interrupt message information

epl — Mon, 22 Mar 2010 13:20:00 GMT

*** UNHANDLED INTERRUPT ***
Vector #: 11 0xb
Offset : 44 0x2c
Task Id: 0x10001 Td_ptr 0x2000529c Stack Frame: 0x2000652c
Interrupt_nesting level: 1 PC: 0x30000006 SR: 0x2600

what is the meaning of those parameters? This message is printed when calling _usb_device_recv_data() function.

Thanks in advanced!

Hi,

first of all, it is out of scope and useless now to decode the text with really high probability. You probable wrote something out of RAM (you dont handle RAM properly) or your stack overflew.

To be complete, I explain the text:

*** UNHANDLED INTERRUPT *** <--- unhandled interrupt occured (unhandled in the term MQX kernel does not handle it
Vector #: 11 0xb <--- vector of unhandled interrupt (probably something like zero dividing, illegal instruction etc.)
Offset : 44 0x2c <--- ISR vector table address
Task Id: 0x10001 Td_ptr 0x2000529c Stack Frame: 0x2000652c <--- information in which task's context it happened
Interrupt_nesting level: 1 PC: 0x30000006 SR: 0x2600 <--- if it happened in ISR context, then the information about ISR's nested, program counter and status register
