Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
On the STM32MP1, when booting from serial NOR flash, the STM32 MPU Wiki states "In dual mode, BK1_NCS shall be connected to BK2_NCS on board." Should MPU BK1_NCS and BK2_NCS GPIOs actually be connected, or rather is BK2_NCS GPIO unused? I'm just conf...
Hi, i'm using Yocto to build a custom openstlinux image for a stm32mp157d-dk1, but i would like to upload the image using the mass storage mode, enabled with u-boot, or something like that.
My device tree is the following:&sdmmc1 { pinctrl-names = "default", "opendrain", "sleep"; pinctrl-0 = <&sdmmc1_b4_pins_a>; pinctrl-1 = <&sdmmc1_b4_od_pins_a>; pinctrl-2 = <&sdmmc1_b4_sleep_pins_a>; cd-gpios = <&gpiog 1 (GPIO_ACTIVE_LOW | GPIO_P...
Good afternoon, I wrote a program for controlling the railway scoreboard in Python 3 for the STM32MP157A-DK1 board. I have a problem. It is described by the link https://bugs.launchpad.net/ubuntu /+source/gnome-control-center/+bug/1264368Troubleshoot...
Hi All,i'm having an issue with STM32MP157c and audio driver WM8994 (same as used into STM32MP15-DK).At boot time i'm still have the following error:[ 4.250237] ALSA device list:[ 4.251761] No soundcards found.I share the electrical drawing of o...
Hello experts,I am in purpose of developing driver of the peripheral CRYP1 with MDMA on STM32MP157C-DK2 board.I refer to STM32MP157 advanced Arm®-based 32-bit MPUs - Reference manual(RM0436),firstly in page 1160, CRYP1 is AHB5 source, and two stream ...
EDIT: Found the solution, read for implementationI'm trying to get the MPU to exit from standby. PWR_ON goes to 0 as expected on shutdown, so far so good.I'm using PA2 (WKUP2) but it's not working at all...Is there anything special to setup in the de...
Hi there, I am writing an application that requires large streams of IPCC. At the moment I have allocated the RPMSG vdev0 and vrings to SRAM3+4 and I have increased the buffer size of each ring to 1024. The device tree now looks like this: vdev0vring...
Hi, In the Distribution Package, I have created a new machine inside my own layer. I'm running the environment script like this: MACHINE=stm32mp1-my_machine DISTRO=openstlinux-eglfs source layers/meta-st/scripts/envsetup.shHowever, it's not possible ...
