Hi,
Could you gave me further details on the version number, commands (menu
items) used when "open" the elf u-boot? I have tried with ADS 1.2, nothing
happened.
Thank you,
Regards,
Chris

Subject: [U-Boot-Users] U-Boot for CSB226
Hi,
I have CSB226 board having Intel Xscale PXA250 processor on it. The board
already has got micromonitor on it. I want to put U-Boot-1.1.1 in it.
I have a few queries.
1. I want to put U-Boot-1.1.1 on CSB226 board in RAM and use it as a boot
loader for Linux. I do not want to erase the original micromonitor code in
Flash, so I need to put the U-Boot in RAM using TFTP of micromonitor. What
changes should I make to the configration file of CSB226 to make this
possible. 2. Where in RAM should I load the U-Boot. I have already got
initrd.bin that has to be loaded in 0xa0800000and zImage that has to be
loaded in 0xa0108000. 3. What will be steps to build the U-Boot image, in
order to achieve the above setup.
Thanks and regards,
ORP

U-Boot uses GCC-specific features so if your compiler is not GCC you
probably can't use it for U-Boot. If you insist on working in Windows, your
best bet is using Cygwin.

Just open the ELF file (u-boot) in CodeWarrior. CodeWarrior will build the
project (with many warnings, though). For flash burning and simple debugging
it should be enough. You have to read CodeWarrior documentation to
understand how to fix the project for your needs.

Subject: [U-Boot-Users] UART Initialization Problem (ns16550 on arm920t)
Hi,
I am porting u-boot 1.1.1 on a new board. The board is arm920t based and
it's UART port is compatible with ns16550.c so I changed the serial driver
(serial.c) on the cpu/arm920t directory with the serial driver + ns16650
module available in the drivers directory. I am using bdi2k for debugging
and I have initialized the UART port on the bdi2k config. The problem is
that when the initialization routine in armboot_start calls serial_init of
the ns16550, there are no messages, i.e. no prompt, on my serial console.
When I remove the serial_init on the list of initialization functions of
armboot_start, a prompt appears. I can successfully type help, and do other
stuff. Whenever I try to remove the initialization routine on my BDI2k
configuration and put back the serial_init function on the initialization
list, I am not getting any messages on my serial console.
What could be the cause of this problem? The initialization routine on the
bdi2k and serial_init are almost the same (i tried to make the sequence and
the values exactly the same but I get the same result) but there are no
messages displayed on my console. =(
Thank you very much for your help.
Best Regards,
Rodel Miguel

The FAQ tries to answer FAQ's, obviously, and thus must be a bit generic.

First, this may work fior you, but it will not work for me. It does not
work on PowerPC, and it does not work on MIPS for example. And it does not
work if you have configured your BDI200 as recommended, i. e. that it works
with a mostly virgin CPU.

Yes, This is one of the many things you can do if you know what you are
doing. If you don't have a clue it will just cause more problems and
questions.

Subject: [U-Boot-Users] sdram byte ordinary erron after relocation
Hello everyone,
I am porting U-Boot to my ppc850 board, and my program crashes after
relocation to ram. I used an SDRAM driver which works normally in VxWorks.
But when I call the
relocate_code() funtion, there is an error of byte ordinary. If I write a
number to memory, the higher 16 bits exchange position with lower 16 bits.
For an example, if I write 0x2705,1956 to sdram, then I get 0x1956,2705 when
I read the memory address. But I can read or write flash correctly.
I read chapter 13.2.3 of the guild file. There is an argument related to my
problem.
>Argument:
>But my board ran fine with bootloader XYZ and/or operating system ABC.
>Answer:
>Double-check your configuration that you claim runs properly...
>Are you sure the SDRAM is initialized using the same init sequence and
values?

doesn't, it isn't a valid comparison.
I checked these issues, and I am sure that the init sequence and memory
controlling registers are as same as the VxWorks'. But also, BDI2000 can
read or write memory exactly with same init sequence. The only difference is
my VxWorks system didn't use DMA function.
At first, I am doubltful of wrong endian mode. Then I checked correlated
register. MSR register is 0x1002 and DC_CST register is 0. I think it should
be right. This problem puzzled me so much, and any clue given to me will be
apreciated!
Best regards,
Kenny Lew

Subject: [U-Boot-Users] get_timer documentation
We use coldfire 5282
We need to know what is the parameter and return value of get_timer()
we wnat to use get_timer() to calculate time intervals in millisecond.
something like:
....
a = get_timer(0);
/* do something */
b = get_timer(0);
....
in this case what is the measure unit of b-a?
How can I obtain millisicends?
thanks

Maybe having a short look in the source code brings some ideas?

Yea, that's what it's intended for.

milliseconds.
And why not simply:
a = get_timer(0);
/* do something */
millisecs = get_timer(a);
???
> How can I obtain millisicends?
I don't know. What's a sicend?
