Vxworks Program Exception Current Instruction Address
Program Exception current instruction address: 0x00000000 Machine Status Register. When vxWorks loads an application using the dynamic loading modules, it. VxWorks 6.x data storage exception Hello all, We are working on a designed-by-us board and an image project which is based on our BSP for our target. Smart Hlp 2 Rtf V3.0 Crack. The target processor is MPC8548 and we use Workbench 2.6 and vxWorks 6.4. The data access register contents are 0xa22dd5e4, is that a valid address for your board?

They are teling you that a task named 'tFtpServ1', whose task control block (TCB) is located at address 0x6533bc8, accessed memory at address 0x087f7564 while executing an instruction at address 0x000b0a00 and that access resulted in a data access exception. The remaining values are the contents of the indicated registers. These sort of errors are frequently the result of accessing memory that doesn't exist, often because of a programming error that results in use of an unitialized or otherwise erroneous pointer.

Hi, I'm facing system reboot often due to exception.
Following is the error msg. At boot up time. --------------------------------------------------------------------------- - Exception at interrupt level: Implementation Dependent Software Emulation Exception current instruction address: 0x000d0a68 Machine Status Register: 0x00009030 Condition Register: 0x44000040 Regs at 0xd0990 Press any key to stop auto-boot.
0 auto-booting.... --------------------------------------------------------------------------- From the above msg. It looks like 'something wrong' occured in one of the interrupt handlers and it rebooted and displays the exception information stored at exception address. Culprit is instruction at addr: 0x000d0a68 When i looked into symbol table of the VxWorks image (using 'lkup' in VxWorks shell), i couldn't find any function addresses close to '0x000d0a8'. In fact 'intrVecTable' (interrupt vector table) address was '0x000d0a50' which is in 'bss'. Egon Bondy Buddha Pdf. I could find all the global data structures close to this address.
