| Problem with Microchip HID bootloader and CCS CDC software |
 Posted: Thu Oct 08, 2009 2:06 pm |

Dear All,
I'm using Microchip HID bootloader (the latest Version) with PIC18F14K50.
When I'm using it with CDC demo from Microchip, it is working perfectly. When I'm using it with CCS (the latest version 4.099) compiler, it is working, but with problems. The same sample program based on CCS CDC example loaded to the chip without HID bootloader is working very well. I have indicated that problem is in the
| Code: | | if (usb_enumerated()) ... |
line. The usb_enumerated() never goes "1". However, I can not understand why the same program is working very well without boot loader. I have tested other CCS programs (not usb) and are working very good with the same boot loader. So, my question is :
Has anybody experience with this configuration CCS+PIC18F14K50+MC HID bootloader. Thank you very much for your help.
Please see here below exact listing of my CCS software, and header adopting it to HID bootloader.
My CDC software listing:
| Code: |
#include <18F14K50.h>
#use delay(clock=48M)
#include "C:\Users\MASTER\Desktop\CCS_CDC_HID\my_HID_USB_BOOTLOADER.h"
#include <usb_cdc.h>
#rom int 0xf00000={1,2,3,4}
#ZERO_RAM
#FUSES CPUDIV1 //System Clock by 1
#FUSES USBDIV1
#FUSES HS
#FUSES PLLEN
#FUSES NOFCMEN
#FUSES NOIESO
#FUSES NOPUT
#FUSES NOBROWNOUT
#FUSES BORV30
#FUSES NOWDT
#FUSES WDT32768
#FUSES NOMCLR
#FUSES NOHFOFST
#FUSES STVREN
#FUSES NOLVP
#FUSES NOXINST
#FUSES BBSIZ2K
#define MY_READ_EEPROM(x) read_eeprom(x)
#define MY_WRITE_EEPROM(x, y) write_eeprom(x, y)
void main(void)
{
BYTE i, j, address, value;
usb_init_cs();
do
{
usb_task();
if (usb_enumerated())
{
if (usb_cdc_kbhit())
{
i = toupper(usb_cdc_getc());
if (i == 'R')
{
printf(usb_cdc_putc, "\r\n\nEEPROM:\r\n"); // Display contents of the first 64
for(i=0; i<=3; ++i)
{
for(j=0; j<=15; ++j)
{
printf(usb_cdc_putc, "%2x ", MY_READ_EEPROM( i*16+j ) );
}
printf(usb_cdc_putc, "\n\r");
}
}
if (i == 'W')
{
printf(usb_cdc_putc, "\r\n\nLocation to change: ");
address = gethex_usb();
printf(usb_cdc_putc, "\r\nNew value: ");
value = gethex_usb();
MY_WRITE_EEPROM(address, value);
printf(usb_cdc_putc, "\r\n");
}
printf(usb_cdc_putc, "\r\nR)ead memory or W)rite Memory");
}
}
} while (TRUE);
}

My CDC bootloader adaptation header:
| Code: |
///////////////////////////////////////////////////////////////////////////
//// ////
//// MY_USB_BOOTLOADER.H ////
//// ////
///////////////////////////////////////////////////////////////////////////
#define LOADER_SIZE (0x0FFF)
#define LOADER_START (0)
#define LOADER_END (LOADER_SIZE)
#define APPLICATION_START (LOADER_SIZE+1)
#define APPLICATION_END (getenv("PROGRAM_MEMORY")-1)
#define APPLICATION_ISR (APPLICATION_START + 08)
#build(reset=APPLICATION_START, interrupt=APPLICATION_ISR)
#org 0,LOADER_END AUTO=0 void bootloader(void) {} |
Thank you in advance for help
Kind Regards |

You should check the initialisation performed in the C18 crt-startup files. Generally, the bootloader jumps to your application
after setting up several processor registers. It's not the default processor state as expected by the CCS code. |

| Another point, I forgot to mention. Are the fuses set in the HID-Bootloader or did you overwrite them when programming your application? Did you verify, that the settings are compatible? |

One thing to mention is that, try to add the following line to the beginning your hex file:
:020000040000FA
I had similar problem before.
Good Luck |

Hi,
I found your previous post about this extra line, and add it already.
Thank you |
