Utility for Booting and Flashing DM355 from SD Card (outdated)

This is great news; we will have to try it and provide feedback

Hi,

I am trying to boot from SD Card using this procedure but is not right. I don't know why. The board doesn't show nothig when I power up it. Do you know if this procedure is really correct?

I have my board based in the DM355 EVM that use the DM355 of course. I need to boot from SD Card because I don't have the Ethernet controlller yet...

Thanks

I have not tried this myself for the DM355 but I have worked with the OMAP3 and booting SD cards. One of the common issues is the SD card itself, it may be worth asking Constantine what particular type of SD card he is using, how large it is, the manufacturer, etc, as there could be some dependency on the card itself, as I have seen cards that do and do not work well when attempting to put an image on them in the OMAP3 case.

The images I used with OMAP3 were much larger than this one, they were the exact size of the SD card (2GB), of course the OMAP3 bootable SD cards have full blown file systems on them, so there is much more data and the entire card is effectively used by the partition(s). This being said, my next guess would be some issue with writing the image to the card, though the way Constantine suggests doing it seems correct, in our case we used the dd command from within Cygwin in a Windows environment through. Hopefully Constantine can reply with some further ideas.

write me please (may be on e-mail const@linuxdriver.co.il ) what you do and what you get. And I could tell you what to do.

BTW, I going to release updated clean version with sources

I powered up ,but it has nothing on my screen.

1.I insert a 2GB SD card (Kodak) to my EVM.

2.Power up, I do "cat dm355_boot.sdcard > /dev/mmcblk0 ".

3.Switch SW7: left - up, right - down.

4.Power up, but it has nothing on screen.

By the way,can I store my file system on the sd card?

I tested this operations on PC, not on EVM yet.
I don't know why it doesn't work.
Try please to write SD on your PC.

You can store your file system with updated version with sources:

Constantine,

I've downloaded your tarball and tried to get an card formatted to boot and have encountered similar results to xrqun.

I've built my card on a Linux system running Uuntu 8.10.  It's the same system I do my other DM355 development on.  I've formatted the card, an SanDisk 1GB class 2, with the command:

./dm355_sd_boot format /dev/sdb

And installed your Linux files with the command:

./install_sample

When I use the card I've created in either an DM355 EVM or a custom DM355 platform, I see the same results.  If the board is setup to boot from SD and it is powered up without an SD card installed, GPIO 61 will pulse at 4 Hz.  If the formatted SD card is installed, you won't see the pulse, but the system appears to hang.  So that would indicate to me that the RBL is finding the UBL on the SD card and jumping into it and hanging at some point.

I'm going to investigate further and see if I can trace down what's happening.

Has anyone made progress on this yet?

I have followed the proced ures that Constantine suggested, but the DM355 fails to boot, just the green LED flashing at 4Hz.

I did tweak the scripts slightly as my linux box (Fedora 10) starts the SD cards as /dev/mmcblk0 with the partitions being p1 and p2 suffixes to this.

Not sure where to go from here as it's hard to figure out what the DM355 is doing and why it's failing to boot.

Any suggestions ...

I am prepared to put some effort into this as SD boot is a requirement of our project, so if someone could give me push in the right direction I would be most greatful.

Thanks

Brendan

When all is configured properly and all required ulutites are installed everything should work file. Please send me your script output, runing "set -x" before it.

problem is: dd: truncating at 5242880 bytes in output file `/tmp/sdc/dm355.dat': No space left on device
because configuration is not suitable for your SD.
I tested my script on 1GB and 2GB SD cards.

FIX:
change echo -e ",10,b,*\n,,,*"
to          echo ",,b,*"
( or to      echo -e ",20,b,*\n,,,*" )

This fix will make one partition on all SD instead of 10 cylinders partition
