Can't you stop your uC at reset addr and step to see if you go to _start or
hit some exception?
I guess you connect GDB to JTAG via monitor and disassemble what you have
of ams instructions important here?
(I did not had time yet to recompile without this membar before
posting this question, so I will try to do it and reproduce the
problem).

how do we use itoa() fnc in U-Boot? I can seem to find it (there is

Hi all,
I have been looking at MAC addr obtaining procedure in lib_arm/board.c and I
am puzzled with this implementation :
/* MAC Address */
{
int i;
ulong reg;
char *s, *e;
char tmp[64];
i = getenv_r (ethaddr, tmp, sizeof (tmp));
s = (i 0) ?
Hmmm... what about these additional steps:
1) Add .o file to COBJS in ./common/Makefile
2) Add CFG_CMD_MY_COMMAND to CONFIG_COMMANDS macro in
./include/configs/board_name.h
3) Add CFG_CMD_MY_COMMAND definition to ./include/cmd_confdefs.h
are they necesarry? I think that I had to do these also.
section of u-boot that goes before TEXT section, and will never be
relocated to RAM _TEXT_BASE. What could that ever be?
Thanks for your answers.

Hi all,
I would like to eneble DCache in U-Boot, because peripheral register R/W and
SDRAM R/W is extremely slow on my platform, so booting Linux image takes
unexceptable long time. But apparently for ARM, MMU setup is needed first.
Now, I did not find example on any presented ARM platforms

Hi Wolfgang,
When something is wrong within TFTP, the respective function
returns an error code, which propagates upward and causes the running
command to terminate, so you automatically end up back in the U-Boot
shell.
Yes, I agree but the caller might do something else before exits
Hi Wolfgang,
Instead of vague descriptions like something is wrong within TFTP
or it breaks you could try and post the exact commands you're
trying and the exact error messages you are seing,
I am sorry for being vague, I hope this example will make it a bit more

I am having hard time to find exit() function in U-Boot, so I can exit from

Is there some alternative? I just want to break program execution, printf

Hi all,
can u-boot be copiled for PC (i.e. x86 machine) and run via qemu. I'd like
to use it for educational purposes, so I was wondering what would be the
best way to start it withouth the board.
