PIC16F1939 bootloader assitance - Ido - 2024-09-04
Hello,
This is my first time using any bootloader so my experience is very limited.
I downloaded the ds30 loader free edition and tried building the project found at "firmware_12F_16F_XC8" folder using MPLAB X IDE v6.15
I am having trouble building the project even without making any changes(except putting a comment on "#error Do you need to configura uart pins to be digital? If not, remove this line")
When trying to build using the version mplab set(pack 1.2.63, xc8 v1.31) I get the following:
Code:
../src/user_code.inc:110:: error: (800) undefined symbol "EEADR"
../src/user_code.inc:132:: error: (800) undefined symbol "FSR"

build/default/debug/_ext/1360937237/ds30loader.o:70:: error: (501) program entry point is defined more than onceI am not really sure how to tackle the problem since I'm guessing this build has already been tested and works for other people and depending on the version I am using I keep getting different errors.
Any help will be appreciated!

Hello,
Please zip the complete MPLAB X IDE project and post it here and I will have a look.
RE: PIC16F1939 bootloader assitance - bryan45 - 2024-10-22
It seems like you're facing version conflicts between your toolsets, especially the DFP and XC8 versions. Try using an older XC8 version (like 1.45) that matches the DFP version others have used successfully. Also, make sure to remove all duplicate "_main" definitions and check the dependencies.
Sometimes these errors happen due to improper memory configuration within different MPLAB versions, so check linker settings too
