RAM Console Snippet (ram-console)
west build -S ram-console [...]
Overview
This snippet redirects console output to a RAM buffer. The RAM console buffer is a global array located in RAM region by default, whose address is unknown before building. The RAM console driver also supports using a dedicated section for the RAM console buffer with prefined address.
How to enable RAM console buffer section
Add board dts overlay to this snippet to add property zephyr,ram-console
in the chosen node and memory-region node with compatible string
zephyr,memory-region as the following:
/ {
chosen {
zephyr,ram-console = &snippet_ram_console;
};
snippet_ram_console: memory@93d00000 {
compatible = "zephyr,memory-region";
reg = <0x93d00000 DT_SIZE_K(4)>;
zephyr,memory-region = "RAM_CONSOLE";
};
};
