I've been swamped this week. I hope to pick this up with you next week. On Tue, Feb 28, 2017 at 4:06 PM, Ron Brash wrote: > Hello, > > Here is a list of things I have tried: The raw zImage (which is compressed > with XZ), various addresses from indeed load address

Hello, Here is a list of things I have tried: The raw zImage (which is compressed with XZ), various addresses from indeed load address 0x2300, entry at 0x23008000 (and the same), I've tried setting the FTD address since it sets itself neatly at 0x22f and change, which will probably get

Re: [U-Boot] Complete verified uboot example

Hello, Still for some reason - there is an issue with booting from the FIT. With a version of Uboot without the FIT related CONFIGs enabled; everything works. Here is me taking my zImage and converting it to a u-image ( I am not sure on the addresses) mkimage -A arm -O linux -C none -T kernel

Re: [U-Boot] Complete verified uboot example

Okay - it seems, after working my way through a bunch of the documentation and examples in /doc/uImage.FIT - I noticed a discrepancy /dts-v1/; /{ description = "Configuration to load a Basic Kernel"; #address-cells = <1>; images { linux_kernel@1 { description = "Linux zImage"; data =

Re: [U-Boot] Complete verified uboot example

I've never seen the kernel load address (the start address for copying the kernel image into RAM) being the same as the entrypoint address (where U-Boot jumps to begin executing the kernel). I'd expect the load address to be 0x2300. It looks like you are converting the zImage into a U-Boot

Re: [U-Boot] Complete verified uboot example

You set the load address for the linux image to the same location as the FIT. U-Boot verified the hashes on the FIT and then tried to copy the kernel over top the FIT. I assume you put the FIT in flash. Pick a location in RAM for the kernel's load address. On Mon, Feb 27, 2017 at 1:49 PM, Ron

Re: [U-Boot] Complete verified uboot example

The projects I'm working on are based on Yocto so I've been using the u-boot signing support that is built in there. I believe the magic you are looking for is in http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/uboot-sign.bbclass. Specifically, when you run 'mkimage -F -k -K -r

Re: [U-Boot] Complete verified uboot example

Hello all (and thanks Mr. Altherr for this insight), Excellent feedback and I agree that all of this needs to find a home either on the global docs on the website and/or the text-only documentation. Regardless, this leads me to a few questions. NOTE: the use of a uboot control DTS, control DTB

[U-Boot] Complete verified uboot example

Hello all, I am adding verified kernel support on a board we are using and I am struggling to fully understand all of the concepts and steps required to pull everything together (on ARM, using ZImages and booting with a working DTB on 4.4.3x). I also looked at the test script inside of examples,
