我的cfg.ini文件配置是：
[profiles]
chip = MX6Q Linux Update
 
[platform]
board = ARM2
 
[LIST]
name = SabreSD-eMMC
我的UICfg.ini文件配置是：
[UICfg]
PortMgrDlg=1

你好，请问你用的是i.MX6Q的哪款开发板？是SDB的还是SDP？

当你用 eMMC 4.5版本的时候会出现你上述所出现的问题：
mmc0: unrecognised EXT_CSD revision 6
mmc0: error -22 whilst initialising MMC card
 
但是你可以按照如下的代码来更改：
 
 
文件位置为:  linux-3.0.35\drivers\mmc\core\mmc.c:
/******************************* For JEDEC 4.41****************************/
        card->ext_csd.rev = ext_csd[EXT_CSD_REV];
        if (card->ext_csd.rev > 6) {            
pr_err("%s: unrecognised EXT_CSD revision %d\n",          
      mmc_hostname(card->host), card->ext_csd.rev);
                err =-EINVAL;
                goto out;
        }
/******************************* For JEDEC 4.41****************************/

楼主你好，其中platform 不用更改为ARM2 [platform] board = SabreSD 就好。
