[U-Boot-Users] mpc8xx Problem writing to flash

[raul.moreno at telvent.abengoa.com]

Hello people,

I am relatively a new U-Boot and Linux user.
First of all I have to port U-Boot to my custom board. I am using a MPC866.
The board starts as follows:

U-Boot 1.1.6 (Jul 23 2007 - 13:14:06)



CPU:   MPC866xxxZPnnA at 75 MHz [15.0...133.0 MHz]

       4 kB I-Cache 4 kB D-Cache FEC present

Board:     SM_CPU866 Telvent

DRAM:   4 MB

FLASH:  8 MB

*** Warning - bad CRC, using default environment



In:    serial

Out:   serial

Err:   serial

=>

I read the FAQ about this message in www.denx.de, but it seems not to be
OK, because after typing "saveenv", I got the following:

Saving Environment to Flash...

Un-Protected 1 sectors

Un-Protected 1 sectors

Erasing Flash...

 done

Erased 1 sectors

Writing to Flash... Timeout writing to Flash

Protected 1 sectors

Protected 1 sectors


The timeout out for the Flash is big enough (500 ms, although I also tried
with 1500 ms). I reused an "flash.c" code from a reference board of U-Boot,
which includes my same Flash chip  (Intel 28F160C3B).

Any idea how could I solve it?

Thanks in advance,

Raúl Moreno
