We are having issues getting USB to work as both ethernet and gadget serial.In kernel configuration, We have the CONFIG_USB_ETH configured as inbuilt and CONFIG_USB_G_SERIAL as inbuilt as shown below. ## USB Gadget precomposed configurations#CONFIG_U...
We created the project for the M4 with CubeMX. We use FreeRTOS with CMSIS_V2 and OpenAMP as Middleware.We assigned TIM1, TIM2 and TIM3 to the M4 and use TIM1 as SYS Timebase Source.The program runs fine if started with fw_cortex_m4.sh or with the SW4...
I have the M4 core using a UART core to send and receive data using DMA. This works just fine but over time after 30-60min the core crashes/locks up and reinitializing the UART channel does not help at all it actually crashes the sytem. Under normal ...
I am trying to configure a DMA stream to capture the RX channel of a UART core on the m4, however, I get very undesirable behaviour.I am trying to set up a circular rx buffer that is of size 10 since the data coming back is of multiples of 5. Unfortu...
Hi,We are using stm32mp157c MCU/board and it has DSI output built-in. Now we want to add display port support via DSI to eDP bridge SN65DSI86. It seems that stm32 does not support Displayport output or it has never been done. At least the driver dw_m...
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...
