[ECOS] What I need to run "cyg_thread_delay" on redboot(motorola MBX)

[syyi04]

Hello, everyone.
Q : How can I run "cyg_thread_delay" on redboot? (Motorola MBX)

The following is what I've done to enable it on redboot.
  It works fine in the ECOS(ram version) but not on redboot(rom version).
  I add some packages to use the ECOS kernel on redboot.
    - eCos kernel
    - Dynamic memory allocation
    - ISO C and POSIX infrastructure, etc.....
 After cyg_scheduler_start, context switching works between threads
 which created by cyg_thread_create(...).
 But stuck in the cyg_thread_delay() function. It never ends.
 What should I initialize to use
 the clock and alarm related functions such as cyg_thread_delay()??
 I'm really wit's end.

Thanks in advance.... Good luck..
