Hi,
We are working on sdk7.2 linux environment.
The following is our emmc settings in uboot dtbs, only "ti,otap-del-sel-legacy = <0x0>;" work fine on our plarform.
we want to use hs200 or hs400, the settings as below, but the uboot report "no mmc device at slot 0"
hs200 :

The following is the emmc supportability, hs400:1.8v and hs200:1.8v are supported.
We hope hs200 or hs400 can work on our platform, please give me a hand to trace it.
