ds30 works 1st time fails second time 18f6723 [abandoned] - Liamb - 2011-06-03

Hi all,

As the title says i have managed to get the bootloader to work but after i load anything for the first time I cant load anything else onto it. the pic im using is an 18F6723 and im using uart2 for the bootloader.
the following is my settings file

The following is the test file I have been trying to load with the bootloader

Code:
#include <18f6723.h>

#fuses none





void main()
{



int a = 1 , b = 0;
while(a)
{
b++;

}

 
   }


Another thing, I tried changing the oscf to 8000000 and the osc to hc but when i did this i got the following error from the bl gui

Quote:Initiating write...
  Searching for bl .
  Found PIC18F6723 fw ver. 3.0.0
  Waiting for bootloader to be ready...ok
  Writing flash ... unknown response 0x00, 1 try

  Write failed

Thanks in advance for your help

Hi,
Did you write configs? If you did, please try without doing that.

RE: ds30 works 1st time fails second time 18f6723 - Liamb - 2011-06-07

Hi Mikael,

there are configs set in the ds30 loader program as you can see from the settings file. the program i used to test the bootloader is a very simple program containing a basic loop, this was programmed using the ccs PCH compiler and has the line "Fuses none" in it that makes there be no config bits set and when i load the program into the bootloader gui it says the following.
Quote:Parsing hex-file ...
File timestamp: 03/06/2011 12:03:58
Validating hex-file...ok
Hex-file successfully parsed

20 program words found in 2 rows
0 Eeprom words found
0 config words found

so there shouldnt be any configs set. also I have been using the ds30 loader in basic mode so I believe there is no way to set it to write configs anyway. would it be better if i had the same configs set in the program i write as the bootloader and allow them to be overwritten?

Thanks for your help

Liam

After the first write. Do you reset the pic and press write within 2 seonds?
