imx6ul can not boot from emmc

[wangzhigang]

hi everyone,
    we cann't boot from emmc (qspi,sdcard is ok),our env is :
hardware: imx6ull
emmc: SDIN7DP2-4G (4.5.1)
uboot version: imx_v2016.03_4.1.15_2.0.0_ga (mx6ull_14x14_evk_emmc_defconfig)

boot mode 1 = on
boot mode 0 = off
BOOT_CFG1[7-0] = 01110010
BOOT_CFG2[7-0] = 00000100 (eSHD2)
BOOT_CFG4[7-0] = 00000000

1、sdchard （eSHD1）and qspi is ok ,so ddr parameter must have no problem
2、could you tell me the right configs (BOOT_CFG1/BOOT_CFG2/BOOT_CFG4) when boot from emmc.

we found there are so many people have the same problem, please give me a hand!!!
Best wishes!

Hi wang

for emmc boot configs one can look at p.9 spf-28617 i.MX6UL EVK schematic

Schematics (1)
MCIMX6UL-EVK_DESIGNFILES
Design files, including hardware schematics, Gerbers, and OrCAD files.
i.MX6UltraLite Evaluation Kit|NXP 

Use mfg tool for emmc programming

i.MX Software|NXP

hi, igor igorpadykov‌

   thanks for your answer.

   1. yes, the  MCIMX6UL-EVK is our reference board, but the demo board have no emmc instend of sd card as default. 

   2. 

    BOOT_CFG1：

    BOOT_CFG2：

  the emmc config is complicate, our config is :

   BOOT_CFG1[7-0] = 01110010

   BOOT_CFG2[7-0] = 00000100 (eSHD2)

  is this ok?

   3. we will use the mfgtools for test.

Best regards
