Ttelmah, you're right : I'm trying to compile the loader with the project. I know it's not the "academic" way to deal with a bootloader, but my firmware is a serial loader and not a bootload ...

My bad !!!! Before calling the function, I obviously disable all interrupts, and I made several attempts with or without the WDT...

Actually, having the watchdog activated doesn't seem to have any ...

Good morning.

I just finished adapting CCS loader library (based on EdWaugh's code posted there : http://www.ccsinfo.com/forum/viewtopic.php?t=39179&highlight=firmware+update) for my own purpos ...

Hi !

I just got a new laptop, which had Windows 7 (64 bits) preinstalled. I installed my good "old" version of CCS Compiler on it (PCW 4.104) : no problem, wizard runned successfully. I o ...

Thanks for your advice : I guess I should have started by doing that. Downloaded both Programming Specifications : I'll read and compare them as soon as possible. Embarassed

Hello everyone !

I've been using a regular PIC18F4620 for quite some times now, and always used Tiny Bootloader to update the firmware on RS232. Now I'm switching to use PIC18F46K20, so my question ...

Ok, thanks for the info ! Seems I can't avoid upgrading, this time... Sad

Hi folks !

I've been away from the forum for quite some time, so first of all let me wish you all a very happy new year... Razz

Ok, now let's talk about my problem. I used to work on a PIC18 ...

Data sheet has nothing to do with it. The software UART, is a CCS function, _software_, not 'hardware' (which is what the data sheet covers....).
Ouups, I did it again... ! Embarassed

Seems I had a blon ...

Hi...

We are currently using an architecture based on a PIC18F4620, with hardware UART on pin C6/C7, and a software UART configured on pin C1/C2.

To add some new features to that prototype, we ...

The ctime() function does the conversion from a Unix Timestamp to a readable date and time. That function is the rtctimer.c file, which is included with the CCS compiler.
Nice !!! I didn't know ther ...

PCM programmer, I didn't get the .HEX for my bootloader from the net (not directly anyway) : the C source code was provided, and I had to change two lines to adapt it to my baudrate and my target devi ...

I think you're right, the problem seems to come from somewhere else ! I took an old project, kept all the includes and definitions, but changed its main() to use our test code... And it worked ! So I ...

Based on your piece of code, here is exactly what I used as a test code :
#include <18F4620.h>
#fuses HS,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=96 ...

Thanks for your answers...

Mr Guest, I believe printf() uses the first #rs232 defined in the code for its output, when you don't specify the output stream. Anyway, I tried removing the "stream ...
