请求适配 hd9901 (rk3399)

[dtamade]

这个板子跟 smart am40 类似,但是我刷了仓库里 am40的固件 会出现硬盘的只读问题.
经过反编译 dtb 发现dts有点出入,请求兼容适配,现将 这个 hd9901能用的固件的 dts 发上来.谢谢大牛.

rockchip-hd9901.zip
重新上传了 包含原固件的dtb文件一起

[sjllls]

compatible = "bozz,sw799a\0rockchip,rk3399";
上传的并非HD9901原始固件中的dts，难以作为参考

[dtamade]

compatible = "bozz,sw799a\0rockchip,rk3399"; 上传的并非HD9901原始固件中的dts，难以作为参考

我看了一遍大概跟电源和mmc的定义差异有点关系.
正在熟悉 dts规范中,想尝试修复

EMMC随机正常工作，没出现坏块，基本上就是供电不足。
HD9901的EMMC是KLMAG1JETD-B041，电压是1.8 / 3.3 V
AM40的EMMC电压是闪迪，具体型号未知，看设备树电压是1.8 / 3.0 V，
把vcc_sd从0x2dc6c0加到0x325aa0即可解决

你也有这块板子?咸鱼最便宜的3399...

麻烦传一下你改好的 dtb 我试试看,我试过修改电压 还是一样

[sjllls]

麻烦传一下你改好的 dtb 我试试看,我试过修改电压 还是一样

原因不在于dtb，尝试过以下内容:
1.直接刷入ophub的tn3399固件，无法启动
2.直接刷入ophub的am40固件，间歇性正常启动
3.直接刷入ophub的firefly的固件，无法启动
4.使用自己写的dtb替换am40固件中的dtb，能够启动
5.使用自己写的dtb替换firefly固件中的dtb，无法启动

如果说rk3399不同机型的rootfs仅仅只有dtb的不同，替换dtb应该是能启动的，但是试验结果来看不是这样

回头有空了再看看编译脚本有什么具体的不同
PS：很奇怪tn3399的固件无法启动，暂时没有接上uart，不然能看看uboot的log
