…ction Fixes radxa-docs#1782 - Add pre-flight check: ls /dev/fastrpc* before running test - Add troubleshooting steps when device nodes are missing: - lsmod check for fastrpc kernel driver - modprobe qcom_fastrpc to load driver manually - Remind users to use official RadxaOS image (driver pre-installed) Triggered by GitHub issue radxa-docs#1782: Dragon Q6A + Ubuntu 24.04 user installed fastrpc packages but /dev/fastrpc* did not exist because the kernel driver was not loaded. The docs previously jumped straight to fastrpc_test without verifying device node presence.
