Hello,We are considering the STM32MP151x MPU for a new project. However we need at least 20 independent PWM outputs (at the same frequency but different duty cycle). After reading the datasheet, it is still not clear to me how many PWMs STM32MP151x h...
smt32mp157a-dk1/c-ev1 boards. When BOOTSCHEME_LABELS (stm32mp1-eval.conf) is changed from "trusted" to "basic" the build of u-boot-stm32mp recipe fails. Ecosystem 1.2.0 .
Hi everyone, i am trying to run Distribution package from the STM on UBUNTU. It works fine with normal source command and make a build directory just by the folder of 'layers'. but how can i add my own build directory e.g. /mybuild/build_folder? I h...
Hi,I execute the following commands according to the wiki:(I am sure accept the EULA)PC $> DISTRO=openstlinux-eglfs MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.shPC $> bitbake st-example-image-qtThe following is part of the terminal outpu...
The program can not be uploaded under the dunfell distribution via CUBEIDE 1.3.1 to the target system. Using the thud distribution, target uploads works.Are there any hidden upload scripts in the CUBEIDE - how to debug the debug upload?Which yocto pa...
Hi allI want to implement dual display using STM32MP157C chip and OpenSTLinux system.Is it possible to implement dual display using MIPI DSI / LTDC / HDMI-CEC?If you know the answer above, please reply.RegardsMachilus
I am testing Ethernet on the STM32MP1 (on both the EV1 and DK2 eval boards) and seeing slow link up times when the board is connected to a Gigabit Ethernet switch. Here's an excerpt from the dmesg traces showing link up times of 6-7 seconds:[ 8.93...
Apparently it is not possible to set a custom baud rates for UARTs on the STM32MP1.ioctl TIOCSSERIAL fails. With a USB UART dongle that supports custom baud rates this works. Is there a something that can be changed in the device tree or config to en...
Hello,I am currently initializing my STM32MP157CAC3 (TFBGA361) with CubeMX.The processor's datasheet lists USB_OTG_FS functionality as additional functions on PA11 / PA12 but there is no such selection inside CubeMX. In general, there is no USB_OTG_...
Hi,we were facing trouble booting the Ecosystem 2.0 with the new U-Boot (v2020.01-stm32mp-r1). We are using buildroot as the tool to build our distribution. With the Ecosystem 1.2 we could build everything perfectly and the booting was fine too. We u...
