[U-Boot-Users] Patches for 85xx question

[robert lazarski]

Hi all, I'd like to submit patches for our project 'atum' (Tuna in
Brazilian portuguese, its a custom to name projects after fishes) for
inclusion into u-boot. Its a 8548 based board. Should I base patches
off of u-boot 1.3.1 ,
http://opensource.freescale.com/pub/scm/u-boot-85xx.git , or some
other git repo?

BTW, thanks for this excellent community and all the help we received so far,
Robert

Hi Robert,

> thanks for this excellent community and all the help we received so far,

So does this mean you've managed to get Linux up and
running, no memory issues, etc? Congratulations!

Cheers,
Dave

Hey thanks, what a long strange trip its been ;-) .

For the memory issues, we found a memory chip (Micro 533MHZ) that
works 95% of the time, and the hardware guys are working with
Freescale support for our second revision, and in fact have already
improved things considerably on other chips. That's good enough to
continue the project ;-) .

The PCI issues were resolved also by hardware, via using "Asynchronous
mode" instead of "Synchronous mode", thereby routing CLKOUT to
PCI1_CLK. See the "4.4.3.17 PCI Clock Selection" section if
interested.

So the latest 2.6.24RCx kernel's now booting, and all that's left is a
few driver issues. That and submitting patches ;-) .

Cheers,
Robert

Hi Robert,

Sounds more like the trip you should have expected.
That'll teach you for being optimistic, eh
I get burned for being that way too - an engineering
trait I guess.

Feel free to provide details on your solutions.

The Freescale design documents are sparce in some places,
incorrect in others. AN2931 which contains the design
recommendations for boards based on the 83xx series processor
has been revised multiple times since I started work on my board.
And even now, there are other valid ways to implement parts
of the design.

So you have clocking issues?

Glad to hear your 'Tuna' can swim.
Sure beats being stuffed into a tin can :)

Cheers,
Dave

Use the u-boot-85xx.git tree on denx.de.
