porting linux & u-boot on Mdp Pro 8xx board

[veikko romppainen]

Hi

I have currently running wxWorks on Mdp Pro 823 board. Now i'm trying port 
Linux on it. Firstable i have to get u-boot working on it. I hope someone 
has done this.

Is there working configuration from u-boot to this board?
I have modified QS823 conf, because it looks quite similar.

Can I use VisionIce 2 and SingleStep to flash u-boot?
We dont't have BDI in our school, shame. I flashed u-boot by using Ice 
starting at 0xfff00000. It seemed that it went correct place but nothing 
happened when i started my board.
I suppose that I can't  debug it with Ice and SingleStep.

Do i have to flash more than just u-boot.bin in right address? 
(Environment?)
Do i need  some reg files or prj files?

I would appreciate if someone could help me with these addresses and 
configs.

Board specs:
MPC 823 66 Mhz
4Mb flash
128 Mb RAM
512 K SRAM
8 K eeprom

Probably not. At least I don't know of any port of  U-boot  for  this
board.

BUT: this is off topic here. Please post U-Boot related questions  on
the U-Boot mailing list instead.

Similar is not good enough.

Probably, if you know how to use these tools. Sorry, I'm afraid  there
is little help for these on tyhe U-Boot list.

Is this the correct address for your board? Did you use  the  correct
terminal baudrate?

> I suppose that I can't  debug it with Ice and SingleStep.

You should be able to. If not, return the tools to the vendor and get
your money back.

No.

No. If  the  environment  is  invalid  (bad  CRC  checksum),  then  a
compiled-in default environment will be used.

> Do i need  some reg files or prj files?

Dunno.

Sorry, you need a lot more information about the hardware to give any
usable help - and then it requires a non-negligible amount of work to
come up with the right config data. Don't  expect  too  much  from  a
mailing list.
