Hi, Jifl:
thanks, I'll try SID when I have time. in fact, emulate ARM
instructions on PC will only get 2-5 MIPS, what can we do in that too low
performance CPU, especially run multi-task.
but now I have changed into linux synthetic, modify linux_entry.c
and linux_intr.c in HAL, use linux memory image file to communicate between
eCos and peripheral equipment simulator application, and write a new I/O
driver, it works fine.
BTW, I have sent a mail which subject is *catch errors in eCos's
kernel* near Sep, 1. have you confirm it and checked it in CVS?
Best Regards,
james
