meta-st-stm32mpu-app-logicanalyser

This layer is used to bring the logic analyzer demonstration (see details in https://wiki.st.com/stm32mpu/wiki/How_to_exchange_large_data_buffers_with_the_coprocessor_-_example) on top of STM32MP1 MMDV-3.0.0.

This layer is linked with the https://github.com/STMicroelectronics/logicanalyser project (STM32MP157 Cortex-M4 firmware for the logic analyzer demonstration).

This demonstration is planned to be executed on the STM32MP15 Discovery Kits boards.

The "mx machine" is not used anymore: instead, a patch on the Linux device tree is provided.

1. How to add the meta-st-stm32mpu-app-logicanalyser layer to your build ?

Get the meta-st-stm32mpu-app-demos-cam layer:

PC $> cd <root of the baseline>/layers/meta-st/
PC $> git clone https://github.com/STMicroelectronics/meta-st-stm32mpu-app-logicanalyser.git -b dunfell

Configure your machine, your distro, and source your environment:

DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh

Add the meta-st-stm32mpu-app-logicanalyser layer to your environment:

PC $> cd <root of the baseline/build-openstlinuxweston-stm32mp1
PC $> bitbake-layers add-layer ../layers/meta-st/meta-st-stm32mpu-app-logicanalyser

Then, you can build the baseline and flash the built image as usual.

2. How to run the demonstration?

1. Press the "USER1" button to start (resp. stop) the demonstration
2. Select the sampling frequency (4 MHz per default)
3. Start the sampling: the samples compressed data are stored in a ".dat" file in the "/usr/local/demo/la" directory
