[U-Boot] [PATCH 27/31] 8xx, mgsuvd: rename board to a more generic name
by Heiko Schocher 28 Jan '09

28 Jan '09

renaming the "mgsuvd" board port into "km8xx", because there will come more similar boards from keymile. Compiling the mgsuvd board with "make mgsuvd_config" remains.

Re: [U-Boot] U-Boot hangs after uncompressing kernel image on MPC5200B

Thank you for your reply Mr. Likely! I was indeed using the wrong image file. So I've tried the uImage generated by the kernel build, and it still hangs. It might be the addresses I'm using. I've read some FAQs sections that seemed to give me some hope, but they all were related to wrong RAM addresses or not related to device trees at all, just to the old cuImage booting procedures. Anyway, thanks for your interest, Mr. Likely. ----- Original Message ----- From: "Grant Likely" To: "Marco Antônio Possamai" Cc: "U-Boot" Subject: Re: [U-Boot] U-Boot hangs after uncompressing kernel image on MPC5200B Date: Thu, 22 Jan 2009 07:30:01 -0700 On Thu, Jan 22, 2009 at 4:05 AM, Marco Antônio Possamai wrote: > Hello, all. > > My goal is to succesfully pass a 2.6.26 linux kernel to the MPC5200B > using the three-argument command bootm.

If you want to use the 3 argument bootm (kerneladdr, rootfsaddr, dtbaddr) then you need to use the uImage produced by the kernel build, *not* the cuImage. The cuImage is a backwards compatible image for the older 2 argument bootm command. g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
