重复几十次测试，没有卡住， 我就要下面命令加大收发数据量，也不会卡住

spi-pipe --device=/dev/spidev0.0 -b 8 -n 256 -s 1000000 < /dev/zero

然后我再把调试关闭，重复几次，很快就复现原来的问题

卡住了，后面没有输出了

我用示波器观察，最后一次卡住时，也是有波形的，感觉spi的驱动没有收到传输结束中断，调试输出可能会影响到中断的设置时序，请大侠帮助分析分析，谢谢！

在T113/D1s上都可以重现，我对比了一下它们驱动sunxi_spi.c是相同的

T113的软件版本

硬件平台mq-pro, 软件tina-linux
1） 一台支持HDMI显示器
2）一块HDMI液晶屏，支持800x480分辨率下面是它的连接
https://item.taobao.com/item.htm?spm=a1z09.2.0.0.77dd2e8dU1iETV&id=646568908641&_u=21njr0q8040

软件上电默认是模式2 (720x480P)，在HDMI显示器可以看到小企鹅，填充/dev/fb0内容可以看到变化

但是接到HDMI液晶屏上，屏可以点亮，但是只是呈现一片白色，填充/dev/fb0无变化
可能是参数的问题，分别读出EDID和解码如下：

@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 谢谢你的答复，我还是有点不清楚

芒果tina-linux是 https://github.com/mangopi-sbc/Tina-Linux

它的内核的linux-5.4 https://github.com/mangopi-sbc/tina-linux-5.4

我看它的提交记录 https://github.com/mangopi-sbc/tina-linux-5.4/commits/0d4903ebd9d2194ad914686d5b0fc1ddacf11a9d
只有7次提交，没有HDMI驱动的修改提交，不知道应该如何回滚到旧的版本？

但是我也没有找到官方tina-linux-5.4的链接，这样就可以把整个内核替换掉， 我看到由YuzukiTsuru维护的一个版本 https://github.com/Tina-Linux/linux-5.4， 不知道是否可用？或者能否提供一个链接，谢谢！

下面是修改后的dts和kernel的配置文件， 哪位大侠能够指点一下？

uboot-board.dts
kernel config
board.dts

硬件平台mq-pro，软件是tina-linux
https://github.com/mangopi-sbc/Tina-Linux

按D1哪吒HDMI测试固件20210804中的描述修改bootlogo.bmp, uboot-board.dts 和board.dts和kernel config, 下是修改后文件

如果系统起来后，会有一个异常告警，

是HDMI模块， 系统还能够正常运行下去，不能再检测HDMI线的插拔过程了。/dev/fb0也是可以正常工作的，填充/dev/random数据可以看到显示的变化。

如果先不插HDMI线，等系统起来后，再插入HDMI，会有同样的异常。下面是完整启动记录

@whycanservice 谢谢答复，我试一下

硬件mq-pro, 软件是官方tina-linux
https://mangopi.org/_media/undefined/tina-d1h-mq-pro-overlay-hdmi-wifi.zip

uboot起来后直接就引导系统，似乎bootdelay设为0了

Warning: eth0 (eth0) using random MAC address - fe:91:c9:dd:14:f7
Hit any key to stop autoboot:  0
dsp0:gpio init config fail

进入系统后

root@TinaLinux:/# fw_printenv
Warning: Bad CRC, using default environment
Error: Please reboot, uboot will fix the environment

无法读取uboot环境变量，

直接dump /dev/by-name/env

中间含有字符串bootdelay=0， 如果不重新编译uboot
如何调整bootdelay，使得能够进入uboot界面，哪位大侠能指点一下？谢谢了

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

@whycanservice 谢谢，我再试试其他显示屏

@whycanservice 谢谢答复，我依次试了列表中一下各种模式， 都会报下面错误

[ 284.524399] [HDMI2 error]: sink do not support this mode:20

后面模式号20，会根据设置的不同参数变化

我有一点疑问，比如默认HDMI的模式1080p60， 如果他读取到屏的参数（支持的各种分辨率800x480, 640x480...）

1. 它是会根据屏的参数调整自己模式， 自己模式是动态的，
2. 还是自己模式是静态配置的，仅仅检查自己的模式是否在屏支持列表中， 如果不在就报错
