Active level SD card detect in U-Boot

Hi,

Due to a design error, my motherboard give an inverted signal (compared to Colibri eval board) for the SD card detect signal. In a first time, I inverted the active signal in my dts file and the issue was repaired when Linux is running. But I discovered that it is not the case in U-Boot when I want to update the Colibri iMX6 from SDCard (SD card not detected) because dtb file is not loaded.

Does it is possible that U-Boot read the SD Card without taking into account the signal SD card detect (as broken_cd do it in dts file)?

There is no device tree available for Colibri imx6 in U-Boot. To invert the CD logic or to ignore card detect IO one will to tweek the board file here.
