I told you, several times, and I repeat it here again, for the last time, promised: If you want to have an easy start, use a separate device tree. This is what has been tested all the time, and what is known to be working. If you go for cuImage, this is completely untested code on TQM8xx, and you are on your own - this may work, but it is more likely that it doesn't.

You already updated U-Boot successfully, so there is no need to continue trying cuImages. But it's your choice.

You don't have to use the most straightforward way that has been well tested for a ton of combinations of recent U-Boot releases against recent kernel releases. You are free to chose any untested, unsupported way you like. It's perfectly fine to ignore all good advice you get here.

Because this code has never been adapted for nor tested with any TQM8xx boards? But frankly, who cares? This code simply is not needed for these boards.

What you say boils down to: Please help me, but don't mention the
solution, because I'm not going to do that. In short, it's stupid.
You are wasting your time, and ours.
In the first step, please update your U-Boot. 0.4.0 has no support
for device tree.

In the cuboot section of arch/powerpc/boot/wrapper, add "*-tqm8xx" to the "*-mpc866ads|*-mpc885ads..." list. -Scott ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] having trouble booting a simple kernel on a TQM860 board
(since it's been a while since i've had to mess with u-boot, it is entirely possible that i'm doing something amazingly dumb but here we go.) i've got two different types of PPC boards in front of me -- some lite5200's and some tqm860's -- and all i want to do is verify that i can build a kernel for each, TFTP it down to the board and boot that kernel. i don't care that it will fall over when it tries to mount a root filesystem, i just want to see the early kernel boot output to verify that at least that part of the process is working. i'm using the 2.6.37 kernel for both and while the lite5200s have a fairly new version of u-boot (2010.12), the TQMs have an ancient version (0.4.0, possibly slightly newer), and i have no freedom to update those so don't even make the suggestion. i just have to live with that. the lite5200s are no problem. with them, i just: $ make ARCH=powerpc 52xx/lite5200b_defconfig $ make ARCH=powerpc and eventually, i get arch/powerpc/boot/cuImage.lite5200, download that and go. so the lite5200s are not an issue. with the tqm860's, i'm following some documentation that was given to me that allegedly has worked in the past, so i run: $ make ARCH=powerpc tqm8xx_defconfig $ make ARCH=powerpc uImage what i get in arch/powerpc/boot is: $ file uImage uImage: u-boot legacy uImage, Linux-2.6.37, Linux/PowerPC, OS Kernel Image (gzip), 1301506 bytes, Fri Dec 2 18:08:06 2011, Load Address: 0x, Entry Point: 0x, Header CRC: 0x476FD0BD, Data CRC: 0xE355BE2A $ $ mkimage -l uImage Image Name: Linux-2.6.37 Created: Fri Dec 2 18:08:06 2011 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size:1301506 Bytes = 1271.00 kB = 1.24 MB Load Address: Entry Point: which *seems* all right, but i'm not a powerpc expert. so i copy this to the TFTP dir under the name "uImage.tqm860", and on the board: => tftp 40 uImage.tqm860 TFTP from server 192.168.202.100; our IP address is 192.168.202.79 Filename 'uImage.tqm860'. Load address: 0x40 Loading: ... snip ... done Bytes transferred = 1301570 (13dc42 hex) => i can check that the download worked: => imi 40 ## Checking Image at 0040 ...

OK => and, at this point, i would think that all i need to do is: => bootm 40 ## Booting image at 0040 ...

OK Uncompressing Kernel Image ... OK and that's where it hangs. i have no idea if it's still booting properly but i've simply screwed up the serial port setting. does this set of steps look reasonable? the configuration, the building, the TFTP, the verification steps, the "bootm" command? this is what's printed when the board resets: U-Boot 0.4.0 (Apr 13 2004 - 15:01:22) CPU: XPC860xxZPnnD4 at 80 MHz: 16 kB I-Cache 8 kB D-Cache FEC present Board: TQM860LDB0A3-P80.208 DRAM: 16 MB FLASH: 8 MB In:serial Out: serial Err: serial Net: SCC ETHERNET [PRIME], FEC ETHERNET PCMCIA: No Card found am i just missing something obvious? what should i use for the kernel console setting? i'm open to suggestions. rday -- Robert P.
