Hi Frank,

We are trying to port u-boot to Memec P4/7-FG456 as well. What did you
have to do to get the serial port working. Also did you get it to work
with uart lite that ships with EDK or the full uart that has to be
purchased separately.

Thanks,
Shamile

We used the full 16550 UART.  If you do, you have to keep in mind
that the UART registers start 0x1000 up from the UART's base address
as specified in your MHS file.  Also, you have to make sure you get
your register width right --  CFG_NS16550_REG_SIZE = 4.

-Frank.

to those of you who have ported uboot to the Virtex II PRO P4/7,
i have a nice, simple, straightforward question for you... :*)

what is your boot strategy?

do you load a minimal FPGA/uboot image (from flash) into the
internal RAM (~80KBytes big) and then in turn download the OS
and application code?
OR
do you have a very very simple FPGA/bootloader image which in
turn loads uboot into EXTERNAL RAM and then uboot loads the OS
and application code?
OR
yet some other way?

related to option 1 above...
does uboot for the the Virtex II PRO P4/7 fit nicely into the 80KB?

thanks for any insight.
