Could you help me to properly associate samples array to a memory bank ?
The problem persists when I have bootloader+application and fft.h library just included without using any of its functions.
...

Here the main steps related to fft computation.

#define FFT_LENGTH 512
#define SAMPLE_SIZE 2048
#include <Lib/fft.h>

typedef struct _complex

I verified with LED debugging that isr is executed at correct timing.
It seems a memory boundary issue related to contemporary use of bootloader and FFT library:
#include <Lib/fft.h>

If I a ...

Thank you!

I wrote to technical support, I hope they'll help me to get rid of this weird issue.
Meanwhile could you share me links to threads related to similar problem with bootloader ? I would l ...

I used:

#include <33EP512GP502.h>
#OPT 0
#define LOADER_PAGES 8
#include <pcd_bootloader.h>
#include <dsp_data_util.c>

also with even (8) loader_pages both in bootloade ...

I also monitored isr execution time in application standalone code.
It is ok, isr needs few microseconds less than period required to reach Fsampling.

I don' t think It could be a Memory issue...
Bootloader occupies 1% Rom program Memory and 9% RAM in worst case.
Application occupies 2% Rom program Memory and 46% RAM in worst case.

Please help ...

Hi,
I used #OPT 0 in both bootloader and bootload application.
I removed clear interrupt from isr code and replaced the first switch with if else statement.

#include <33EP512GP502.h>
#OP ...

Thank you Ttelmah,
I'll try #OPT 0 ASAP.

Meanwhile some clarifications:
- Fuses match between bootloader and application (No change)
- No other interrupt required or used

I looked AIVT bootlo ...

Hi,

Thanks !!

Now it's working with Receive_buffer only in application.

Regards!

OK.
I removed receive_buffer from bootloader part.

Can I keep it in application part ? Or could it be a problem ?

When I load the application without bootloader part it works fine...

Please, give me example in order to use #build and expand stack...
Do I need it only in application or also bootloader code ?

In application I have:

#use delay(internal=20MHz,clock_out&# ...
