Hi,We are using Stm32mp157a processor in my custom board.We are trying to work on dac with DMA but it is not working.You can see my configurations below.In cube mx for DAC there is no Dma option.so we added DMA manually with reference Stm32mp1 Uart ...
Hello , I am trying to configure RX (only) with dma. I am using DMA2 stream5 on usart3 I have connected USB to UART bridge (4 wire) on 40 pin headers RX,TX,VDD(3) and GND on CN7. Whenever I am trying to send any data from the comport (teraterm ) fro...
I was wondering if its possible to directly flash the STM32MP1 using UART using the STM32CubeProgrammer ? if so are there any tutorials that can be followed ?
I followed the steps to install the mongodb from the openSTLinux distribution.when I run the mongodb from the terminal, it is crashing with the bus error.root@stm32mp1:/usr/bin# mongodBus error (core dumped) Appreciate your help..
Hi, Is there any way to give a more meaningful name to a serial port with the device tree, so that is shows up in the linux kernel?Right now, in a device tree, it is possible to choose an alias in the alias node. But they do show up as ttySTMx in th...
Hi,I was following the instructions from the ST wiki (How to build kernel for Android) on how to build the android kernel, however, on the last step, when instructed to build the final android images (make -j) I get the following error:"Cannot extrac...
Hello, Please tell me how to write DeviceTree to use GPIOF6 ~ 11 and GPIOG10 ~ 15.When I checked the status after u-boot and kernel boot, it became as follows.The ports that can be used when creating and compiling DeviceTree are GPIOF0-5 and GPIOG0-...
I'm not sure if this is a bug, but STM32CubeMX assumes GPIO is input while using LL library? And is not configuring it to be Input ?I found that I had to force to configure the pin as Input so it will work with external interrupts.
Hi All,What is the best way to switch an SPI from Slave to Master during run time and later to bring it back to Slave mode (an example will be well come :-))Thanks,Yoav
We are doing a custom board bring-up and currently trying to display video on our display device. We use CubeMx to generate the device trees for our project, we have configured the DSI PLL dividers to match our display device requirement. Snapshot of...
