With relocation, you must set TEXT_BASE to the value you start the image, so please try to set TEXT_BASE = load_addr.
Also, if you do a ram image, don;t forget that with relocation the u-boot image gets relocated to the end of ram, so don;t choose a TEXT_BASE near the end of ram.
If that not helps, you maybe need a debugger ...

Hi Heiko,
I did see that, and thought it might have something to do with it. I also tried building a version with the TEXT_BASE at 0x100000, but had exactly the same result.
It sounds like a debugger will be my only option. Fortunately, I should be getting a Segger J-Link JTAG adapter on Tuesday, and then maybe I can figure out what is going on.

Hi Heiko,
It is clear now that I *am* an idiot.
I was loading the uImage to 0x100000, but the uImage was configured to be copied to 0x3000000 before being started by the vendor u-boot.
Setting TEXT_BASE to 0x3000000 allowed me to start my chainloaded "on top of master" u-boot.
Now all I need is to figure out the right way to patch the CFI code to handle my 8-bit/16-bit configuration, and I should be ready to submit a working configuration.
Thanks for your help.
Rogan
