Hi, I'm trying to build a Yocto-Linux for an specific STM32MP157 board. I was working with "thud", but now "dunfell" is required, as it is supposed to be long term stable.The system is built after ST's manual:https://wiki.st.com/stm32mpu/wiki/How_to_...
I want to know how to specify the address to load Cortex-M4 firmware when U-Boot or Linux Kernel load the firmware of Cortex-M4 in Retention RAM.And, how to specify the address to load Cortex-M4 firmware if I load the firmware of Cortex-M4 in Retent...
want to exchange large data buffers with the coprocessor.I have done following wiki page.https://wiki.st.com/stm32mpu-ecosystem-v1/wiki/How_to_exchange_large_data_buffers_with_the_coprocessor_-_example#Source_codeI want to analyze Cortex-M4 source ...
Trying to run some test code on the M4 core of a custom stm32mp151a board and can't seem to get far. I have been successful in getting u-boot working on the A core, so the majority of the board has been proven functional.I will attach my make file as...
I'm looking for CAD symbols and footprint for STM32MP15x in LFBGA-354 package. Could you guys help me on this? Thank you.
I want to implement the program that exchange large data with each other on Cortex-A7 and Cortex-M4 by using DDR.Thanks to following wiki page, I have understand the mechanism that exchange large data from Cortex-M4 to Cortex-A7 by using DDR.https...
Hi,Can I access APB5 bus in engineering mode to run I2C4 with I2C4_SCL = PZ4, I2C4_SCL = PZ5?
Following the instructions found in en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24.tar.xz and using create_sdcard_from_flashlayout.sh to write the data to an SD card did not work for me. When I inserted the card on the stm32mp157c-dk2 dev bo...
Is there a way to directly start M4 and run M4 firmware from BootRom.I am aware of the Engineering mode, however it requires the help of a debugger to copy the M4 firmware into the memory and run it. I like to do the same but in stand alone mode.I am...
I am evaluating some embedded software libraries which are available for multiple ARM Cortex M3/M4 MCUs from ST. I would like to evaluate what would be the porting effort to port these libraries to the embedded M4 core in the STM32MP1.What is the clo...
