Custom Board doesnt run with Angström Image

[El Smiedro]

Hello community,

I use the Angström Image v2012.12 - Kernel 3.8.13 with U-Boot SPL 2013.04-dirty (Jun 19 2013 - 09:57:14) and I can login on my BBB.

I also try to run a custom board similar to the BBB. I only removed the HDMI part and use a MT41K256M16TW-107 ITP DDR3. When I try to boot, it stops while running the kernel:

Could the different RAM be the reason for this? Could anybody give an advice to get it run?
Thank you very much.

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..

 Thank you for your fast reply.
I didnt remove anything. I only download this image: https://s3.amazonaws.com/angstrom/demo/beaglebone/Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.20.img.xz from BeagleBoard.org and put it on my sd-card.
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?
Thank you

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

YOU removed the HDMI..

What Nand?

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

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:

CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
U-Boot SPL 2018.01-00002-g9aa111a004 (Jan 20 2018 - 12:45:29)
Trying to boot from MMC1


U-Boot 2018.01-00002-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.

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?

[Robert Nelson]

Well they are stored in the MBR..

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

[evilwulfie]

Do the current images load capes DTBO files automatically when a proper
eeprom is detected?

uname -r
4.14.20-ti-r36


OR do we have to just load them in /boot/Uenv.txt

Be nice to take some of the configuration and automate things.

[Robert Nelson]

It does as long as your version of u-boot in the eMMC isn't ancient..

[Robert Nelson]

Oh sorry, i forgot our previous conversation:

https://groups.google.com/d/msg/beagleboard/kpKoeZf_yJ4/tuD9lFw-DgAJ

you don't want to update the eMMC..

So my solution doesn't work for you.
