I'm just confused since other kits (ex: STM32H750B-DK) have provisions for jumping the 2 lines together, but the wiki does not indicate the BK2_NCS GPIO (from the MPU) is even used by the BootROM. I wanted clarification of the statement made on the ...
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 ...
