@whycanservice 谢谢的答复，我用https://github.com/Tina-Linux/linux-5.4
替换原来内核，测试了一下，原来的异常告警消除了

@whycanservice 谢谢答复，我试一下

我重新找了一台默认是1920x1080分辨率的显示器，上电可以显示小企鹅logo， 提示中依旧存在以下告警，

[ 2.955732] HDMI cable is connected ... [ 4.871018] [HDMI2 error]: sink do not support this mode:16 hdmi_sink中有屏的信息了,但是不是1080P /sys/devices/virtual/hdmi/hdmi/attr//hdmi_sink Video Mode: 720P60 Only Support YUV420: Also Support YUV420: Pixel Format: RGB YUV444 YUV422 Deep Color: RGB444_30bit YUV444_30bit RGB444_36bit YUV444_36bit Basic Audio Support: YES Audio Code: LPCM HDCP Tpye:

用 dd填充framebuffer, 可以看到显示有变化
dd if=/dev/random of=/dev/fb0

这里的模式告警不知道是哪个参数不匹配？

[HDMI2 error]: sink do not support this mode:16

相同板子，处理器是D1s, 继续测试RTL8189FS，却很稳定，没有出现问题

D1s上spi操作有同样的问题，而且spi驱动里的函数执行卡死后，没有任何结束进程的方式。不知道全志解决这个spi驱动的问题了没有

上面的描述有一个错误， 不是sdc2，wifi接在sdc1上面

@yteraa
明白了，谢谢你

@gonboy 在 XR829无线模块购买途径？ 中说：

@xiaowenge 是否方便提供下购买方式？

由于无法重建boot0_sdcard.fex， 参见下面对fex文件的分析，直接修改二进制文件boot0_sdcard.fex

https://whycan.com/t_6638.html
https://linux-sunxi.org/Boot0

调整为UART3以及PB6, PB7的管脚复用定义，然后重新生成文件的checksum

boot0_sdcard.png
然后重新烧录，最终效果boot0和opensbi在UART0和UART3都无输出显示

uboot和kernel的显示成功转到UART3上

不知道为什么boot0和opensbi的串口输出没有起效果，哪位大佬能指点一下？ 谢谢
