PIC18F26K22 troubles - doubleeaz - 2013-08-31
This is only the second time that I have used the ds30 loader bootloader and running into some issues.
I am using a PIC18F26K22. Using UART1. I have compensated for the BRG issue in the errata (must set BRG16 and BRGH). I have made sure all ports are correct for analog & digital (ANSELx registers).
I am running 16MHz, 19200 baud (also tried 9600). I can run check for bl and it gets recognized. version 3.0.2.
When I try to write, i get the following.
Initiating write...
Searching for bl .
Found PIC18F26K22 fw ver. 3.0.2
Waiting for the boot loader to be ready...ok
Parsing hexfile...
File timestamp: 8/25/2013 6:51:46 PM
Opening hexfile...ok
Validating hexfile...ok
Hex file successfully parsed
Writing flash....response timed out
Write flash failed
Tx 7 bytes / Rx 4 bytes / 15.5s
Write failed
I probed the pins of the PIC and see traffic. Files are zipped and attached. Any help would be greatly appreciated.

Hi,
Sorry for the late reply. I've been on vacation.
Do you use RS232 or RS485? If RS232, comment this line
Code:
#define USE_TXENABLE 1RE: PIC18F26K22 troubles - doubleeaz - 2013-09-12
Thanks Mikael,
I am using RS485. I found some files for a PIC18F25K22 that I modified and it seems to be working. About the only change was to go in and configure comparators and all TRIS registers.
Regards,
Rodger
