" ihex too large for flash"

[shyhkaelo]

I built a project and compiled it, the program used 520 bytes showed in MPLAB X IDE
But when I executed pyupdi to download my code, terminal replied the information " ihex too large for flash "

Can you add here this ihex?

I wonder if its because MPLAB bakes the fuse values into the hexfile at a high offset...?

A year later...did anyone find a reason for this or a fix? I have the same issue. MPLAB IDE tells me I'm using a few % and then pyupdi says its too big.
I am using a mega808. I have successfully programmed using a simple blinky code.
Then I started using Microchip code configurator but now it is "too big".
I attached my hex (as txt) if that helps.

Same thought - MPLAB is putting fuses in the hexfile at a huge offset, and pyupdi is not fuse-aware.
I recommend to use pymcuprog which is properly maintained
Give it a try at least: pip install pymcuprog

Hey thanks for the reply. I'll check it out. I am trying to simply program with it but I have no luck. Is this correct?
pymcuprog write -d mega808 -t UART -u COM10 -f myfile.hex

I get the answer:
Connecting to any UART pyedbglib.hidtransport.hidtransportbase - ERROR - No CMSIS-DAP devices found. Unable to connect to USB device

For anyone else facing the problem of not reading the documentation well, I did this and it worked
pymcuprog ping -d atmega808 -t uart -u com10

ah, case sensitive...
