[indent]hello everybody!
I'm having problem with Coos RTOS with Mbed. Is there anybody who can tell me if i can redefine an exception handler that is previously defined in startup_LPC17xx.c?
I'm talking about PendSV_Handler(). How can i know how it is defined in Mbed? As we don't have the startup_LPC17xx.c file.
In fact i saw that it is originally defined as default handler i.e. an infinite loop. So maybe with Mbed, we couldn't redefine this handler (because it is already compiled: startup_LPC17xx.o already included) and that's why i'm blocked in my application while it makes a switch context. This is my assumption...
I guess we cannot redefine a function once it has already been compiled in an other file? Or the linker should give at least a warning message...But it doesn't...
Many thanks
Bye

I believe the default handlers are only weakly defined, so simply redefining PendSV_Handler() should be sufficient for the linker to favour your definition.
More information on this can be found on the MBed forum:
