imx6dl sabresd uboot can not find MMC device

[wenmingfeng]

I have a customer board reference to the imx6dullite sabresd board. When I setting it boot from SD card. The uboot is up. but the uboot log show no mmc card found. Anybody else has similar issue?

The uboot is i used is uboot-imx-rel_imx_3.14.52_1.1.0_ga, command I used is make mx6dlsabresd_config.

Thanks!

Hi Wenming

one can check basic emmc functionality with attached baremetal test

from sdk (please create service request for obtaining full copy), run it

for example with jtag. Recommended to check emmc signals with oscilloscope.

Best regards

Thanks Igor for your quick sense. I am not going further to verify the internel emmc yet. Currently I can set boot device as SD, and the uboot can run, the serial port can print what happend. So I can using uboot do basic debugging, when I load the zImage and dtb into ddr, The CPU panic at can not find the VFS. below are the print log on console.
