Getting Some problem of Emmc when I test my development board
My development board is imx508 ARM2 platform.This platform use the EMMC(SanDisk SDIN5C1-4G) as the boot device and storage device.I got some problem when I test it.
1.It take quite a long time when resume the system,about 145ms.That is unnormal.I have found out that the time is spent in mmc_init_card/mmc_sd_init_card(file:driver/mmc/core/mmc.c;driver/mmc/core/sd.c).But I don't know why,and I no sure the problem,driver,chip,hardware???
2.Sometime the device got a log like this:
mmcblk0: retrying using single block read
This may influences the system performance.And there is some way to get things done.
I hope someone give some suggest,Thanks first and Best Regards!
