In order to exclude possible errors on my board, i get MarsBoard A20 Lite, desolder nand, and put on emmc pads my emmc flash. So emmc is on sdc2 lines. When iam booting from sd on sdc1, linux kernel can init emmc, and i got /dev/mmcblkp1, works well. But when i eject sd and try to boot from sdc2 emmc, get the same err 17. In this case i have used some old uboot from marsboard site, because mainline u-boot have not config for a20 marsboard.
U-Boot SPL 2014.04-10685-g4af825f-dirty (Jun 14 2014 - 17:55:48) Board: MarsBoard-A20 & MarsPI DRAM: 1024 MiB CPU: 960000000Hz, AXI/AHB/APB: 3/2/2 Card did not respond to voltage select! spl: mmc init failed: err - -17 ### ERROR ### Please RESET the board ###
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 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 CONFIG_MMC_TRACE
After run, got:

So, spl_mmc.c on line 66, blk_dread return 0 count blk.h on line 389, block_dev->block_read(block_dev, start, blkcnt, buffer) return 0 block_dev->block_read is a pointer, seems like it defined in mmc_legacy.c on line 144, bdesc->block_read = mmc_bread; mmc.c, line 285 mmc_read_blocks return Failed to read blocks mmc.c, line 223, mmc_send_cmd return 0, cmdidx was 17, like last in mmc trace

Emmc Card was the new one, so i just burn a dump of working sd. Previously sd have been wired to board for test.
Board is a custom, like olinuxino lime which with nand and sd slot, 512 mb ram. So i using it defconfig and in case of sd card, it works. Emmc lines has external pullups according to the datasheet.
Well, i needs to get more information..If you guess that seems to return 0 from block_read().. then you can find which condition was hit..is it impossible?
If you can share more debug message..then i will help you.

Like a sd card. I have emmc to sd adapter, so
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
I guess you cleaned[1] the card before doing this?
and then just solder emmc to my board.
OK, which a20 board?
