| Title: Send Tracing Formatted Packet To The Host With Supported Backends |
| |
| Description: |
| |
| This application can be used to demonstrate the tracing feature. The tracing |
| formatted packet will be sent to the host with the currently supported tracing |
| backend under tracing generic infrastructure. |
| |

| |
| Usage for UART Tracing Backend: |
| |
| Build a UART-tracing image with: |
| |
| cmake -DBOARD=mps2_an521 -DCONF_FILE=prj_uart.conf .. |
| |
| or: |
| |
| cmake -DBOARD=mps2_an521 -DCONF_FILE=prj_uart_ctf.conf .. |
| |
| NOTE: You may need to set 'zephyr,tracing-uart' property under the chosen |
| node in your devicetree. See boards/mps2_an521.overlay for an example. |
| |
| After the application has run for a while, check the trace output file. |
| |

| |
| Usage for USB Tracing Backend |
| |
| Build a USB-tracing image with: |
| |
| cmake -DBOARD=sam_e70_xplained -DCONF_FILE=prj_usb.conf .. |
| |
| or: |
| |
| cmake -DBOARD=sam_e70_xplained -DCONF_FILE=prj_usb_ctf.conf .. |
| |
| After the serial console has stable output like this: |
| |
| threadA: Hello World! |
| threadB: Hello World! |
| threadA: Hello World! |
| threadB: Hello World! |
| |
| connect the board's USB port to the host device and |
| run the trace_capture_usb.py script on the host: |
| |
| sudo python3 trace_capture_usb.py -v 0x2FE9 -p 0x100 -o channel0_0 |
| |
| The VID and PID of USB device can be configured, just adjusting it accordingly. |
| |

| |
| Usage for POSIX Tracing Backend |
| |
| Build a POSIX-tracing image with: |
| |
| cmake -DBOARD=native_posix -DCONF_FILE=prj_native_posix.conf .. |
| |
| or: |
| |
| cmake -DBOARD=native_posix -DCONF_FILE=prj_native_posix_ctf.conf .. |
| |
| After the application has run for a while, check the trace output file. |
