最新git sdk
我在自己添加节点，实现rk355 控制rk628d，也看了你们论坛其他相关文档。麻烦请支持下；
从今年的2月份就有人发论坛后，说后续会支持rk628d，现在时12月中旬了，我刚前二天发帖还是说后续会支持.....
我现在就自己调试一个hdmiin 转mipi就可以了。
报错如下
rk3566_firefly_aiojd4:/ $ dmesg |grep 'rk628'
[ 1.020168] rk628 2-0050: failed to access register: -6
rk3566_firefly_aiojd4:/ $ dmesg |grep 'rk628'

dts配置如下： 我用的是i2c2,从模式&i2c2 {
