2008-04-05 20:25:35     Help flashing u-boot to the BF561-EZKIT

Marshall Seaborn (UNITED STATES)

Message: 53691    Please help. I'm trying to flash the u-boot image (i.e., u-boot.ldr) to the flash of the BF561-EZKIT eval board. I'm using the ICEBear JTAG debugger with bfloader under Linux. I've set the boot mode to mode 0 SW3 positions 1 and 2 are ON and the following shows the result seaborn@123:~/Projects/u-boot$ flashload --eraseall --program=u-boot.ldr Dual Core CPU found Number of devices in JTAG chain: 2 JTAG wait cycles: 0 Previous Core fault at 20000000, trying to recover.. Detecting device... Detected Device: BF-561 rev:5 Detecting device... Detected Device: BF-561 rev:5 seaborn@123:~/Projects/u-boot$ What am I doing wrong? Thanks, Marshall

Please review and the datasheet.

Boot mode 0 is not expecting an ldr

Robin: Thanks for your reply.

 

I don't understand how to apply the information on the bootrom page to determine

 

the proper configuration of the BF561-EZKIT board for programming the flash.  Is there

 

a documented procedure that will guide me through programming the flash, with the ICEBear

 

JTAG programming tools?  (or any JTAG programmer for that matter).

 

I have built u-boot and I have .hex, .ldr, .bin, etc.  formats.  How do I program the board with

 

any of these images?

 

Thanks,

 

Marshall

Mike,

 

Thanks for your reply.  I'm trying to find out how to use the

 

ICEBear tools to programthe flash on the BF561-EZKIT board.

 

The document you referred me to seem to be specific to the IGLOO flash programmer

 

and the ADI flash programmer which use different software tools.

 

Thanks,

 

Marshall
