How soon will that patch be available (or the code submitted to the tree)? I have a custom board arriving at the end of the week that will have an 8360 rev2....and it has DDR2 memory so I'll need DDR2 support. Is there somewhere that I can download the latest bits to get started?

But before your mail, I was just looking in WD's git tree for the changes--I didn't know that freescale had its own git trees for u-boot. One question about the 8360 version. When I compile it straight up for the MPC8360EMDS_HOST_66 configuration, I never see any output at the startup of U-boot. But if I comment out the open firmware defines in the include/configs/MPC8360EMDS.h config file, then all works. Why doesn't this work for me straight up on the board it was compiled for? (This has been true for all U-boot versions I've tried for the 8360).

It's also useful to have avant garde mpc83xx users such as yourself get 'early access.' Ultimately, though, an mpc83xx tree should be hosted on denx.de. > > One question about the 8360 version.

Every version of U-boot I've tried to use, all the way back to 1.3.x, for the 8360 as well as the 8349EMDS, has had the same problem. And as soon as I comment out the OF stuff in the config file, all is well.

Yes. The device tree source is in arch/powerpc/boot/dts in the kernel. You compile that with dtc into a dtb, transfer the dtb to U-Boot via tftp, and then boot the kernel, passing the dtb as the third parameter. > I guess someone probably needs to point me to some "device trees > for dummies" info........

If you want your board to be self-contained, put the .dtb file in a flash sector. I expect this is how most people will use it 'in the field'. As Timur alludes to, the boot command is: bootm <kernel address> <initrd address> <dtb address> If you don't have an initrd, use '-' If you're still confused I'd be happy to help with the details. This whole U-boot/device tree/linux process is sorely lacking in documentation. The 'booting-without-of.txt' file is nice and all, but it's jibberish to people who are just starting out. Having figured this out the hard way, maybe I'll put together a 'for dummies' document. regards, Ben ^ permalink raw reply [flat|nested] 11+ messages in thread
