Hi, we using the STM32MP157 custom board in this we are developing the bare metal drivers for the all the peripherals. Now we are able to send and receive the character on UART4 perfectly. But when we are configuring for the interrupt mode it's o...
Hi,I am using STM32MP153a SOC.Linux kernel version is 5.4.56 (openstlinux-5.4-dunfell-mp1-20-11-12).I would like to generate square signal of 50-200 uS on a certain GPIO every 40 ms using Linux kernel.Also ,at this point I need to read certain regist...
I noticed that some ST Cpus support large amounts of RAM. Does this mean that they would run Linux, too. Are there any demo boards and such. Our volumes are 100-400 per year, if we ever start building our own Linux boards.
I cannot make the Ethernet work on my custom board (STM32MP153CA + automotive Ethernet PHY NXP TJA1101) in U-BOOT (haven't even tried loading kernel). The PHY is connected to an external 25MHz xtal. I'm working with 5-10-dunfell-mp1-21-11-17 files in...
Hi, and yet another question...We would like to perform electrical compliance testing on our USB ports. This requires each port to send a test pattern.Our board has one upstream and two downstream facing ports. The upstream port can be set into vario...
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...
