Hello,
It seems you’re encountering an issue where your device tree overlays are reported as applied, but the expected changes are not visible on your board. Let’s go through some steps to troubleshoot and ensure your overlays are correctly applied.
-
Verify Overlay Content: Ensure that your overlay file (
colibri-imx7_LE_overlay_test.dts) correctly defines the changes you expect, such as the addition of thetextvariable. Double-check the syntax and structure of your DTS file. -
Compile the Overlay: Make sure the overlay is compiled into a
.dtbofile correctly. You can use thedtc(Device Tree Compiler) to manually compile your DTS file to verify it compiles without errors. -
Check Overlay Application: Use the
torizoncore-builder dto statuscommand to confirm that your overlay is listed as applied. If it shows a value of0, it indicates the overlay is applied successfully. -
Inspect the Device Tree: After confirming the overlay is applied, inspect the device tree at runtime. You can use
ls /proc/device-tree/to navigate andcatto view specific nodes and properties. Ensure yourtextvariable is correctly placed in the expected node. -
Reboot the Device: Sometimes, changes might not reflect until the device is rebooted. Ensure you reboot the device after applying the overlays.
-
Review Logs: Check the system logs (
dmesg) for any messages related to device tree application. This can provide clues if something went wrong during the boot process.
If after these steps the issue persists, consider revisiting the overlay’s logic and ensure it aligns with the hardware configuration and requirements. It’s also beneficial to compare with a working example or reference overlay to identify any discrepancies.
I hope this helps resolve your issue.
