Hello, i am using an stm32mp1-dk2 board. For using fw_printenv and other uboot tools from user space one must define a "/etc/fw_env.config" file. I can see that the "/uboot.env" file is driectly saved under the root "/" and so i defined the "fw_env.c...
I am not able to launch SPI activation outputs just using datasheet information. I have tried everything and the status outputs do not change. By making use of an oscilloscope, I have checked that the data bytes transmitted (0xAC01, that would entail...
Hi,we're using STM32MP1 for our project. we have connected super cap to VBAT.our expectation is to have VBAT supply power to RTC *alone*. we dont want RAM content to be retained. so that RTC shall remain powered for long time. currently the VBAT is s...
I have done the yocto build, and i used below bitbake command to generated distribution package.bitbake st-image-weston --runall=deploy_archivesBut i have updated the sources now how to clean and rebuild the archives.used board : STM32MP135FEco syste...
Hello, I have an interprocessor communication problem using the OpenAMP_TTY_echo example on the STM32MP157C-EV1 board.I am tring example OpenAMP_TTY_echo, to comunicate between M4 and A7 on the STM32MP157C-EV1 board.I can't find the solution, and I n...
Hi,my question is how to set up resolv.conf with the DNS nameserver not to lose it after reboot.Some of the manuals on the internet want to modify /etc/systemd/resolved.conf by uncomment DNS line and provide a valid ip. Unfortunately, it's not workin...
Hi all.In my openstlinux yocto image has been included the SGTL5000 audio codec management. I have a problem. On the headphone output I heard only a continuous pink noise.These are some information from my system:zcat /proc/config.gz | grep SGTL CONF...
Hi,My STM32MP157f-DK2 contains the OpenSTLinux image FlashLayout_sdcard_stm32mp157f-dk2-trusted.tsv. The sdcard is 16GB in size. I am unsure whether this is the right OpenSTLinux image to use when i would like to deploy a React / Electron application...
Hi,I am working on a custom hardware based on STM32MP1 mpu and also uses some other peripherals too. For our use case, we are using Yocto Linux. I am using the pin PA12 as an input GPIO interrupt, configured to trigger for falling edge. The interrupt...
Hello everyone.I'm trying to build an embedded openSTLinux Yocto image but I have the following error"ERROR:.. do_rootfs: No manifest generated from: <my_name_folder> in ..."Why does a similar error appears?I explain better. Previously, the build pro...
