random things I made and things I learnt making them
The STM32CubeIDE can be used to generate device tree source file (.dts) for your embedded linux image. These describe the hardware for the board on which linux will run. This is compiled into a device tree binary file (.dtb) which is included on the image and loaded by u-boot along with the Linux kernel zImage.…
Custom Board Design First lets discuss the hardware. There are vendor boards available: Evaluation boards are expensive due to the large number of external connectors and integrated circuitry (including FPGAs and HDMI decoders!). These are really meant for sales demos. Any development work done on these would be wasted time since your own custom design…
So you have the discovery kit and you have run the example image on the SD card. But how do you build an OpenSTLinux image from scratch with Yocto, using a device tree file file generated by STM32CubeIDE? We will go through the build chain setup, the device tree configuration and the build process. There…
