Hi @WayneWWW
我测试了第2块Orin核心板模组的时候，发现不需要任何hdmi 相关patch，hdmi也可以正常显示和热插拔。第1块Orin Dev Kit和第2块Orin核心板模组 flash log相关Chip 信息如下
第1块：
Chip sku: 0xd0
Board ID(3701) version(500) sku(0000) revision(H.0)
第2块：
Chip sku: 0xd2
Board ID(3701) version(500) sku(0004) revision(G.0)
以下是测试步骤：
step1. full flash，kernel为 0000版。
$ cat /proc/device-tree/compatible
nvidia,p3737-0000+p3701-0000nvidia,tegra234nvidia,tegra23x
step2. 删除 /boot/extlinux/extlinux.conf 中的 FDT /boot/dtb/kernel_tegra234-p3701-0000-p3737-0000.dtb后，reboot，kernel为 0004版。hdmi可正常显示，支持热插拔。
kernel 0004 版dtb，没有apply任何 hdmi相关patch，是jp5.0.2 release纯净版本，有通过 hexdump /proc/device-tree/display@13800000/nvidia,dcb-image 确认。
$ cat /proc/device-tree/compatible
nvidia,p3737-0000+p3701-0004nvidia,tegra234nvidia,tegra23x
另外一个疑问是，烧录到第2块核心板模组分区的是 0004版kernel(dtb)，extlinux.conf使用的却是 0000版kernel，这个是否是bug，该核心板应该使用哪个版本kernel？谢谢！
我发现0004版比 0000版多了以下配置。
