Hello all,I'm working on a custom board based on a stm32mp157c & stpmic1 (connected on I2C4). We are using secure boot and have configured the I2C4 to work in secured mode. To control the stpmic1 from the unsecure / normal world, we use the scmi-reg...
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...
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...
