On the STM32MP157-DK1 schematic there is a note to say "WARNING - do not supply 3V3,5V from Arduino shield", even though it looks as though pin 5 on CN16 is electrically connected to 5V_VIN via a 0R resistor.It's going to be very inconvenient to use ...
The ST33xxxx with backside terminal.My question is about this back side terminal .Which is this terminal conect to GND or Vcc.OR ,Is this used open. thankyou.
I am using an STM32MP151 in linux (5.4.56) and therefore using the DTS to setup some GPIOs i need.I have difficulties setting up PUSH_PULL | PULL_UP configuration in the DTS for my GPIO, while, after linux has booted, using devmem i am successfull in...
I am trying to transmit variables via the uart2 serial port from GY-521(mpu6050) library, however, all my attempts are unsuccessful. typedef init in the main.c:MPU6050_t sensor_data;main.c area to put HAL_UART_Transmit(): while (1) { MPU6050_Read_Al...
hi st expert:I'm updating my yocto version to Ecosystem V4.1.0, but I can not compile suceess in wsl ubuntu20.04, this is error log:log.do_rootfs.23400 as follew:How should this problem be solved? thanks B&RTao
Hi,I am working on the implementation of a AI algorithm in a heat pump. My first choice was the SPEAr320 MPU: it is outdated though, it doesn't have enough resources and any FPU. Which MPU should I choose for this application ? that is to say inferen...
I recently purchased a STM32MP135F-DK Board to develop a IoT application. I'm slowly learning my way though OpenSTLinux. but for a urgent need i need to develop a hand application demo. the product description says it also supports bare metal RTOS ...
Hi, I'm working with the STM32MP157 and I'm trying to interface it with 4 lanes DSI display. the problem is that the STM32MP157 support only DSI with 2 lanes. In the other hand, I can't program the controller of the display (JD9365DA-H3) to switch wi...
Hello,I want to send in reliable way messages from M4 core to A7 core (in my case its the HW is STM32MP157 -DK2 ). The problem is that when A7 core is busy, the messages are truncated.The quesiton is how M4 core would know that A7's buffers are full?...
Hello,I want to upgrade my hardware to new openstlinux kirkstone release november 2022.First test on eval board was successful.I have written custom device tree files and compiling for tf-a, u-boot, fip and kernel is fine.However when I try to flash ...
