Hi,

 Is it possible to load movie on swf application from a callback method

 which is invoked by a native c application? I could load a movie using

  loadMovie(xx.swf , this) function outside callback method but not via invoking callback method.Please reply ur suggestions.

Thanks,

Princy  

Hi ,

Dear Everyone.

I’m trying to port QNX into my own SoC platform.

My own SoC platform is based ARM926EJ-S 32-bit RISC Core which operates 141MHz and has 32MB SDRAM(base: 0x10000000) and 1MB NOR Flash.

The tool is QNX Momentics 6.3.2 non-commercial version.

I was modifying IPL, startup, and serial device driver of the legacy Samsung S3C2410 BSP which had developed by RT Solution ago.

I met the shutdown message with SIGBUS.

Thus, I debugged my BSP by TRACE32 ARM In-Circuit Debugger.

Attached 2-1.PNG image file is my debugging information.

In pa_quantum_to_paddr, during “ldr r3,[r3,+r1, lsl #0x2]” execution at the address 0xFE01CB08,

when r1 was 0x2, operation was good but when r1 was 0xFFDF, exception happened.

Because r3 had abnormal address at that time, memory access violation happened.

Pa_quantum_to_paddr is the function of the kernel and thus I have problems to debug it.

What source code out of the startup source code or serial device driver source code causes this problem ?

After meeting shutdown message, I saw where PC is located.

You can look at this at the attached file “trace32.0219.PNG”.

In addition, You can see QNX’s procnto is loaded and running.

Best regards.

Hello.

My 32-bit ARM9 RISC SoC has just 1 interrupt controller with 29 interrupt sources.

If I understood the cascaded vector’s meaning well, I doesn’t need cascaded vectors.

Is it right ?

const static struct startup_intrinfo intrs[] = {

           {          _NTO_INTR_CLASS_EXTERNAL,                 // vector base

                     32,                                                  // number of vectors

                     _NTO_INTR_SPARE,                              // cascade vector

                     0,                                                   // CPU vector base

                     0,                                                   // CPU vector stride

                     0,                                                   // flags

                     { INTR_GENFLAG_LOAD_SYSPAGE,  0, &interrupt_id_jaguar2  },

                     { INTR_GENFLAG_LOAD_SYSPAGE | INTR_GENFLAG_LOAD_INTRMASK, 0, &interrupt_eoi_jaguar2 },

                     &interrupt_mask_jaguar2,           // mask   callout

                     &interrupt_unmask_jaguar2,        // unmask callout

                     0,                                         // config callout

           }

The upper source code is my startup_intrinfo but I think its source code has the problem.

I think that there is some proper value for a cascade vector instead of _NTO_INTR_SPACE. 

Actually, I didn’t understand the meaning of the cascade vector.

Please help me.

Best regards.

Pusik.

Dear Everyone.

I’m debugging my BSP by TRACE32.

I built bsp-xxxxx.ifs and procnto-instr.sym.

I loaded bsp-xxxxx.ifs by TRACE32’s Data.Load.Binary command at the SDRAM memory region (0x10800000), which I set up as the System Build/Property/General/System/Image Address.

At TRACE32,

I performed like the below

Data.LOAD.Binary C:\QNX632\ide4-workspace\bsp-jaguar\Images\bsp-jaguar.ifs A:0x10800000 //verify

if data.long(&DNLD_ADDR)!=0x00ff7eeb

 (

             print "Wrong QNX image magic!"

            stop

          )

Register.Set PC data.long(&DNLD_ADDR+0x0c)   ; startuphdr.startup_vaddr

Data.Load.Elf C:\QNX632\ide4-workspace\bsp-jaguar\Images\startup-jaguar2eval.sym /nocode

Data.Load.Elf C:\QNX632\ide4-workspace\bsp-jaguar\Images\procnto-instr.sym /nocode /noclear

I go my QNX and stop at any point.

I could check the startup-xxxxx2eval’s symbols by TRACE32’s symbol.browser.

I could look at Symbols, Variables, Functions, and Modules by symbol.browser.

However, I could NOT look at the procnto-instr’s all symbols.  

I could see Global symbols and Global variables(os_version_string and timestamp), but could NOT see any Global Functions.

How can I obtain the procnto or procnto-instr with whole Function symbols ?

My BSP went to “__hardcrash”.

I looked at the below data at the window of TRACE32’s Var.Frame.

           SR:0xFFFF:0xFC4046D8(asm)

           scrn_display(asm)

           kprintf(asm)

           shutdown(asm)

           kdebug_enter(asm)

           arm_undef(asm)

           __und_entry(asm)

--->   exception

           SR:0xFFFF:0xFC404174(asm)

This looks like the call stack.

What’s the problem ?

Please give a comment.
