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
Best regards
igor

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
