eMMC bus test command failure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
    
	I got one issue on Linux V3.7 as following.
         > mmc0: switch to bus width 1 ddr 0 failed 
         > mmc0: error -110 whilst initialising MMC card

         After debugging and checking the source codes, we find that in mmc_send_bus_test function, there is no data timeout setting(mmc_set_data_timeout). After we add the timeout setting function, this issue is fixed, could you help confirm it? Thank you!




Best Regards,
