Resolved! STM32MP157 UART RX suspend wakeup
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...
Cannot enable SPI_STM32 in Kernel using menuconfig (conflicting information in WikiI)
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...
How to get correct ADC values in STM32MP157C-DK2
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...
Resolved! OTP basic question (boot modes - STM32MP151 )
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...
Resolved! Stm32mp1 workshop Virtual Machine archive corrupted
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...
Trigger ADC conversion by Timer in PWM Input Capture Mode in Linux.
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...
Get the startup log information in the bl32 phase.
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
