Some summary
Marsboard by default has nand flash chip on sdc2 lines, but under nand chip,
there is emmc bga pads also.
So i have desoldered nand, and put emmc chip on it. Maybe there is no required
pull ups on data lines to work on 4-bit widh,
and when i boot kernel from sdc0 sd card, kernel
So, this debug output.

I decided to check how linux kernel init emmc on marsboard, which i boot from
SD card
And i found, that it inited only in 1-bit mode, is it normal? it works, i can
edit files on it
linux set
eMMC(sdc2) to mmc0
SD(sdc0) to mmc1

When i define CONFIG_DEGUB, u-boot binary size is to large for a20 sram
I have tried to disable unused features in config, but its not enough

Yes
Now i have checked det pin on my board. I use standart
A20-OLinuXino-Lime_defconfig with my board.
So PH1 is pull-fown. No changes if just remove det pin

So, the problem with eMMC KLM4G1FE3B-B001 is exists(
Maybe you know some cheap emmc, which is 100% works with mainline u-boot?

Hi!
Very appreciate your help! Hope we will fix it, because my board will be
garbage without emmc (
So, my steps:
git clone git://git.denx.de/u-boot.git --depth 1; cd u-boot;
make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime_defconfig
make CROSS_COMPILE=arm-linux-gnueabihf-
Also turn on
Already tried. The same output:

Hi!
I am trying to boot my A20 board from eMMC KLM4G1FE3B-B001, but has no success.
Commenting mmc_change_freq has no effect.
U-Boot 2016.03 just says Could not determine boot source
I have found, that it stucks in sunxi_mmc_has_egon_boot_signature.
int sunxi_mmc_has_egon_boot_signature(struc
