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 ...
I'm having trouble resetting the board from linux.Not using a PMIC but discrete power supplies.I followed the app notes and errata, connecting the NRST and CORE_NRST pins with a cap then later a 0R resistor.I'm using a single 100nF cap on NRST.I can ...
Hi All,i have my own board based on STM32MP157C.I connected usart1 (tx, rx, cts, rts) to Wifi/Ble module and i still got the same error:stm32-usart: probe of 5c000000.serial failed with error -22I discovered that USART1 is a secure device so i need t...
Hi, I'm MesutI'm working STM32MP157C and use DP83867IRRGZ Ethernet Phy in RGMII Mode. There is no 125 MHz from CLK_OUT of DP83867IRRGZ on default mode.But STM32MP157C need 125 MHz on its PG5 pin. For STM32MP157C we must provide a 125 MHz clock from ...
