The CLR will freeze if compile the firmware with flavor = release or RTM, but it works fine if compile the firmware with flavor = debug.... Very strange issue...

Another issue is i used the none standard code && (Label Address) in the code, and build it with flavor other than debug, i'll get the errors and couldn't got the compile process done. But it can compile the firmware with no error or warning with flavor = debug.

Also, the firmware that compiled with GCC could not do the debugging in the MDK, it seems like there's some debugging informations missing... Please help, thanks!!!!
