|New BeagleBoard Rev C5 Shipping||Gerald||7/24/11 7:16 AM|
For those of you buying the original BeagleBoards, we are now shipping the new Rev C5 version. Documentation can be found here:
The reason for the change was that Micron stopped producing the memory that we were using on the Rev C4. So, we had to change the memory. We will no longer be building the Rev C4 version.
This new revision results in a change being required to the UBoot and Xloader. As I understand it, you should be able to replace the UBoot and the Xloader and your current SW should work, but no guarantees. The board ships from the factory with a GNOME desktop in it and will boot to the desktop from NAND.
To get the new UBoot and xloader, you can create an SD card using the.img file from the link above and then create a new card using the Uboot and xloader from that SD card. Check back at the link above often for SW updates. We anticipate a newer release in the coming days.
If you have any issues please post your questions to the mailing list or IRC.

I just tried it and it works for me.

Google groups is prepending a 'google.com' to the URL. Remove that and
it works fine.

I am viewing it form GMAIL and it worksfine. Yes, indeed Google group is messing it up. You can just type in what you see and not click the link.

Is the Wiki correct: 512Mbytes NAND and only 256Mbytes RAM?
|Re: [beagleboard] Re: New BeagleBoard Rev C5 Shipping||Gerald||7/25/11 6:06 AM|
The wiki is correct. The orignal version was 256MB NAND and 256MB DDR.

The Micron MT29C4G48MAZAPAKQ-5 IT appears to require 4-bit ECC (please
correct if this is not accurate). Have there been any efforts made to
support this level of ECC in the beagleboard sw?

I will defer to the SW team on this one.

We are using the MT29C4G48MAZAPAKQ-5 IT Micron part on an OMAP3530 in
our custom design. It was necessary to modify the x-loader and u-boot,
because the old Micron PoP had two 128MB RAM parts, one on each chip
select line. The new one has only one of 256MB. However, no
modification to the ECC code in u-boot was made, so it seems that the
new part does not require any changes beyond this. Writing MLO, u-boot
and kernel from u-boot to NAND works just fine.

After reading up on the issue I realized that I didn't really
understand the problem (which I now do).
Cliff, could you give me any pointers on how you are using the Micron
ECC? Is this something you can enable during NAND init, or will I have
to patch the relevant ECC routines in the kernel to take advantage of

Attached are my current patches. While they seem to function, they
