CCS 5.104
Hello,
I have a working bootloader code for PIC24FJ48GA002 and now i am trying to test it on a PIC24FJ128GL305 but I get "Error#126 Invalid ORG range:"
| Code: |

If I change to :
It works, I do not know if this will cause any problem
but the bootloader compiled and I got it to download the firmware successfully.

OK, without setting the org range, the timer interrupt is not working.
I guess it is related to this:
| Code: |
#int_default
void isr(void){
jump_to_isr(LOADER_END+5);
}
|
So what is the correct org range?

That is the wrong #org for the application. It needs to just use
| Code: |
#org APPLICATION_START
void application(void)
{
while(TRUE);
}
|
Your current #ORG making it clash with the #INT #ORG....
You are trying to load the application into the vector above the LOADER,
where the jump to the actual application needs to be. This then makes
it clash with the interrupt re-vectoring table (on PCD, the #INT_DEFAULT
jump_to_isr code generates a whole new vector table for the main
application). Hence it can't get it to fit.... |

Ttelmah to the rescue once again.
The code from the example is working just fine.
And it also worked for the PIC24FJ128GL305 but the interrupt never triggered.
I will try your suggestion and report back.
Should I also change this to past projects already working?

Are you sure you need the stack to be 1K?. That is using a lot of your RAM.
Look at the stack size in the compiled code. Remember each 'location' needs
two bytes, but I'd have thought something like 512, would be enough.
Your fuses need NOIOL1WAY, or your main code is not going to be able
to set the PPS for devices. Possibly this is what is preventing the interrupt
from working (the device is not actually on the pins you think).
What interrupt are you trying to use? Obviously check it is enabled etc..
Have a great Christmas.  |

Hi!
I changed to #org APPLICATION_START but the timer2 interrupt does not fire. Everything works, OLED,UART,SPI but not the interrupt. Maybe the "jump_to_isr(LOADER_END+5);" is wrong? why +5?
The interrupt and the timer are configured correctly because if I run the firmware directly without bootloader the interrupt fires.
Please look at the code below.

I found it.
I had the "#INT_TIMER2" both in the bootloader and in the firmware 
I removed it from the bootloader and now it works in the firmware.
As about the stack size, no I am not sure it should be 1K. I remember that this is usual for PIC24 and DSpic.
Where can I see the stack size in the compiled code?
Thanks!!!

You open the .lst file generated. About 10 lines down it has the number of
stack levels used.
Normally the default stack, is just a little too small if you are using
complex printf statements. However 1024, would only be used if you
had a rather extreme number of calls inside calls inside calls.
For example my current code in a PIC33EP512GM305, is over 195K bytes
in size, but only uses 204 stack levels. 512Bytes works fine.
Remember the stack uses 2 bytes per level, and having perhaps a 10%
margin in sensible.
1K is not 'usual'. But having to expand it beyond the default size is.
1K is commonly used on some of the chips with more RAM than yours,
but it is worth being a little more 'stingy' if you start to find RAM running
short on the main program.
Yes, using interrupts in the bootloader is difficult. Better to 'poll' the
interrupt bit involved, which simplifies things massively. You can do it by
having separate vector tables for the main and the bootloader.
Glad you are moving forwards.
Happy New Year to all. |

| Code: |
ROM used: 5890 bytes (7%)
Largest free fragment is 53502
RAM used: 1593 (19%) at main() level
1627 (20%) worst case
Stack used: 64 locations (26 in main + 38 for interrupts)
Stack size: 512
|
64 locations. so, 64x2=128?

Exactly. That would just be hitting the limit of the default stack. Worth
going a little bigger, but not to 1K!... |
