Dear all,
I flashed my BBB using Debian 2015-03-01 image.
And to my surprise, there is no MLO nor u-boot.img in the FAT partition.
Even more surprising for me, the BBB can boot without problem and proudly
displays :
U-Boot SPL 2015.01-1-gb2412df (Jan 29 2015 - 15:01:06)
on the console.
Thanks Gerald for the help... That worked and I can boot directly from SSD
card without pressing the Boot Button.
I have one little confusion though, the saveenv command saves it in MMC, I
would have thought that it should save in SD Card.
U-Boot# saveenv
Saving Environment to MMC...
Writing
Is there an update on this for the newer Debian on board BBB? I have the
uDev.txt info, the card is formatted and mounts on /media but the rest of
info I find seems to be pre-Degain. What else do I change so that the host
sees the card rather than the onboard memory?
Thanks
-Jim

No, that's incorrect, they are stored in the master boot record (MBR), 1MB

To clarify, I want the SDcard ti appear as a FAT drive via the normal host
USB connector. The online stuff I find refers to changing files and things
that don't seem to exist with Debain (unless I am missing something!)

You cannot do 24b and say 1920x1080 resolution. There is not enough memory
bandwidth. That is why it is 16bits instead of 24bits on the BBB.
If 24b is that critical, then you need to cut the resolution back. Also,
the pin mapping is different for 24b vs 16b. All the colors get scrambled.
You can
You want to use the USB gadget to export the SD Card filesystem. This is
similar to something I'm doing for an upcoming DEFCON talk. Here is the
script for that talk:
#!/bin/bash
# stop the GETTY service if needed
if which 'systemctl' ; then
systemctl stop serial-getty@ttyGS0.service

OK. So I finally got this all working (with the Debian Jessie RFS no less) by
exporting a file system for each target board. So overall directory structure
is something like this:

Hi All,
I am using BBB based custom board.
I want to print RAM(DDR) frequency information.
How can I print RAM(DDR) frequency information in Linux.
Any utility/tool? Somewhere in proc or sysfs or debugfs ?
Thank you,

I have a new BBB with Debian. I want the SD Card to appear on the USB port
(to Host) rather than the internal memory. I find references to uDev.txt

the pre Debain stuff. I have the card formatted and when I ssh in, I can

No quotes.
The above is persistent, and by its self requires a system restart in order
to become 'active' However you can also use modprobe to load the module
without a restart. Using the exact

Yes, others have experienced this problem. As I've seen a few post on
similar subject over the past couple years. While I can not say 100% what
will fix this issue for you, most of the posts I remember seeing seemed to
be with reversed, or swapped colors.

For what it is worth, and in case this might help. The screen resolution /
bitdepth I mentioned in uEnv.txt is a kernel parameter. So if you happen
across a post or article that mentions kernel params for screen resolution,
etc. uEnv.txt is how the uboot passes kernel params to the kernel.
