Hi , 

We are trying to port
Qnx on our custom board(based on i.Mx27). We have couple of issues while
porting : 
Following are those issues : 


1) The
custom board has Spansion 64 MB flash(S29WS512P), where as the i.Mx27ADS
has 32 MB flash S29WS256N 
We have built the redboot for our board.
We are able to download the Qnx image into RAM serially by load 
command. Qnx runs from RAM. 

Problem : When we tried to flash
the Qnx image using fis write command, redboot does not write into the
flash 
properly. It writes the first two bytes repeatedly for 16
bytes. 

Ex : Suppose Qnx image(in RAM) is having first bytes as
0C and C0. These two bytes are repeated for 
next 16 bytes in flash.
Again 17th and 18th bytes of RAM repeat in flash for next 16 bytes. 
The cycle repeats. 


2) FEC : 
i) We run the Qnx
from RAM (downloaded into RAM). 
ii) We are able to configure the ip
address (en0) for the board. 
iii) The localhost ping works properly.


Problem : When we ping the computer connected to the board
(FEC), 

i) PC does not respond. But we could see the ICMP
packets being sent in a network sniffer running on PC. 
ii) When we
ping the board from PC, the board does not respond. But ICMP packets are
sent by PC. 
iii) When we broadcast from PC, then the board responds.


Please throw some light on these problems and help us to
resolve the issues. 

Thanks, 
Krishna, Ravish
