Hi, Scott

I boot uClinux sucessfully by u-boot . Thank you again.

My steps:

1. Modify <u-boot>/include/configs/PK1C20.h to meet my custom board

2. make PK1C20_config

3. make

4. Start HyperTerminal with the following settings:

baudrate : 115200

parity : None

data bits : 8

stop bits : 1

flow cntl : None

5. nios2-download -g u-boot

I saw the command promt "==>". :-)

===================================================

TODO:

My custom board using Davicom's DM9000A(DM9000X serials). I'd like to using tftp by U-boot. So:

1. copy dm9000x.c dm9000x.h from original u-boot 1.3.1

2. modify some codes to remove some errors and meeting my custom board

3. make

4. nios2-download -g u-boot

5. in the terminal:

==> ping 218.192.171.46

dm9000 not found at 0x00200920 id: 0xffffffff

MAC: ff:ff:ff:ff:ff:ff

operating at unknown: 15 mode

transmission timeout

ping failed; host 218.192.171.46 is not alive

* Maybe IO routes doesn't work well.

* Another questions, I using MTD patitions over Flash. How can I access patitions in u-boot ? and How in uClinux?

* I need egrep in cygwin, but this version of cygwin dose not provide egrep. I copy egrep from redhat, but not worked. what's your suggestions?

regards,

Will
