答案对人有帮助，有参考价值 0 If your N9H30 SPI Linux kernel is stuck at a certain point and won't proceed any further, you may want to try a few steps to resolve the issue: 1. Check the hardware connections: Verify that all hardware components are connected correctly, and there are no loose connections or damaged components. Sometimes, a faulty hardware component can cause the system to freeze during boot up. 2. Check the boot configuration: Make sure that the bootloader settings are correct, and the kernel configuration is accurate. Incorrect settings can cause the kernel to fail during the boot process. 3. Check for kernel errors: The kernel may be failing due to some errors or exceptions. Look for any error messages in the console or system logs. Check the kernel messages for any error codes or segmentation faults. 4. Debug the kernel: You can enable kernel debugging options to get more information about the system's state and any kernel-level issues. Debugging options can help you identify the cause of the kernel freeze. 5. Try a different filesystem: If you're using JFFS2, try a different filesystem, such as ext4 or NTFS. Some filesystems may be more stable than others. 6. Try booting from a different device: If using SPI Flash, try booting from a different flash device or using a different interface. It's possible that the flash device or interface might be causing the kernel freeze. 7. Contact support: If none of the above steps resolve the issue, you may want to reach out to the hardware or software vendor's support team for further assistance.
