Thank you for the link.
I guess thats there is a check for the emmc in the uboot when I use: 
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_boneblack_defconfig
Is that right? Do you know in which file I could disable it?
Thank you for your help

Well they are stored in the MBR..

Re: [beagleboard] Re: Custom Board doesnt run with Angström Image

['Eric Schm.' via BeagleBoard]

I tried to build my own MLO and uboot.img with this commands:
- make CROSS_COMPILE=arm-linux-gnueabihf- distclean
- make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 
am335x_boneblack_defconfig
- make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4

I suppose that I have to build a custom MLO and uboot.img and put it on the 
boot partition. But after flashing the Debian Image9.3 I cant find a boot 
partition. And the only MLO and uboot.img I could find was under 
/opt/backup/uboot/
Could someone give an advise how I could boot the uboot?

I use a custom board similar similar to the BBB but without the HDMI part, 
and a different RAM. with NAND I mean the eMMC on MMC1. 
I tried the Debian Image9.3, but it stops after the RAM:


U-Boot SPL 2018.01-2-g9aa111a004 (Jan 20 2018 - 12:45:29)
Trying to boot from MMC1


U-Boot 2018.01-2-g9aa111a004 (Jan 20 2018 - 12:45:29 -0600), Build: 
jenkins-github_Bootloader-Builder-32

CPU  : AM335X-GP rev 2.1
I2C:   ready
DRAM:  512 MiB

I programmed the EEPROM like the one from the BBB. Is ist stop because of 
the missing eMMC on MMC1?

Thank you all for your advices.

What Nand?

Anywho, it's 2018, that 2012 image is EOL...

Do yourself a favor dont use Angstrom It has no support
development has stopped

Use debian. We have Excellent support here when using a modern OS

I didnt remove anything. I only download this image:

I'm new to this topic and tried to build an own uboot and linux kernel with 
the BBB configuration. But they stopped after the RAM-check. Then I 
noticed, that my NAND is not properly connected because of a hardware 
issue. I assume that it check for the NAND and stops, because it cant find 
it. Then I tried the angström image from beagleboard.org. But I cant edit 
it. Is there a way to edit it with the uEnv.txt or do you now where I can 
disable the NAND-check in a current uboot?

[Jeff Andich]

I just did a 10 second google and it appears like tda998x is related to 
HDMI which you pulled from your board.

Just a couple of basic questions:

1) Did you remove the HDMI from either/both the u-boot pinmux and/or the 
cape manager?

2) If you start with a console image, does this yield the same result?  

I'm assuming that the console image doesn't access the HDMI port, but I DID 
see what appeared to be plain text appear on the HDMI port before X-windows 
started up on an LXQT image, so I could be mistaken..
