Flash_Erase with Timer Interrupt problem

[lololafripouille]

Hello,

I use a dsPIC33EP512MC806 with VTFT v461 and MikroC dsPIC 701.
I use internal Flash to store an array of 16 byte.

All is working great, I store values in array and after a reset, read and print values on TFT.
But If I add a Timer interrupt ( Timer 2 triggers every 25ms ), calling the function Flash_Erase reset my MCU and Timer 2 interrupt no longer works.

There is nothing in the interrupt function, just a flag incremented and then resetted in the main - while(1) function.

I can't publish my code right now, i'm sorry.

Do you have any idea ?
Thank you for your help

Hello again.

I managed to solve my problem.
Maybe it can be usefull.

Instead of

Code: Select all

void Timer6Interrupt() iv IVT_ADDR_T6INTERRUPT ics ICS_AUTO

I used

Code: Select all

void Timer6Interrupt() org 0x4A000 iv IVT_ADDR_T6INTERRUPT ics ICS_AUTO

0x4A000 was empty and far from the address Flash I use and far from the memory usage of my program.

Is it possible to have an explanation from a C master/guru why it was not working without the org directive ?
It will be nice if I could understand why

Thank you

Hello,

I made again some change in VTFT and now, calling the function Flash_Erase reset my MCU....again.

If I delete the org directive in Time6Interrupt, it works !

I don't understand why. If I can have some info from MikroE team it will be great.
I don't understand the memory alignment, maybe it is a problem of the Address I choose to write on Flash.
I choose a multiple of 0x800 ( 0x51000 )

Thank you for your time.

Hi,
have anyone found a solution fo this problem. I have same problem with dsPIC33ep512MU810.

I would be grateful if you share a solution.

Thank you
