      Hello U-booters,
 Can someone shine some light on the TOC pointer's purpose and use in U-boot code?
Hit me with the clue stick, please =)

Hi all. I'm porting u-boot to a custom board with CPU S3C44B0X now.
I modified include/configs/B2.h accroding to my configurations.
And I don't know how to set the u-boot's console as serial port.
Thanks for your replies.

Subject: [U-Boot-Users] help starting
Hi,
I'm totally new to the world of porting U-Boot (or other boot loaders) 
to new hardware.
I have an older version of U-Boot (0.4.5) that was ported to 2 custom 
made boards we have, based on the MPC5200 CPU, and the IceCube 
evaluation board. Both has the same U-Boot up and running.
We now have a new board, base on the same design, but with some 
modification.
I have BDI2000 up and running, and I can access the board's memory, 
flash, cpu registers etc.
When I try to run the same U-boot, it, as can be expected, fails to run, 
and stop very soon after startup (no message comes out on the serial 
console).
I've tried to connect with GDB to debug, and I manage to do it, then 
step few commands, and I get SIGSTOP. To make sure that this is not a 
problem of the new board, I've tried the same with a working board, and 
the U-Boot fails at the same place (right after the starting point). On 
the other hand, if I don't try to do a step by step debugging, but give 
a "cont" command, the U-boot (on the older board) does work.
So I guess I have a basic problem in understanding how to debug the 
U-Boot with GDB.
Any help (either specific, or pointers to guides), will be great.
Thanks,
Ilan

Subject: [U-Boot-Users] Clarification regarding the Internal Flash Identification Code.
Hi All
   In the file "include/flash.h" some # defines are there e.g for
Intel StrataFlash 28F320J5 three Macros (hash define values) are there:
#define INTEL_MANUFACT	0x00890089	/*INTEL manuf. ID in D23..D16,
D7..D0 */
#define INTEL_ID_28F320J5   0x00140014	/* 32M = 128K x 32	*/
#define FLASH_28F320J5	0x0085   /* Intel 28F320J5 (  4M = 128K x 32 )	*/
Since I am using Intel StrataFlash 28F256J3, I have to define the three
required macros accordingly:
#define INTEL_MANUFACT	0x00890089	/*INTEL Manufacturer. ID */
#define INTEL_ID_28F256J3   0x001D001D /*Device ID*/
#define FLASH_28F256J3            /*Internal Flash Identification Code*/
I got the Device Id value from the Intel Site but I didn't found any thing
like Internal Flash Identification Code. Is this value is to be supplied by
the vendor if not then what value should I have to assign to the Macro
FLASH_28F256J3.

As the name "Internal FLASH identification codes" suggests this is  a
code  that  is _internal_ to U-Boot so you will not find it mentioned
in any vendor documentation (at least not before they are sterting to
manufacture "U-Boot flash chips" :-)
Just chose the next unused entry, but keep in mind that  odd  numbers
are used only for "bottom boot sector" types!

Hi,
Yes I've read it, but when I try this (on the older board, where the 
u-boot is working), the gdb doesn't stop at that function, just continue 
(and over the serial terminal, I see the normal u-boot messages, and 
later auto booting into linux).
Here is the screen dump of what I've done:

and I don't get the GDB prompt back unless I press CTRL+C.
Any idea?

Apparently not :(

Subject: [U-Boot-Users] crosstool for PowerPc 8540
Hi
 Could anyone suggest me the toolchain to be used to
compile u-boot-1.1.1 for a PowerPC 8540 board?
I tried with the crosstool-0.27 (www.kegel.com)
which is supposed to be the stable version ,and built
a toolchain with gcc-3.3.2 and glibc-2.3.2.
I could successfully build my toolchain and create
my u-boot binary for 8540.
But when I flash u-boot.bin , the board doesnt come
up.
Any help would be appreciated.
Thanks,
Junita
