Forum Index : Microcontroller and PC projects : Olimex PIC32-T795 Linker script

I am new to using PIC32 although have used 8bit pics a little in the past. I recently purhached a maximite and then decided to try my hand at using C instead of basic and purchased the "Olimex-T795". Can anyone help with which linker script I should use in MPLAB? I am scared that the incorrect linker script will wipe the bootloader ? |

When I asked about this some time ago Peter, this was Tsvetan's response: Wish to program the DuinoMite in C?
Olimex Pinguino IDE supports the DuinoMite even now. No need for a special linker script as there is one for the 795 already. Use the existing bootloader that is programmed into the board. Tsvetan of Olimex. Cheers Don... https://www.dontronics.com |

Hi Don. I am still a little confused I know the MPLAB IDE has a generic linker script for the 795, is this the script Tsvetan is talking about,or is he talking about another linker script supplied with Pinguino IDE |

@eisley, the linker script is your concern only - don't get stuck on that. Look at the keywords of Don. He said: I want to program the board in C. The answer: Use Pinguino IDE with the existing bootloader on board. Don't worry about linker script! Pinguino IDE is working as Arduino IDE. Just write the program and hit upload button. _________ Of course, reading the docs is a good habit (explore the Pinguino IDE package, search on Pinguino forums, etc.).

I have just downloaded Pinguino and tried to upload a program to the Olimex PIC32-T795 but Pinguino doesn't reconise the bootloader.. I have writen a small c program to flash leds using Microchip Mplab and the maximite.ld linker script, this program loaded ok with Olimex bootloader and run fine. However when I try to write more complicated programs using interupts etc I get errors from the linker script.. Can I use the generic linker script ? |

The last version of Pinguino is in SVN. Tried to access the site at http://pinguino.cc but it says "Access denied." . I will try again later, to actualize my data - not using Pinguino currently (I'm involved right now with some ATmega's and gcc).

elsley - Have you tried reading / asking on the Pinguino forum? The people who understand its usage of ld scripts are there. John |

Just an update - i received a comp of the correct linker script from the technical guys @ Olimex. Tried it in Mplab and still got many errors... I eventualy found using and older version of the c compiler fixed my problem.. I was using the new Microchip XC complier toolsuite.. |

let me know how it works out Peter, and I'll add any additional info to my pages to assist others. Cheers Don... https://www.dontronics.com |

I think Microchip have changed various things (such as region aka section names). Helps get smaller and more appropriate code, probably. John |
