2008-03-12 09:53:22 uImage error BF548

Patrick Mc Donnell (IRELAND)

Message: 52389 Hi,

I have followed the steps given on the the website for downloading u-boot to the BF548 as shown:

Boot over the UART and write U-Boot to one of the flashes

build U-Boot with BFIN_BOOT_MODE set to <BFIN_BOOT_UART in <code>include/configs/bf548-ezkit.h

set the Boot Mode to UART boot (SW1 to 7)

Load it over the UART.

build U-Boot with BFIN_BOOT_MODE set to BFIN_BOOT_SPI_MASTER in include/configs/bf548-ezkit.h

set the Boot Mode to SPI Boot (SW1 to 3)

reset the board

Now when i tftp down my kernel i get the following error as shown in file attached.

I also get the same error when i port the uImage given on the website down to my board.

What am I doing wrong?

Thanks,

Patrick

Message: 52394 what source tree are you compiling ? what board are you using ?

you can just disable hard drive support in your kernel to work around the issue

I am compiling uClinux-dist-2008R1-RC2 for a BF548-ezkit.

I understand that i could get over the error by disabling the HDD but i need the drive for my project.

I get the same error when i try boot the uImage that you compiled on the site too.

Thanks,

Pat

I have seen the same issue on other HD - but never the one that ships with the BF548 EZKit.

When I have seen it - it resumes booting if I wait 5-10 seconds (for something in the kernel to timeout).

Can you try that?

Thanks

It just sits on the last line:

physmap platform flash device: 00400000 at 20000000

I even left it for a few hours and when i came back to it, it was still sitting there.

Regards,

Pat

Message: 52464 there have been fixes to the hard drive since the 2008R1 RC2 tarball so you should test the svn branch

Message: 52468 Can you enable debug in the BF548 PATA driver? and repost the kernel output?

linux-2.6.x/drivers/ata/pata_bf54x.c

There are a bunch of dev_dbg that should get turned into printk if you have a "#define DEBUG 1" before the include to ./linux/device.h

Thanks

Don't build 2008R1-RC2 for bf548-ezkit. There is a bug fixed against bf548-ezkit after RC2 is tagged. Please use the 2008R1-RC5 or wait for the finial release.

Message: 52541 Robin,

I have entered that line of code but from what i can see the kernel output is the same, which probably means i have done it wrong. I have attached both the kernel output and my pata_bf54x.c file.

I also downloaded the file uImage-SVN-bf548-ezkit from your site (nightly snapshots) and it ran through perfectly

I am looking for uClinux-dist-2008R1-RC5 as sonic said but i can't find it on the site, i can only find RC1 and RC2.

Regards,

Pat

Just check the kernel out from svn branch.

try moving the define to the top of the file.
