P4080DS NOR FLASH OS IMAGE LOAD

Hi,

I have P4080DS board. When I want to boot p4080ds from nor flash bank 1, I need to set SW 7[0100XXXX] and load related OS image. Then change SW7 to [0000XXXX] boots the board. Is there a way that without change SW7 configuration load OS image correctly for all nor flash banks?

For example set SW7 to [0000XXXX]  then load os image to boot region 5.(To do that I need to know relative addressing for boot region 5 while SW7 [0000XXXX] ) After that set SW7 to [0101XXXX] then boots to board? Is this possible?

Best regards.

Only 2 bank configurations are supported in the Linux SDK: current and alternate - refer to the SDK documentation:

Submit Form

Note that it is not reliable to have more than two configurations because the NOR Flash size is 128MB and Linux distribution precompiled images consume about 37MB.

Example for 768kB U-Boot mapping with base address 0xeff40000:

SW7[2-4]

Start address

End Address

000

0xeff40000

0xefffffff

current

001

0xeef40000

0xeeffffff

010

0xedf40000

0xedffffff

011

0xecf40000

0xecffffff

100

0xebf40000

0xebffffff

alternate

101

0xeaf40000

0xeaffffff

110

0xe9f40000

0xe9ffffff

111

0xe8f40000

0xe8ffffff

SW7[2] -> 0x0400_0000

SW7[3] -> 0x0200_0000

SW7[4] -> 0x0100_0000
