We need to store some of our application data in BKPSRAM block so we can persist it during power down. Here is the code that we created to write to the BKPSRAM block, could you please help me to define what is wrong. Thanks.#include <sys/mman.h>#incl...
Hello,I'd like to setup a DMA transfer to feed a SPI Display with 8192 bytes per DMA cycle. To offload the MP1 I want to do this with the help of the M4 coprocessor. For my tests I am using the CubeIDE and a custom board. As a basis for learning I tr...
Hi, We have a custom board based on the STM32MP151C CPU and we found that after migration to stm32mpu-ecosystem-v4 (linux-stm32mp 5.15) provided by the meta-st-stm32mp yocto layer (langdale) there are some errors during MMC writing procedure:[ 3358.8...
We designed a STM32MP135 based SOM, without using the ST I2C PMIC, I was able to disable the PMIC driver in TF-A by removing the i2c 4 node in TF-A's dts file, while I could not get the same result for optee-os, even I removed the i2c-4 node in opt...
I am using the FMC peripheral of the STM32MP157 to access the FPGA, the FMC is configured as a Synchronous read synchronous write PSRAM. For the simplicity of the FPGA logic design I would like to have the burst reads and burst writes with CRAM page ...
Dear community,I'm currently having a problem setting up an OPCUA client. Using the open62541 package, I was able to connect to an OPCUA server created in Node-Red. I was able to both read and write to the server's addresses. The connection was made ...
Hi, I have an application where the SPI master is sending data every 2 mSecs. The STM32MP157F-DK2 SPI4 and SPI5 are in slave mode. They are receiving the data as expected but the data is skipped between each transfer on SPI4 and SPI5. The application...
Hi there,I'm new to the Yocto project and have been following this tutorial series in order to familiarise myself with the process. In the series, the presenter is using an STM32MP157 Discovery Kit to walk through the process. I initially followed th...
For a project using the STM32MP135F Discovery kit, I configured ADC1 with an oversampling ratio of 16. However, in sysfs, I can see that the device tree parameter is being ignored: # cat /sys/bus/iio/devices/iio:device0/oversampling_ratio 1 What am I...
Hello Everyone, I am working on a custom board based on STM32MP157F-DK2. Our custom board have two external ADC (AD74413R) connected to the main processor. I have changed the device tree added proper driver for the external ADC. While reading the fi...
