Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit
Robert, In your last post you suggested downgrading to 3.8.x so that I can use the capemgr to enable the BB-UART2-00A0.dtbo device tree overlay. But before I downgrade, is there an alternative way to enable UART2 that will work with 3.14.X? I'm using an XBee cape board that needs UART2 enabled. Whatever method I use to enable UART2, it must work automatically at boot time so that my cape board works after booting without intervention from me. By the way, I noticed that /dev/ttyO2 is present on my 3.14.X image, so I tried simply plugging in my cape board to see if UART2 worked, but no luck.

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit
Robert, I installed Ubuntu (not Debian), by following your instructions for copying the raw microSD image to the microSD card: http://elinux.org/BeagleBoardUbuntu#BeagleBone.2FBeagleBone_Black Then I inserted the card in the BBB, held down the boot button while powering up, and it booted from the card. If I reboot, it boots from the microSD card, which is what I want. If I remove the card and power up, it boots from the eMMC. Do I need to flash anything to the eMMC? The eMMC still has the default Debian. Since the BBB boots from the card as desired, maybe I don't need to do anything to the eMMC. I have one question. I will be using a XBee cape board that needs UART2 to be enabled. I will need to add a line like this to uEnv.txt: optargs=capemgr.enable_partno=BB-UART2 I think I should add this line /boot/uboot/uEnv.txt in the eMMC, am I right? I ask this because the microSD card has two copies, /uEnv.txt and /boot/uEnv.txt. The contents of these two files and the file in eMMC are different.

Robert, I haven't actually written the Ubuntu image to eMMC yet (I have on the first five BBB's but not on the sixth, I can't get past step 1 on the sixth). This is my goal. 1. Get Ubuntu installed on a microSD card. 2. Configure the BBB to boot from the microSD WITHOUT pressing the boot button every time it boots. I really don't care what version of Linux is in the eMMC, I just want the BBB to automatically boot from the microSD card. The BBB will be accessed and rebooted remotely, without a human present to push the button. I will look at the links you provided. Will the instructions on the links you provided help me reach my goal?

Okay, so this was self-inflected... At this point where you copied the
ubuntu image to the onboard, eMMC, well i'd contact "armhf.com"...
If you are using images from:

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit
Robert,
Holding down the boot button doesn't work, I get the "Bad Linux ARM zImage
magic" error mentioned above.
When you say it has a later version of u-boot, do you mean the eMMC has a
later version of uboot than my microSD card?
How would I fix my uEnv.txt? Here is my uEnv.txt script from the microSD
card (which is different than eEnv.txt in the eMMC):
mmcpart=2
mmcrootfstype=ext4 rootwait
optargs=fixrtc capemgr.enable_partno=BB-UART2
uenvcmd=i2c mw 0x24 1 0x3e; setenv mmcroot /dev/mmcblk${mmcdev}p${mmcpart}
ro
loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}
loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}
Remember, my microSD card has Ubuntu 12.04.5 LTS
(ubuntu-precise-12.04.3-armhf-3.8.13-bone30.img.xz downloaded from
http://www.armhf.com/) and my eMMC has the default Debian that came
installed on the BBB.
Here is what I've done
1. Copy Ubuntu image to the microSD card (as per
http://www.armhf.com/index.php/getting-started-with-ubuntu-img-file/)
2. Plug card into BBB and boot from card by holding down the boot button
3. Copy Ubuntu image to the onboard eMMC
4. From that point forward, BBB will boot from microSD card without having
to hold down the boot button.
I have six BBB's. I followed these steps for all six, and it worked with
the first five BBB's. It's only the sixth BBB that is giving me this
trouble. The sixth refuses to boot from the microSD.
Thanks for your help Robert, I'm just not sure how to get this sixth
beaglebone working.

It's not "defective", it just has a later version of u-boot... Either, hold down the boot button to boot with the microSD card, erase the bootloader in the eMMC or fix your uEnv.txt script..

Sorry, nope. From bootrom -> u-boot, it's serial only. While there is early fb support in u-boot, we don't currently utilize it yet..

You do not log in via the UART( serial ) console until the OS is loaded, and in a running state. Just before this happens, you will see the kernel boot "log". When the board first comes up, and uboot has control of the UART. It should start spitting out information related to what uboot is doing. *IF* you get nothing but "C . . ." then this means uboot was unable to find a suitable image to load. *I'm trying to determine if getting an FTDI cable will help debug this > failure to boot problem.* > You really do not have any other option. Aside from not bothering with it. But honestly, how many boards did you say you have ? If you plan on doing anything project wise with the boards. A serial debug adapter is pretty much a requirement.

Robert, could I connect a keyboard and monitor and see the boot messages on the monitor, the same boot messages that would appear on the serial console? I'm asking because I could connect a monitor today, but I'd have to order a FTDI cable, which would take a few days to arrive.

By having the FTDI cable plugged in, you'll visually see over the usart the full boot procedure and either the software error or hardware failure of the microSD.. One can easily be fixed, the other is a broken board. Till then, the 4 led pattern doesn't tell us much.

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit
@Tim On Windows puTTY is probably your best bet. I'd say that *everyone* who uses COMx devices on windows use it, but I'd probably be wrong. There are many apps out there. But puTTY and the paralax serial app are the two most prominent on my mind. So basically, you get an adapter, be is cable, or otherwise. You install the drivers for that cable on windows. Look in hardware manager find the COM port the drivers reserved for the device. Then you install puTTY, change the connection type to serial, and then you must configure the connection ( COM port, baud rate, parity etc.) Anyway, I'm sure there is a how to on the web somewhere. I used to have one on a forums for the beaglebone black when it was first released. But it seems now that forum is defunct. Just make sure you use a 3.3v TTL adapter . . . otherwise you'll probably damage your BBB.

Yes It should boot from the onboard emmc. Type “debian” as the username and “temppwd” as the password. Then try “dmesg” to see all of the boot messages.

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit
Gerald, I seem to be having a problem booting any image from a uSD. I originally tried putting other distros on the bbb when purchased back in Dec. Then I decided to just flash the eMMC with Angstrom, which seems to work fine. Now, however, I am incorporating the radium camera cape into a project and I cannot seem to boot with their modified Angstrom image, which apparently is required to be used via uSD because the cape interferes with the eMMC. Trying to boot from this and any other image produces user LED activity for about 3-5 minutes, and appears to be booting from uSD based on lights. Then suddenly without warning, the LED activity stops and the 2 middle user LEDs stay lit solid, along with the pwr light. I know this is related to power failure in other cases, but wondering if that is the same issue here? I have been using a combination of bench top and wall wart pwr supplies, all rated at 5V/2A. Any thoughts? Peter -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

I have one more question to ask. Please bear up with me. In the link that you have sent, I find that RMA can be filed only if the stock has been purchased from an authorized distributor. I am from India. Here we have three authorized distributors and all of them were out of stock. As we are hurrying up with our final year BE project we had to buy one from another online shop.

Thanks I was following William Hermans post. uEnv is the boot program which
links into the image folders so the uEnv program has had no problems which
is good to know. I will try the step by step approach.

I¹m not sure why you want to make these changes in uEnv. If the SDCard is
installed, it is mmcdev=0 and eMMC is mmcdev=1. Best to use the default uEnv
file.
If you are unsure, you can always run each command at the u-boot prompt and
see what happens. You can list files in the FAT partition with ³fatls mmc 0²
and load the uEnv.txt file with ³run loadbootenv² and ³run importbootenv²,
which updates your u-boot env. Check this with printenv. Best way to learn
is to do this step by step.

John
