[Skyeye-developer] polling the UART [resend]

[Rommel Custodio]

I am actually making the firmware for the Surveyor SRV-1 run under Skyeye.
The source code is available from Surveyor's website:
http://www.surveyor.com/srvdownload/srv-041507.zip

This code builds and runs fine on an actual SRV-1 robot, but as I mentioned
it doesn't work under Skyeye. The PLL check goes into an infinite loop so as
the code fragment I showed below.

Here is my skyeye.conf file:
$ cat skyeye.conf
#-------------------------------------------------------------------------------
cpu: arm7tdmi
#-------------------------------------------------------------------------------
mach: lpc
#-------------------------------------------------------------------------------
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00020000
mem_bank: map=M, type=RW, addr=0x40000200, size=0x0000fe00
#-------------------------------------------------------------------------------
uart: fd_in=/dev/ttyS4, fd_out=/dev/ttyS4
#-------------------------------------------------------------------------------
log: logon=0, logfile=/tmp/sk1.log, start=100000, end=200000
#-----------------------------------------------------------------
lcd: state=off

I guess arm-elf-gdb is not support lpc simulation.

FWIW, I am using the arm-elf-gdb from gnuarm.org.

Any help will be highly appreciated.
