Problem with USB bootloader application and PE..

[yomioye2006]

Hi,

       I have attached a boot loader application  created without PE and an application created with PE.. I'm lost for what to do to make this boot loader work well with an application created with PE.. This boot loader has been verified to work well with a project created without PE. I've copied the linker file and applied it to the PE project but still won't work. I've attached all projects.  I did'not create the boot loader and no_PE applications so my knowledge of boot loaders is limited to what I read from the ANSI 3748 document.

1.  du_vfd.zip is the application created with processor expert

2.  no_pE is the application created without Processor expert. It works with bootloader

3.  SX01896-A00 is the bootloader application.   

Can someone with a lot more experience look at these an tell me what I'm not doing right or need to do? my processor is Coldfire V1 MCF51JM128  using code warrior 10.6 with PE. Thanks .

Original Attachment has been moved to: SX01896-A00.zip

Original Attachment has been moved to: no_pE.zip

Hi Yomi,

I only had short time to look at your issue.

I looked at the Xmap and s-record files for the PE and non-PE projects.

It looks to me that the PE based project does not have the vector table in the correct location.

Hopefully this will be helpful enough clue to resolve your issue.

Regards,

David

David,

        Thanks for looking at my issue. Can you please suggest a way for me to fix this? I tried moving the vectors to no avail using processor expert move vector to 0x00800000 ram address. It always end up generating a asm or mcf exception or in one instance my application runs once but on power cycle would not run again and I would have to power cycle to re program it.

Hi Yomi,

Please update your Vectors.c (i.e. @0x00000000 to 0x0000d000) as follows and see if this resolves your issue.

File attached too.

const tIsrFunc _InterruptVectorTable[111] @0x0000d000 = { /* Interrupt vector table */

  /* ISR name No. Address  Lvl Pri Name Description */

  (tIsrFunc)_SP_INIT,  /* 0x00 0x00000000 - - ivINITSP used by PE */

  _startup,  /* 0x01 0x00000004 - - ivINITPC used by PE */

Regards,

David

David,

         This moved the vectors from 0x00000000 to 0x0000d000 in flash and but the issues still persist. I'm still unable to flash my program using the bootloader and also my board fails to come alive if i turn off power and I'd have to power cycle to be able to re flash it with PE Micro MultiLink. What else does one have to do beside configuring vectors and properly setting the linker files to  use the mcf51jm128 bootloader application?

Hi Yomi,

The only other suggestion that comes to mind is making sure the vector table gets copied to SRAM and the VBR then points to that SRAM location.

Can you not use the debugger to see where the code crashes?

In the past I have set breakpoints in my bootloader and step through code to see flash erase, see the file is valid, see flash getting programmed, and finally seeing what values the code will use for PC and Stack Pointer before jumping to the new PC location.

Hi David,

     I used the below code to copy the vector table to the SRAM

void move_vect_table(void)

{

          int i;

   // PCP 13-011: Copy vector table to RAM 

   dword *pdst;

   dword *psrc;

   pdst=(dword*)0x00800000;

   psrc=(dword*)APP_FLASH;

   for (i=0;i<111;i++)

   {

  *pdst++ = *psrc++;

   }

   // Write new base address

   asm (move.l #0x00800000,d0);

   asm (movec d0,vbr);

}

APP_FLASH is defined

#if (defined __DEBUG__)

  #define APP_FLASH 0x00011000              //APP_FLASH 0x00011000

#else

  #define APP_FLASH 0x0000D000              //APP_FLASH 0x0000D000

#endif

Still can't get the Vbr to point to right location. Do you have any suggestions to get this application to flash correctly? Is there something in the startup code or initialization of PE that impedes proper flashing? I can't seem to locate anything and I'm not very good with debugging pointers at this stage. Thanks.
