bottloader with dspic30F4013 [solved] - d2inc - 2012-04-23
Good afternoon,
I am trying to incorporate a boot loader into a project. I have read through microchip's AN1094 and then I saw a link to this boot loader with the idea that changing the script file would not be necessary. So I thought this might be an easier way to get up and running. I have downloaded the code and have actually gotten things off the ground and running... I edited the settings file with my chip particulars, compiled the boot loader for the chip and programmed it into the chip. I have also got the graphic interface to recognize the boot loader and download my project code. This was all great and easy to use (thanks to people like you guys) but I ran into a problem that I can not figure out how to fix. The first load of the project file by way of the bootloader always works. But if I want to update the code after the first try, the boot loader is not recognized. I am sure I am probably "stepping" on the boot loader after it has initially done its job, but I am not understanding all the subtleties of the linker file, which is what I think is causing my problems. I have attached the edited setting file, and I am using the standard dspic30f4013.gld file. Could someone please point me in the right direction to be able to use the boot loader repeatedly for the same IC. Thanks in advance for your help.
I didn't see the attachment when I previewed the post so I am copying the text in here.

;------------------------------------------------------------------------------Well one step forward and one step back. I fixed the problem I had, not reset the chip before trying to download, embarrassing. But while trying to move on to my actual project (previous one was just a test to see if I could get it to go)., I have encountered the following problem...
Parsing hexfile...
File timestamp: 4/19/2012 3:57:49 PM
Opening hexfile...ok
Validating hexfile...ok
Unknown data found on line 485, 16 bytes at 0x1008
Unknown data found on line 486, 16 bytes at 0x1010
Unknown data found on line 487, 16 bytes at 0x1018
Unknown data found on line 488, 16 bytes at 0x1020
More unknown data...
Detected instructions where user goto should be moved to
The hex-file contains code that will overwrite the bootloader
Hex file successfully parsed
the "unknown data found" seems kind of scary, but does the other warning mean the code is to big to fit in with the boot loader?

Another gaffe on my part. It seems that somehow, the wrong chip was remember for the code I attempted originally. the default chip for the dsp30F (1010) got stuck in when I called up the program in the gui. I finally noticed that and the boot loader worked perfectly. Thanks you for your efforts in making this boot loader available to me.

Great! Thanks for reporting the solution.
