Hi,I have a current project using the M7 that I need to port over to the A7. The goal is to be running bare-metal code on the A7, like we are on the M7. Currently, I am following this open source guide to run bare-metal on the A7 and it seems to work...
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...
I would like to understand why I cannot find and enable STM32 SPI support in the Linux kernel and resolve conflicting information in the Wiki articles I am using.When I use menuconfig, I cannot locate STM32 SPI support in the menu. If I use the searc...
I was trying to test the ADC of a STM32MP157C-DK2. I downloaded a basic example program to perform the data acquisition in the M4 processor (https://github.com/STMicroelectronics/STM32CubeMP1/tree/master/Projects/STM32MP157C-DK2/Examples/ADC/ADC_Sing...
I apologize in advance as the question is really a basic and obvious one ... My custom board is using an STM32MP151 SoC.Is it possible to re-write programmed OTP bits (namely, OTP Word 3 for boot modes).My feeling is that, this is not possible (One T...
Hello everyone,I'm currently working with a STM32MP157c. This microcontroller includes multiple timer peripherals (General-purpose timers / Advanced-control timers) and also ADC peripherals. Therefore it is possible to trigger the ADC conversion by a...
I want to know how to use ta to get the startup log information during the bl32 startup phase or if there is another way to store the log information so that I can get it in the bl32 phase
Hi!Could you please give me exact details of following eth PHY error:[ 95.822137] stm32-dwmac 5800a000.ethernet eth0: no phy at addr -1[ 95.826911] stm32-dwmac 5800a000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)Why it searches ad...
Hello,I'm trying to embed an app in the st-linux distribution. I mean that the goal is to have it compiled with bitbake and integrated in a custom st-image-weston.I tried to use the gtk hello world example of Developper section (that run without prob...
HelloI switched to the Distribution package to have access to the layers provided by ST.After I use command repo sync I, a file named layer is created.When I:DISTRO=openstlinux-weston MACHINE=stm32mp1-disco source layers/meta-st/scripts/envsetup.sh I...
