2010-06-09 16:41:04     BF548 Board not booting with u-boot

Hi,

 

I'm trying to get u-boot working on my BF548-Ezkit and it's not working.

 

I followed the following steps listed on the BF548 page (http://docs.blackfin.uclinux.org/doku.php?id=hw:boards:bf548-ezkit#u-boot_installation_and_session_startup).

 

I am able to build the uart version of u-boot and install this on the board. I can then connect to the board and copy over the flash version of the u-boot and write it to flash (following the above instructions).

 

Switching the boot mode to 3 (SPI boot mode), I reboot the board and get no response either from the serial connection, and no penguin on the display. I booted the SPI-mode U-boot to verify it works - and it appears to.

 

I've retraced the steps several times but to no avail.

 

Has anyone had any similar problems, or can offer any advice next steps for debugging what went wrong?

 

The ez-kit is new out of the box, so I'm (assuming) that the jumpers are all correct.

 

 

 

Cheers,

 

Dave.

latest svn trunk is sometimes unstable.  use the release versions and you wont have to compile u-boot yourself at all.

I tried the latest trunk and the 2009-11 folder, both failed.

 

I'd like to figure out what's not working rather than just use the released version, so debugging suggestions would be good.

 

But that does remind me that I haven't tried the release version of u-boot yet. I should do that to determine whether it's the hardware or my build of u-boot.

First debugging suggestion - Start with a pre-build binary - to make sure the download/programming process is OK - then move on to the build your own from source...

the svn trunk has known issues atm, so having people debug it other than me is a waste of their time.  the release version is known to work.
