Just took a quick look and the one thing that jumped out at me was your JTAG
speed. jtag_speed is a depreciated command ... it should be jtag_khz. I
too have a eval board based on a ARM926EJS core ... it is a Atmel
at91sam9260ek based board. The thing I ran into was my board initially runs
using the 32k clock which required me to use a setting of jtag_khz 4 until
all the required registers are initialized (Clocks, SDRAM timing etc.) and
then I could bump up to jtag_khz 3000 and it would work with my board.
Not sure that helps you but maybe my experience applies to your situation.
Regards,
Brian
