| dsPIC30F6014A PCD Bootloader OK and App FW with No Interrupt |
 Posted: Thu Nov 14, 2019 1:52 am |
 |

I uploaded the boot loader FW and downloaded a simple application as shown below.
The result is that the normal functioning works fine, but the timer and RS232 receive interrupts do not.
Why not do interrupts?
Thank you for your help.
Please note that the bootloader code could not be attached due to many modifications.

The fault is almost certainly that your bootloader is not correctly re-vectoring
the interrupt handling. So it is the bootloader you need to post.... |

Below is the bootloader code.
The boot loader is very complicated.
However, the download is normal and the default operation is not abnormal except for interrupt.
Please treat me well.
Thank you.
Ttelmah! thank you.
Three bootloaders / application firmware / final firmware hex files were compared.
Vertor has detected a problem with the bootloader 0x0 address and the application firmware 0x0980 address.
PCB_Bootloader did not fix it.
Where is the problem?

Interrupts were resolved by changing the order in the source phase.
Thank you. |
