Howdy,
I have a board PPC405GP DHT-Walnut. It has
# two pci slots, keyed for 5V only cards
# Promise Technologies PDC20265 IDE
After attaching an IDE driver to the slot, uboot recognizes it:
IDE: Bus 0: OK
Device 0: Model: SanDisk SDCFJ-2048 Firm: HDX 4.03 Ser#: 003405D2697E4543
Haha. I solved the problem. The error is because I set the wrong
major/minor device id for /dev/hde.
Follow the result given by /proc/partition
major minor #blocks name
33 02000880 hde
I create nodes /dev/hde, /dev/hde1.2.3.4 by setting majorid=33.
This time:
# fdisk /dev/hde
hde:
Just now, I recompile kernel with even more IDE drivers. This time
it seems recognized my hard disk:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

Howdy,
I use uboot + linux kernel + ramdisk to start the board. The
kernel and ramdisk (say uImage and Ramdisk)
are stored on my PC. Each time, by typing:
tftp 20 uImage
tftp 60 Ramdisk
these two files are loaded to memory. Then enter bootm 20 60
to real boot. Well, I

Why?
Do you think on devices with
Howdy,
I know it is a newbie question. Any hint from you are welcome.
In default, u-boot 1.1.5, make walut_config make all will
generate a 256KB bin.
The last 4 bytes of the bin is a jump instruction to the entry point
of u-boot.Is that right?
But my ppc405GP walnut board has 512KB flash for

Howdy,
I want to compile ppcboot 1.1.6 by ELDK 4.1. Well, ppcboot is very
ancient code, but for some reason, I have to compile it.
There are many exact same compile-time errors reported:
error: lvalue required as increment/decrement operand.
xsum += *((ushort *)ptr)++;
*((ulong
Yep! The ppcboot is very ancient. hehe.
Actually, my board is DHT-walnut: http://elinux.org/DHT-Walnut_U_Boot
The web provides a pre-compiled bin uboot 1.1.4 for my board. The size is
256KB.
I downloaded it, and burn this bin into flash. But the board is still not
work.
Well, you point out a very

One day I tried to write some data into unused area of the flash:
