Hi Marc Leeman!!!
Thanks for your reply for setting the u-boot environment variable
(boot_delay), but i have question for you.
Do i have to rewrite the u-boot on the flash after making the changes using
fw_setenv.
Is there any other work around without rewriting the u-boot to the flash.
Is it possible to just change the u-boot environment variable after booting
the kernel automatically??
Thanks in advance
Santosh

I still failed to bring up my ethernet on my custom PPC440GP board,
1. auto-negotiations timeout
2. wrong speed(10M), and wrong mode (half duplex)
Can anyone tell me how the drivers for PPC440GP RMII interface goes, thanks
a lot!
Below is my logs:
u-boot => tftp 0x100000 tmp.img
Trying ppc_4xx_eth0
the ZMII_FER = 0xe0000780
the ZMII_SSR = 0xe0000784
Waiting for PHY auto negotiation to complete..... TIMEOUT !
done
ENET Speed is 10 Mbps - HALF duplex connection
Using ppc_4xx_eth0 device
TFTP from server 192.168.65.235; our IP address is 192.168.65.239
Filename 'tmp.img'.
Load address: 0x100000
Loading: T T T T T T T
Thanks in advance!

Hello Jason,
you must have previously initialized RAM with another way to have an
writable area to set stack, data segment, BSS and so on (see remark in
Wolfgang Denk email).
If you have it, you can skip relocation by setting TEXT_BASE to a RAM
address and patch code in some files. What is your CPU ?
As for me, i have a board based on MPC7447/MPC7448 and i use this method
(not relocate code) to simplify debug with JTAG probe.
I have patch boot code in cpu/74xx_7xx/start.s file and relocation offset in
lib_ppc/board.c file :
/*
* Now that we have DRAM mapped and working, we can
* relocate the code and continue running from DRAM.
*
* Reserve memory at end of RAM for (top down in that order):
* - kernel log buffer
* - protected RAM
* - LCD framebuffer
* - monitor code
* - board info struct
*/
len = (ulong)&_end - CFG_MONITOR_BASE;
#ifdef DEBUG_JTAG_PROBE
/* IC-PATCH : Skip relocation to debug facilities */
addr = TEXT_BASE + len + (4096-1);
#else
#ifndef CONFIG_VERY_BIG_RAM
addr = CFG_SDRAM_BASE + gd->ram_size;
#else
/* only allow stack below 256M */
addr = CFG_SDRAM_BASE +
(gd->ram_size > 256 << 20) ? 256 << 20 : gd->ram_size;
#endif
#endif /* DEBUG_JTAG_PROBE */
Best regards,
Sebastien.

Use fw_setenv in the linux env to set the bootdelay to e.g. 10 secs then
you can change all you want in U-boot.
You could also use fw_setenv to modify all the u-boot settings you want,
provided you store them in flash.

PHY address 0 is on some PHY's a broadcast address. So possibly your PHY
will
respond to it's configured address and to address 0.
What is your PHY address? Meaning for what address is your PHY configured in
your design?

See above.

It seems to be a custom 4xx board. Did you enable the debug output of the
ethernet driver (INFO_4XX_ENET)?

Thsi is NOT what the OP wanted. He asked what needs to be done to run
out of FLASH only.

Hi all,
I am using u-boot 1.1.2 on my customized
board(440SPe Processor).I have xilinx System Ace
controller on my board to access 512mb compact flash.I
had formatted the
compact flash with FAT filesystem on windows pc.But
once the u-boot is up & when i try to access the
Compact flash through fatinfo it throws a error such
as
>fatinfo ace 0
** Partition 1 not valid on device 0 **
** Unable to use ace 0:1 for fatinfo **
My u-boot resides on on-board spansion flash(16 mb) &
i want linux kernel to reside in compact flash.Do i
need to set any environment variables to acces the
Compact flash or need add additional drivers for
xilinx system ace controller.please hep me in this.
with regards
raja
