How can I make these LEDs work on stm32mp157-dk2 board? Ethernet interface is working fine, but both link and activity LEDs are always OFF. I need to have a visual confirmation that Ethernet has some TX/RX activity and thus need these LEDs working. A...
I use the UART4 like the following initialization.void uart4_configuration(void) { GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure; /* enable usart clock */ RCC_APB1PeriphClockCmd(RCC_APB1Periph_UART4, ENAB...
Hi, I loaded Linux start image to DK 2 eval board and it boots ok if it connected to serial terminal on PC (TeraTerm, etc). When terminal is not running or cable is not connected it won't boot.Can I disable that without rebuilding Bootloader/Linux ...
I'm referring to the following website.https://wiki.st.com/stm32mpu/index.php/STM32MP1_Distribution_PackageI stumbled on "6 Building the OpenSTLinux distribution".Error occurred in bitbake.I attach the log.Could you tell me the cause of the error?Bes...
Hi,I'm looking for the simplest way how to gather data from SensorTile board(s) on STM32MP157C-DK2via Bluetooth.Could you please help me to find some examples?Ideally it'd be nice to do it directly on Cortex-A7, e.g. by adapting/making running on S...
Hi,we're thinking about using the STM32MP157 in a product. However, there's still something unclear to us.We need to connect it to a display which only supports the 16-bit Intel 8080 bus (so LTDC cannot be used). I read that it's possible to emulate ...
HI all,I am using an STM32MP15-EV1 eval board and will connect an external amplifier to the HEADSET output. I would like this amplifier to be automatically switched on / off when sound is being played. If I am correct this is supported in the audio-g...
I’m getting a build error when attempting to build the linux kernel.ERROR:scripts/extract-cert.c:21:10: fatal error: openssl/bio.h: No such file or directory #include <openssl/bio.h>I have followed instructions from https://wiki.st.com/stm32mpu/wiki/...
Hi,I need an examples on LCD and USB driver without Linux pleaseThe en.stm32cubemp1_v1-1-0 do not have it, and the STM32CubeMX do not allow this mode.Thanks.Mohammad
Most of the DSI pin mapping is same as ST's DK2 board except DSI_RESET and DSI_TE. I updated the DSI_RESET pin mapping in the device tree to reflect actual connections. However, Weston Wayland compositor fails to start even when DSI display is not co...
