Bricked QSB pretty quick

AaronLinsdau — Tue, 14 Feb 2012 06:38:57 GMT

Is there a procedure available to reflash the micro-SD card that comes with the QSB? I was trying the LCD but it was defective. As a consequence, I wasn't able to shut down properly. After a few test cycles, Ubuntu doesn't load properly and during the startup, I get a kernel panic.

This makes developing software on the QSB a little tough!

Thanks!

I've done that as well once or twice by not shutting down correctly. My solution was to make a backup copy of the sd card using DD. Then if you toast the filesystem, just reflash the SD card with your backup image and you're good to go.

If you dont have a backup image, which is likely the case, then you will have to either build a new image using LTIB or download a working image from the net.

@Jesus - The bootup gets to the RPC trying to make a connection to the outside world and gets stuck. It keeps trying forever.

No, making a back up copy before embarking would have been safe. I downloaded the CF imager (Win machine) from

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab

Presumably the

L2.6.26_MX53_ER_1109_IMAGE_

should get me back up and working?

Funny, I've been doing embedded forever and yet going to a new platform (Linux) and CPU family is like starting over again.

I am only on a Windows machine at the moment since my quick start board is down. The demo images from

L2.6.26_MX53_ER_1109_IMAGE_

are downloaded. Now I just have to figure out how to burn those images to the micro-SD card in Windows. Any suggestions? Thanks!

Isn´t MFGtools a solution for you?

Re: Bricked QSB pretty quick

AaronLinsdau — Wed, 15 Feb 2012 17:50:33 GMT

I'll try the MFG tools for windows and use the iMX53 Linux .bin file in the

L2.6.26_MX53_ER_1109_IMAGE_

file tonite.

Ok, so I've tried loading the uboot image using cfimager but no luck yet. Clearly there's more than just loading a u-boot image, guessing what it is and hoping the parameters are right.

I've taken the L2.6.35_11.09.01_ER_images_MX5X.tar.gz file, unpacked it, chosen u-boot-mx53.bin and then put that in the directory with CFImager.v1.7.3.001_bin_2bsrc.zip, all downloaded from http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab

then run the command

cfimager -raw -offset 0x400 -skip 0x400 -f u-boot.bin -d e

where e is the drive letter of my micro-sd card. Plug that into the QSB and nothing happens. Okay, so there are far more steps to the Linux learning process.

Re: Bricked QSB pretty quick

daiane_angolini — Thu, 16 Feb 2012 17:46:43 GMT

Or you can use mfgtools and copy everything you want, only choosing the updater profile, can´t you?

I don´t understand why you´re trying to copy only u-boot..... =(

You can always take an Ubuntu live CD and flash your SDCard with 3 or 4 command lines ;)

Re: Bricked QSB pretty quick

AaronLinsdau — Mon, 20 Feb 2012 22:03:46 GMT

I've attempted the mfgtools for windows but the USB device for the iMX board doesn't appear. The drivers seems to load, though the board doesn't show up in devices.

The serial port reports "usb wakeup is here" with my partially corrupted image uSD card. But when in the MFG tools, there is no device that shows up. The serial port eventually gets to FEC: Link is down 7809 and then starts reporting a string of "T".

I'm not only trying to copy u-boot but anything else I need. The CF tools readme say that only *.nb0 files can be flashed to the uSD card.

This sure is difficult to get back to writing an application.

I've used the MFG tools with the following process :

1. Do not insert a Micro SD card into slot 1.
2. Plug-in the power supply. Connect a USB cable between PC and USB OTG port
on the i.MX53 START board.
3. Press the “POWER” key and ensure that the LED turns blue, indicating that the
board has been powered.
4. Open “MfgTool.exe” and ensure “Freescale i.MX53 USB BulkIO Device” is
found.
5. After the USB device is found, insert MicroSD card. Start MFG tool operations

and I was able to get a login and penguin but not past that. The lucid/lucid login doesn't seem to work and after a while, the penguin goes away from the VGA screen. I did receive the error during startup:

The user name of "root" with no password gets me into the system. Still no GUI...

I copied the entire file set contained in:

"L2.6.35_11.09.01_ER_images_MX5X.tar.gz"

into

"..\manufacturing tool\Mfgtools-Rel-1.6.2.042\Profiles\MX53 Linux Update\OS Firmware"

overwriting what files were in there from the installation of MFG tools. The process begins just fine but when the info "Jumping to OS image." pops up in MfgTool, the system stalls. This is where the "freescale login: " prompt appears at the serial terminal. It stays there forever.

So just copying the files from the downloaded image into the MX53 Linux Update folder doesn't quite work. Are there some other modifications required, then?

When the mfgtool is downloading, the USB port eventually disconnects from the computer. This happens with the default image from mfgtool, too. But the system doesn't halt. Eventually the message

failed to run command: type="find" body="Updater" file="" timeout="180" onError="" text="" ,, Error code:-65530

pops up during programming.

Mark,

What is DD? Assuming I get a working image back on the uSD card, I'd like to be able to make a backup.

Sorry, guys but for me, it worth the time to install an Ubuntu machine, or even a virtual machine.

I reflash the SDcard something like 500 times a day! And it take me around 3 seconds to get a new u-boot copy into the SDcard.

Finding a new SDCard tame me more time than copying u-boot....

dd is a command, and it copy anything to anywhere. It´s not a file transfer, it looks like memory copy

To copy u-boot on sdcard you even need it partitioned:

$ sudo dd if=./u-boot-no-padding.bin of=/dev/sdX bs=1K seek=1

to copy uImage:

$ sudo dd if=./uImage of=/dev/sdX bs=1M seek=1

For the root file system, it takes more time because it´s a big transfer....

If you have a Ubuntu machine, you can even build (and configure!) your own uImage.

Why don´t you give it a try?

Re: Bricked QSB pretty quick

AaronLinsdau — Wed, 22 Feb 2012 02:07:53 GMT

Daiane - I'll pick up a Linux machine. I'd like to get to programming rather than fooling around with images.

I have to connect to a camera and some control switches on I2C and want to do that. I'll have to reconfigure the image I'm sure and burning time just getting the basics going is a killer.

Re: Bricked QSB pretty quick

RandyKrakora — Mon, 05 Mar 2012 04:27:04 GMT

Aaron,

You don't need a linux machine, just a virtual machine ( VMWare ) that runs Linux. The VM runs on your PC under windows and it runs full Ubuntu ). Using this VM, you can write SD card as if you are on a Linux machine ( using dd command ).

If you look in the BSP docs .gz file, there are instructions for writing SD cards with everything you need to boot the QSB.

Here's a site that may help you get the VM set up to do Linux work, even if you plan to do all your development on the QSB, a Linux VM ( with a big disk ) will help.

Randy,

I'll have to try that. I ended up with a Linux box but it doesn't have an SD slot, so I'm using a USB SD reader - a thumb drive. I haven't figured out what device that ends up being in the /dev directory, so making dd work has been a challenge. I tried it against the mounted folder but dd didn't like that, saying what I was trying to copy was a folder rather than a device.

Re: Bricked QSB pretty quick

Probably /dev/sdb - dmesg should show you what it is after you insert it.
