[U-Boot-Users] AMD Flash not responding to Autoselect

[sudhakar rajashekhara]

Hi All,

I am using AMD 29F160 2MB on board flash on a custom
board. I am using the sbc8260/flash.c as the driver
file. During flash initialization, the flash is not
responding to the following Autoselect command
sequences.

/* Reset and Write auto select command: read
Manufacturer ID */
    addr[0] = 0xf0f0f0f0;
    addr[0x0555] = 0xAAAAAAAA;
    addr[0x02AA] = 0x55555555;
    addr[0x0555] = 0x90909090;
    udelay (1000);

    vendor = addr[0];
    printf("vendor = %08lx\n", vendor); 

After running these set of statements, if I display
vendor ID, I am getting the HRCW configured at the
base address of the flash. I am using 0xFE000000 as
the flash base. Any solutions?

thanks in advance,
regards,
Sudhakar.
