rcc_pins_mx: rcc_mx-0 { u-boot,dm-pre-reloc; pins1 { u-boot,dm-pre-reloc; pinmux = <STM32_PINMUX('G', 2, AF1)>; /* RCC_MCO_2 */ bias-disable; drive-push...
