Watchdog for Boser (HS-7001)

Mon Dec 1 00:13:12 PST 2008

Hello,

I was trying the assembly language program that is specified in the following document (p24) to set, reset the built-in watchdog timer for the Boser Box.

http://www.boser.com.tw/manual/HS-7001v1.1.pdf

I then installed nasm in FreeBSD 6.2, and added the following lines at the beginning.

section .text
  global _start

  _start:

I did assemble, link (ld) and got no error. But when I run, I got the following error:

# ./watchdog.out
Bus error (core dumped)

I noticed that the port addresses used are similar with the following used by Super Micro Computer. I don't know if these are standards or not. I suspect that the boards are using same controller chips from Intel. I've been googling the web for more documentations on these but I could hardly find one.

How should I make this program works?

Thanks,

Won
