[Playerstage-developers] problem while running player on ARM board

[prashant s. <pra...@ya...>]

hello to all of you, 
 this is my first mail to his group. I am quite new to player, and I am trying to run player on ARM board. I have ported player-2.0.3 with linux 2.4.19 on the arm board. i am trying to move pioneer with player ported on this board.
 when i tried with same version complied on my PC, it worked fine. 
 now when i run
  player pioneer.cfg
 along with 
 sonarobstacleavoid  in example/libplayerc++/ folder, it gives following errors. 
 1. on player console it gives:
 
 #player pioneer.cfg

 one thing i want to mention here. I have only one serial port available. so primarily i use this port to communicate with host PC through minicom, because the bootloader require certain inputs while booting up. once the board is boot up, i disconnect minicom, remove the serial cable and attach it to pioneer. in communicating with minicom and pioneer, /dev/ttyS0 is used. 
 
 kindly tell me where may be the problem. is it due to communication of both applications access /dev/ttyS0. if this is the case, then how should i proceed further.
 
 Kindly suggest me a solution . I'll be highly oblized and thankfull to all of you.
 
 with warm regards
