I did try to search for answer in the forum but didn't see anything. I followed the steps in flascc sample 08 and Renaun's blog to debug my swc. Also, the same behavior even if I used the swc built from sample 08. The path for FLASCC_GDB_RUNTIME is correct and gdb is from sdk/usr/bin/gdb, I just couldn't think of anything else. Any help would be greatly appreciated. Thanks.
