[U-Boot-Users] RE: cfi flash problem

[Brad Kemp]

Shlomo,
Did you apply the patch that I sent out a few days ago?
It fixes a problem with x8/x16 size detection.

Subject: cfi flash problem


Hi, 

I am having a problem with cfi_flash.c on my board.

CPU: MPC850
FLASH :AMD L320DB * 4
Chip width: 8
Port Width: 32

Total flash size 16Mb.

It incorrectly reports the flash size as being 32Mb instead of 16Mb.
This 
is because it incorrectly identifies the port width as being 64 bit 
instead of 32 bit.

When I start U-BOOT and run fli I get the following:

Maybe the message "flash detect cfi" should be written in a debug()?
When I compile with the DEBUG option set I see the following:
