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...

Hi,We are using stm32mp157a in our custom board.We are configured SAI for Cortex M in cubemx.But we are unable to get dma interrupt and data through DMA. you can see my code flow below.In main.we are calling below functions.int main(){ MX_DMA_Ini...
Hello Attached is my i2c ioc file and I have connected an ADXL sensor to the stm32mp1 on its Arduino connector(I2C5). ( address: 3A, Chip id value : E5, Chip ID read register : 0x00)I am trying to read this chip id but getting an error at the below...
Hi STI enabled DISTRO_FEATURES_append = "tpm2" in the file ".../layers/meta-st/meta-st-openstlinux/conf/distro/include/openstlinux.inc" as described in the ST Wiki.When building with "st-image-weston" I get the following error message:ERROR: Nothing ...
Hello, I have two questions : (1) Is I2C5 the one on which the peripheral can be connected on the I2C lines on the Arduino connector with the cortex M4? I checked this and it is I2C5.PLease correct me? (2) I was trying to search/look the BSP methods ...
