Hi, We would like to drive pin PWR_ON to low for low power mode.First, on MCU, we use HAL library: HAL_PWR_EnterSTANDBYMode(), load to M4 and run it first, so M4 now enter standby mode.Second, on MPU, we set TZEN=0 so non-secure, allow us to modify P...
I am working on a system designed on stm32mp157c mpu. I am trying to setup a remote debugging setup wherein I am running an openocd debugger script on this stm32mp1 mpu. The target I am debugging is an stm32f405 discovery board, which is connected to...
I am working with an STM32MP157d-dk1 board, but am trying to make my own MVP board running yocto on the STM32MP157 chip and have questions concerning the use of the debug console.I believe the debugging console for the dev board runs via uart4, and i...
Hi,I want to configure the LED7 of stm32mp157f-dk2, in arc/arm/boot/dts folder there are stm32mp157f-dk2.dts and stm32mp157f-dk2.dtb file, I cannot edit .dts file since it appears as an audio file and not the text file.so I edited the stm32mp15xx-dxx...
Hi!I am using the stm32mp157C-DK2 board to communicate via FDCAN and my idea is to use it as normal mode to send and receive CAN messages. For this I have created a program in stm32cubeide and I enable FDCAN1 with the following parameters (125Kb/s): ...
Hi,First of all, I am sure I am completely overlooking something, but I can´t seem to figure this out:In CubeIDE I added the FDCAN1 peripheral for my STM32MP157D-DK1 board. I then added the device tree to the build. However, when the board has booted...
I can not find any 8 gigabit memory for the STM32MP157CAA3 What I have found is double the price of the processor! IS46TR16512BL ISSI and Micron ECF840AAACN-C1-Y3I was looking for 256X32 memory but gave up, found some 512X16 but this puts the the cos...
Hello,I am working on a custom board based on STM32MP157A . For USBPHYC i am referring the driver from Linux(V5.13) and some of the registers like STM32_USBPHYC_MONITOR mentioned in the driver file are missing in the reference manual (RM0436).So i j...
Hello to allIs there an example of Interrupt handling in user space?I need to handle external interrupt's in Qt.thanks for your help
Hello,I am working on a custom board based on STM32MP157A and I am getting all the bits correctly but getting values at reserved bits in USBPHYC version register (Internal) which are supposed to be reserved as per the reference manual.Below mentione...
