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
