Hello! Our company recently conducted kernel compilation tests on the Apalis Evaluation Board Rev 1.1 based on the guidance in your developer centre document “Build Linux Kernel from Source Code | Toradex Developer Center”. We would like to consult with you regarding the technical phenomena encountered and kindly request your guidance.
- Operating procedure:
● Compile the Linux kernel from the BSP 7.1.0+build3 version source code
● Replace the Image.gz file in the original BSP package
● Deploy to the development board using the Toradex Easy Installer tool. - Abnormal Phenomena:
● No video output after system startup (HDMI interface)
● USB peripherals not recognised (keyboard, USB drive, etc.)
● Serial terminal can connect normally and execute command line operations. - Comparison Validation:
● Video output and USB functions are normal when deploying with the original BSP image
● Hardware connections and power supply conditions remain completely consistent…
Please confirm:
- Does the phenomenon described above align with the expected behaviour after kernel replacement?
- If it is an abnormal phenomenon, what are the possible compilation/deployment steps that may need correction?
- Are there any driver module compilation configuration items that require special attention?
