Activate SD_mmc2 on Olinuxino A20

[Gogolator]

Hi,

I install debian on NAND of Olinuxino A20.
Now i put a SDHC 32Go class 4 in the large connector SD_MMC2.
And I see nothing in "/var/log/message" and no new device in "/dev"
When  I put a micro-SD in the small connector SD_MMC1.
I see the value of a device in "/var/log/message" and a device in "/dev"

Do you have a solution?

Thanks,

Laurent
