Of the many things I have been struggling withmSTM32MP157F-DK2 throughout this summer, one of them is the interprocessor communication between A7 and M4. I want A7 to process data and send the refined result to M4 for further low level actions. As ma...
Hi,I want to generate Interrupts from Core0(First A7) to Core1(Second A7)in stm32mp157A at Uboot Level .We are using St distribution Uboot source Code.Can Anyone Tell the Procedure for Generation of Interrupts .
Hello , Is the BlueZ supported or added in the Distribution or developer or starter image?I tried running bluetoothd -v to get the version of the bluetoothd (and hence the Bluez which has this demon built) but I got this :root@stm32mp1:~# bluetoothd ...
I designed my robot control system using STM32MP157f-K2 board I use the M4 core to read an IMU through SPI, read encoders and generate PWM for controlling the motors by using timers. I use A7 to read USB vision cameras, read a radar by using CAN bus,...
Hi all,I am trying to achieve DDR data transfer between M4 and A7.So I followed How to exchange data buffers with the coprocessor - stm32mpu article and built a yocto image. I have stripped down the logic analyzer application : here . On CM4 side it ...
Hello Team,We are using a product build around STM32MP157C. We have a requirement for programming the OTP with MAC Id. Here is my understanding on the same:The OTP_57 and OTP_58 are meant for MAC addressMAC address can be programmed from the uboot us...
Hi,I have a STM32MP157a-dk1 discovery board and a SX 1280 – Semtech (E28 2G4M27S - E-Byte) module. With CubeMX I add SPI5 to the architecture and get the outputs (Kernel, TF-A and U-boot files.) Then by using these output files I can generate the DTB...
I am using OSD32MP1 (based on STM32MP157c) in Production Mode with OpenSTLinux on Core A7 and FreeRTOS on M4. One of the tasks is to timestamp ADC data acquired by M4 at very highspeed, very precisely (think it order of nanosecond to microsecond). No...
i have read the article, https://wiki.st.com/stm32mpu/wiki/How_to_start_the_coprocessor_from_the_bootloader#Starting_the_coprocessor_firmwarewhere will i find this in my device tree#define CONFIG_EXTRA_ENV_SETTINGS \ "stdin=serial\0" \ "stdout=serial...
Hello guys.I have configured ethernet on STM32MP157F using Microchip's LAN8720AI-CP.I base my image on st-image-core of Distribution Package. And dts is configured using CubeMX(meta-st-stm32mp-addons).Currently, it appears as if ethernet is connected...
