beagle and u-boot v2?

[Robert P. J. Day]

just trying to catch up with recent developments -- what's the deal
with the beagleboard and using the current dev branch of u-boot v2?
if that's usable, i'll just migrate over and stop using v1. and what
are the plans for the next release of the BB? would u-boot v2 be too
leading edge for that?

I too am curious about this. I read the PDF overview of v2 a few days
ago and liked what I saw. I would like the most efficient boot loader
that includes USB and DFU, Inquiring minds....

Thanks,
Tyler

it's not so much the efficiency but if v1 is destined to be phased
out, and v2 is at least *usable* at the moment for the BB, there's not
much point investing any more personal time in v1. might as well just
move on and start using the next generation, *if* it's usable in its
current form.

Khasim is working on the new UBoot for the Rev C4 board.

excellent. so even if v2 is a little rough around the edges right
now, it's worth starting to use it to at least beta test it for the
BB and report any glitches. and where exactly would one report those
glitches? perhaps reports like that would be too BB-specific for the
general u-boot list and we should pass them on to khasim directly?

[Gerald Coley]

I would ping Khasim direct on this one.

Right now, that is planned to be based off of u-boot-v1. Nishanth has
done enough with u-boot-v2 to enable a nice, small image useful for
board recovery and I think there is a lot of potential for excellent
u-boot-v2 support of BeagleBoard, but I don't feel a big community
shift away from u-boot-v1 yet. The licensing of u-boot-v1 as GPLv3,
however, could quickly drive need for u-boot-v2 support for commercial
products. I'd be happy to hear some feedback here regarding what
should be shipped on the boards.

Khasim isn't working on u-boot-v2 right now, so best to put them right
here on this mailing list and likely CC the u-boot-v2 mailing list. I
know some people complain about the volume of traffic on this list,
but I think the threading has been pretty good and the noise here
isn't really bad. It is a lot nicer to read about u-boot-v2 than to
read posts that are answered in the wikis and FAQs.

I wonder what Khasim is doing for C4?

C4 board detection patch is available at

http://groups.google.com/group/beagleboard/msg/d039898a9bf9afb3

I asked for testing already 4 weeks ago, but got no (testing) feedback.

U-Boot v1 2009.11 is expected to be released soon. My plan is to send
this patch for mainline inclusion as soon as merge window opens (and
patch is tested).

Best regards

Dirk

And the processor frequency and voltage settings are different as well.

It would be nice if you could publish the detailed (new) settings
then. This would help (the community) to update U-Boot (and every
other boot loader people might use) accordingly.

It would be nice, too, if somebody with a C3 (and C4 prototype?) could
test

Many thanks and best regards

As soon as the settings are set we will get them out.

I just figured out how to generate 12.288 MHz out of the 26 MHz clock
(13 MHz SYS_CLK) using DPLL4. This clock replaces the
PRM_96M_ALWON_CLK 96 MHz.

So what will be the new processor clock frequency?

Now when my DPLL4 N/M frequency is 614.4 MHz and I divide it by 5 with
M2, which values should I program to M3, M4, M5, and M6 to cause the
least of disturbance to the rest of the board? In other words which
frequencies are DPLL4_M3X2_CLK, DSS1_ALWON_FCLK, CAM_MCLK, and
EMU_PER_ALWON_CLK supposed to be and what will happen if they are up
by 28 percent?

Fine thanks, I'll be waiting!
How were they on C3?
Do I understand right that OMAP3530 is the same as OMAP3430 with just
some phone modem related things dropped?

[Gerald Coley]

The OMAP3530 and the OMAP3430 are based on the same silicon.

just catching up here ... so what's the status of u-boot v2 on the
*c3* boards? is v2 usable? i can test that later today. is that
what some folks are looking for? more testing of v2 on the c3 boards
to speed the process along?
