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...
Hi all, I am trying to flash a custom board based on stm32mp157c based MPU. I have my own flashlayout which is also attached here. I am constantly running into the following error. an error occured while setting virtual partition 0xF1 alternate...
Hi,I am puzzled which DMA channel to use to read from an FPGA connected to the FMC.Using the dmatest module I found out which are free and can be used for DMA_MEMCPYtransfers:modprobe dmatest timeout=2000 iterations=1 run=1 wait=1 [ 991.821537] dma...
Hi all,I am trying perform build for yocto for the DK2. But running into the following error. I am pretty sure this was working until a month back but now link appears to be broken. ERROR: openocd-stm32mp-native-0.11.0-rc2.AUTOINC+a5e526d857-r0 do_fe...
Hello,I been working on stm32mp1 soc. In m4, totally, i have configured 3 timers(Timer2(input capture), time13,timer16). when i start the m4 from A7 after Linux login, all timers work fine. But when I use a startup script to start the M4 during Lin...
