TX1 SD card power enable


I want to know how to set the effective level of SD card power enable, the demo board is high level, but our board is low level, so I want to change it.

Our BSP version is R24.2.1, please give me some advice about how to change the regulators?


Hi cloundliu,

I interpret your question as the GPIO enabling the SD card regulator is not active high. The Device tree regulator entries for your board need to be updated. If your board is different there must be changes in device tree regulator settings. Please check the SD card regulator device tree settings for your board.


Hi b2,

I am so sorry for such long intervals between my reply, I have solved this problem.
