[U-Boot] problem with loading new user script to memory

2011-02-18 Thread Toan Pham
Hi all,


I am starting to use Uboot for the first time and having a problem
with adding a new bootscr and loading it into memory.
I have a system with a sd-memory card, and add a new bootscr called
'myuser.scr' to the root directory.  I am 100% sure that the user
script is there in the root directory of the mmc; however, uboot can
not detect it.  When i boot to uboot promp and type in 'init mmc 1'
and 'fatls mmc :1'  it shows directory listing of all files under the
root directory, but it does not have the myuser.scr.  Question is, why
is myuser.scr not there?

[U-Boot] Full Arm emulator to run under x86

2010-12-09 Thread Toan Pham
Hi

I am new to uboot and I would like to learn it under an emulator
instead of a remote target.  For instance, I'd like to experiment it
with the Android operating system.  So far, I have tried qemu (utility
qemu-system-arm) to boot the kernel or an arm+uboot bootable sd flash
image on x86 architecture and the result was unsuccessful.  My purpose
is not to run for example Android on an x86 architecture, because i
know that there's Android for i386.  However, more of a full Arm
system emulator that should be able to boot U-boot bootloader and then
the Linux kernel, and also a bootable block device or image.


thank you,
