[microblaze-uclinux] Memec S3-1500 board + P160 comms 2

[John Williams <jwilliams@xxxxxxxxxxxxxx>]

Hi,

Has anyone tried connecting the P160 Comms2 module to the Memec S3-1500 
board?  Using the XBD/BSB tools, it assumes the module is on P160 Slot A 
(left hand side of the board).

However, when placed in this slot, the P160 MAC phy_rx_d<3> pin, defined 
as 3.3V LVCMOS, connects to FPGA pin AD13, which is on the same IO bank 
as most of the main board's DDR signals which are 2.5V SSTL.  e.g.:

fpga_0_DDR_SDRAM_16M IO  SSTL2_I        1.25   2.50   PAD327 AC13 
  fpga_0_P160_Ethernet I   LVCMOS33       NR     3.30   PAD326 AD13

PAR refuses to continue, and rightly so.

I'm redoing my project to try the module in the other slot, hopefully 
that will not have this conflict.

If anyone from Insight/Memec is listening, please let your engineering 
teams know - or is there an erratum already available for this combo?

Cheers,

John
