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,I am using an stm32mp157c-dk2 and browsed the stm32mp1 workshop MOOC : https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/STM32MP1_workshop.htmlI tried launching the pre-configured VM given here : https://drive.go...
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
Hello,we are bringing-up our custom STM32MP157AAB3 board and we are facing some errors in linux with the uSD that it's connected to the SDMMC1 interface.Here follows our setup:HWSDMMC1 cabled to a uSD connector, PE9 used as card detectSDMMC2 cabled ...
Hi!During loading flash_layout image to custom STM32MP1 I've got following error after staring u-boot and truing to load information to partition 0x04 fsbl1:U-Boot 2020.01-stm32mp-r1 (Jan 06 2020 - 20:56:31 +0000)CPU: STM32MP157DAB Rev.ZModel: STMicr...
