问题描述

我参考 https://www.kendryte.com/answer/questions/10010000000006970
下载了工具链、K230 Linux SDK 和小智代码，修改了板级配置：

BR2_PACKAGE_WEBSOCKETPP=y
BR2_PACKAGE_BOOST=y
BR2_PACKAGE_BOOST_JSON=y
BR2_PACKAGE_BOOST_LOG=y
BR2_PACKAGE_BOOST_SERIALIZATION=y
BR2_PACKAGE_BOOST_URL=y

make CONF=k230_evb_defconfig 编译 K230 EVB 固件

luckfox@luckfox-virtual-machine:~/canmv_k230_linux/k230_linux_sdk/output/k230_evb_defconfig/images$ ls
boot                                         k230-evb.dtb
boot.ext4                                    rootfs.ext2
deb                                          rootfs.ext4
EVB-K230_linux_v0.6.4_nncase_v2.10.0.img.gz  rootfs.tar
fw_jump.bin                                  sysimage-sdcard.img
fw_jump.elf                                  sysimage-sdcard.img.gz
fw_payload.bin                               uboot
fw_payload.elf                               u-boot.bin

我尝试烧录 EVB-K230_linux_v0.6.4_nncase_v2.10.0.img.gz 和 sysimage-sdcard.img，都报错：
boot failed with exit code 8

请修改拨码开关，把启动方式修改为从tf卡启动。

boot failed with exit code 8 ---错误原因是 nand 擦写错误，请修改下启动管脚拨码开关。

谢谢，已经从SD成功启动了。
但是屏幕似乎有些问题：

我没有修改设备树文件，这是为什么？

Octopus3

ls -lh /boot
#目前v3镜像默认显示使用的是lcd，如果想切换成hdmi，请修改/boot/k.dtb文件 ln -s xxxxx k.dtb

k.dtb -> k230-evb.dtb 没有修改就是这样

Octopus•

evb 的镜像 目前只支持lcd，不支持切换，我刚才弄错了。

wjx•

执行下 vglite_cube 或者 vglite_drm 命令 看下屏幕显示是否正常

wjx1251

对，肯定需要修改设备树，纯linux这个仓库目前对evb支持不好，evb就没有怎么卖，我有空也测试下。evb的显示和sensor大概率是有问题的。

不正常

我看设备树里面 屏幕是 display-hx8399-1080x1920.dtsi ，你目前用的是这个屏幕吗？
