Hello, everyone
I'm trying to apply my custom board with u-boot falcon mode.
(kernel version: 4.1.15_2.0.0, Yocto: krogoth)
These are the sites I referenced:
How to decrease boot time on iMX6 - i.MXDev Blog
Fast Boot Linux with u-Boot Falcon Mode – Embexus
ventana/bootloader/falcon-mode – Gateworks
But, still I can not change to boot in falcon mode.
Normal boot or console dosen't work.(Nothing print in console.)
Normal boot works but falcon mode boot doesn't work.
If I boot with falcon mode, nothing print in console.
I am booting with eMMC and I can't use the SD card.
I wonder two things.
1. What is right 'partition map' in imx6 solo sabresd board?
I tried all of site's partition map, but did not work...
2. How to bitbake using Yocto project for output of 'SPL' and 'u-boot.img'
I made 'u-boot.imx' with this patch but it can't boot with mfgtool.
Please help me, anyone!
Thank you

please first try to implement normal boot.
For custom board run ddr test
i.MX6/7 DDR Stress Test Tool V3.00
then update uboot *.cfg file with new ddr calibration coefficients found from test
mx6solo_4x_mt41j128.cfg\mx6sabresd\freescale\board - uboot-imx - i.MX U-Boot
Use linux documentation (Porting Guide, Linux Manual) from link
i.MX Software and Development Tools | NXP

Hi igor,
There was a mistake in the question.
I'm sorry I don't speak English well.
Normal boot works, but falcon boot does not.
Normal boot was first downloaded using mfgtool, and it can also be booted with NFS / TFTP.
Best regards
Dahyun
