使能HDMI后，系统会出现一个异常告警
-
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，

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

芒果的tina linux的HDMI驱动有问题，更新了驱动但是接口没更新，现在先回滚到老版本驱动
-
@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！

@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
