[U-Boot-Users] [PATCH 0/3] PPC:...

Thanks for all your suggestions. I've used the environment to do the auto-booting after enabling the CFI driver for environment storage to FLASH.

One of my important targets to use u-boot is to let my board be able to boot Linux kernel as the following way: 1) Power ON 2) VxWorks Bootrom started from FLASH 0xFEF00100 3) Start U-Boot (BIN) from FLASH 0xFEFC0000 4) U-Boot starts Linux/Initrd/DTB following the command line configured in VxWorks Bootrom (this is still not resolved yet)

Finally, my VxWorks bootrom can be selectable to boot a normal VxWorks image or a super package including Uboot and linux. And vice versa, if I put the U Boot's FLASH address as the CPU starting entry point, the u boot can also be selectable to boot any kinds of images.

Best Regards, Tony

I'm very, very far from being a device tree expert and am not up to date on the wonderful FDT work that Jerry Van Baren and friends have worked on over the last several months. AFAIK, there's no way around having the kernel and device tree as separate images. If both truly

Actually you should be able to use a (classic) multi-file image, although I have to commit that I haven't tested this for a long time.

Or, you can wait until the new image format gets merged in the next version of U-Boot (patches have been posted, you are welcome to give them a try).

need to be dynamic, of course you're going to have to download both each time. You can certainly minimize the amount of human interaction by scripting U-boot to automatically TFTP the blobs to pre-defined addresses and then boot from there.

right. You just have to type the commands once and save them as an environment variable which you can then "run".

Why are you making all this so complicated? What do you need the VxWorks Bootrom for? Just install U-Boot in flash, and let U-Boot boot either Linux or VxWorks.

Hi,

I add a few change and an older version on u-boot for support ide on arm (about 10 lines of codes). The changes are made in cmd_ide.c file, and arm/board.c. I think that is not present in the latest version of u-boot, it is right?

Indeed. There is no magic way for your code to make it into the public source tree without you posting proper patches first.

This has coding style violations, your signed-off-by line if missing, and it was line-wrapped by your mailer.

Sorry, but please retry.
