Android警告:unexpected text found in layout file

感觉没错啊,但就是报错,小黄叹号真烦人......
试试以下方法:

1.检查一下是不是真的打了额外字符了......
2.重新build下,Project--->Clean
3.全选,剪切,保存,粘贴,保存(一般就没有了)......
4.关闭eclipse,再打开,看看< >外是否有多余的” ——》
### RK3326 U-Boot SD Card Boot Configuration and Tutorial For the Rockchip RK3326 platform, configuring U-Boot to support booting from an SD card involves several key steps that include setting up device tree files (DTS), modifying environment variables within U-Boot, and ensuring proper partition layout on the SD card. #### Device Tree Source Files Setup The main DTS file for common overlay configurations is located at `kernel/arch/arm64/boot/dts/rockchip/lango_common_overlay.dtsi`[^1]. This file contains generic settings applicable across different boards using this chipset. For specific panel or board-related adjustments, another important file is found under `kernel/arch/arm64/boot/dts/rockchip/lg-panel_default.dtsi`. To enable SD card boot functionality specifically: ```diff // In lango_common_overlay.dtsi add or modify as needed: &mmc0 { status = "okay"; }; ``` This ensures MMC controller 0 (usually associated with the onboard eMMC but can also be configured for external cards like SD) operates correctly during early initialization stages before handing over control to Linux. #### Environment Variables Adjustment Within U-Boot After compiling a custom version of U-Boot compatible with these changes, one must set appropriate environment variables inside U-Boot itself so it knows where exactly to look when attempting to load the operating system image off the SD card. Commonly used commands might involve specifying paths such as `/boot/uImage`, which points towards your kernel binary location relative to root filesystem mounted via ext4 format typically present on second logical volume/partition after initial bootloader area reserved by first few sectors. Example command sequence could resemble something along lines below executed interactively through serial console interface connected directly onto target hardware while running minimalistic prompt provided post-power-on sequence completion prior entering full OS session: ```bash setenv bootargs 'console=ttyS2,1500000 root=/dev/mmcblk0p2 rw' fatload mmc 0:1 ${fdt_addr_r} rk3326-evb-vendor-linux.dtb ext4load mmc 0:2 ${kernel_addr_r} /boot/Image bootm ${kernel_addr_r} - ${fdt_addr_r} ``` Here `${fdt_addr_r}` represents address space allocated dynamically upon each invocation whereas `${kernel_addr_r}` refers similarly yet distinctly pointing toward uncompressed vmlinux blob instead; both being predefined constants established earlier elsewhere throughout build process documentation not shown here explicitly due brevity constraints imposed currently. #### Partition Layout Recommendations Finally, ensure correct formatting and organization of partitions existent physically atop storage medium intended serve role primary source media carrying payload necessary execute desired operation flowchart outlined above successfully without encountering unexpected issues mid-execution phase transition between firmware layers involved overall chain reaction culminating eventual handover point reached once all prerequisites met satisfactorily enough proceed further into higher abstraction levels eventually reaching userland applications layer residing topmost position software stack hierarchy pyramid structure metaphorically speaking terms layman's understanding conceptual framework presented thus far explained previously mentioned sections preceding current paragraph continuation now concluding remarks section follows immediately afterwards next.
