RPMSG SDB driver allocates buffers in reserved memory

We have been using RPMSG_SDB driver from LogicAnalyzer example. By default, RPMSG_SDB uses common CMA area for allocating buffers via dma_alloc_coherent() We want to allocate SDB personal buffers from reserved memory regions. We adapted both device...

Can you recommend a Linux MPU development board that has wireless, 1 hdmi input and 1 hdmi output. I want to capture video/audio from 1 hdmi input port and disseminate data wirelessly to other station and hdmi output port?

STM32MP1 trying to add GCC

Hello,I have several python modules I am trying to install that require building something in C. I've read through this and completed a build. I got to the part about adding layers and I'm lost. I've not built a distribution using these tools bef...

Recommendations for web server and platform

I have several devices connected through a CAN network. Using an STM32MP1 I want to build a web frontend that can be used to not only issue commands but also receive arbitrary data and present it to the user. (Data from the devices).I'm trying to f...

ADC in continuous mode only reading once

I am trying to read data using ADC1 continuously and copy it into a buffer via DMA.However, the data is only read and copied once (seemingly correctly), and afterwards nothing happens anymore (data in buffer does not change, ADC1_IRQHandler() is not ...

stm32mp1 i2s1 mclk bitrate issue

Hi in one of link https://wiki.st.com/stm32mpu/wiki/I2S_Linux_driver#Short_Descriptioncan i2s1 used for mclk generation, and will the parent clock able to generate mclk for different audio different bitrate,because in dk2 we use i2s2 for mclk generat...

How to make work (M)DMA pool in SRAM on custom SOM with STM32MP151/7C

We try to configure the (M)DMA in Linux device-tree for our System on Module board based on STM32MP151/7C but it always said us that it cannot configure it so we had to disable dma for memory (QSPI Nor/NAND and FMC Nand) which cause performance issue...
