DRA722: vision sdk debug on ccs

rangzhou liu

Part Number: DRA722

I am try vision sdk on dra722 , after load IPU2_C0 program from CCS , I using step debug , when I step over

    gSystem_objCommon.tsk = BspOsal_taskCreate(
                                (BspOsal_TaskFuncPtr)System_main,
                                "System main",
                                (Int32)SYSTEM_TSK_PRI,
                                gSystem_tskStack,
                                sizeof(gSystem_tskStack),
                                NULL,
                                UTILS_TSK_AFFINITY_CORE0);

processor never stop, I click suspend , PC pointer is :

UInt32 Timer_getCount(Timer_Object *obj)
{
    UInt32 tcrr = ((TimerRegs *)Timer_module->device[obj->id].baseAddr)->tcrr;

then I click Step Into , The Warning :

Cortex_M4_IPU2_C0: Can't Run Target CPU: (Error -1268 @ 0x1090001) Device is locked up in Hard Fault or in NMI. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.4.0.00006)

Why?

And If I using Restart to run again , Registry_addModule(&Registry_CURDESC, MODULE_NAME); return Registry_addModule(&Registry_CURDESC, MODULE_NAME); There is no global variable clear ? In generally , .bss need to clear at program start ( before main function )

You can't restart program. The system has to be reinitialized so you have to reboot the board and reconnect again.

As for stepping over functions in CCS, there are few possibilities.

- Debug build vs Release build

With release build, the optimization is on so when stepping over, the control can go back to OS scheduler so you don't see the program start.

- Interrupt

There could be interrupt coming in so the system goes to some other function.

- Crash

There could be issue in the code and system crash after stepping over.

My suggestion is to set Breakpoints and run, instead of stepping, to see if the program reaches to specific function or line of code. In addition, use Debug build if you want to step thru the code.

I am using Debug build and commented out the initiallization code in GEL file.

Why can't restart program ? It is means that the program not initiallized all variable at startup ?

I am using XDS100V3 debugger , connect and load program take a long time, more than 30s , how to improve it?

Restart program option in CCS just set PC back to entry point and run again. It doesn't reinitialize the system so you can see some random behavior or crash.

XDS100v3 is a low cost debugger so its speed is limited.

You can get XDS200 or XDS560v2 debugger for much faster speed.

In my opinion, vision sdk user program need to initialize the system.

System is initialized by boot loader (SBL) first and then it loads vision sdk application image.

When loading the vision sdk application image in CCS, CCS GEL script will initialize the system when connecting. This is the equivalent steps as SBL. When restart iin CCS, it only goes back to the beginning of application image.

Please go over Vision SDK documentation for more details.
