2009-04-28 01:12:45     Flash operations fail at async bank 3

Hello,

 

       I have a BF526 cutsom board and I use the  u-boot-1.1.6-2008R1. I have a 4MB flash on my board. I am able to perform flash operations using u-boot for the first three async banks (bank0- bank2) but when I try to access bank3, my board resets. i.e when I try 'flash erase 0x20300000 +0x100' , my board resets.

 

The four async banks are mapped as follows

 

Bank0 - 0x20000000

 

Bank1 - 0x20100000  EBIU_AMGCTL (0xFFC00A00) - 0x00FF

 

Bank2 - 0x20200000

 

Bank3 - 0x20300000

 

 

 

EBIU_AMGCTL0 (0xFFC00A04) - 0xFFC2FFC2

 

EBIU_AMGCTL1 (0xFFC00A08) - 0xFFC2FFC2

 

Please help.

 

Thanks

 

San

you should be using 2008R1.5, not 2008R1

 

the board should not just reset without any message.  did you disable all the debugging options ?  if you did, you shouldnt be surprised when you get no output.
