Hi,

 

Iam trying to check the performance of the SD card on the LS1012ARDB, using a Sandisk Extreme Pro UHS-I sd card.

 

When I check the AUTOCERR_SYSCTL2 register of the esdhc1 I see the UHSM field is set to SDR12 (with and without data transfer):

 

root@OpenWrt:/mnt# devmem 0x156003c
0x00000000

 

The manual says that the LS1012A itself supports SDR104. My question is, does the RDB supports UHS-I mode? if yes how to switch the Linux driver to use it?

 

Thank you,

Zaid
