[ECOS] how to check my modifications to the kernel without a board?

[xiaolu zhao]

Hi, when I try the command: ecosconfig new pc_rltk8139 under the Cygwin
I got this complain:
  "fatal error - called with threadlist_ix -1"

Would you like to tell me what caused this problem and how I can solve it?

Thank you in advance!
