| Bootload CCS example |

Hi, I want use the this example bootlooader, but no compiler
| Code: | ///////////////////////////////////////////////////////////////////////////
//// EX_BOOTLOADER.C ////
//// ////
//// This program is an example stand alone bootloader. ////
//// ////
//// This program must be loaded into a target chip using a device ////
//// programmer. Afterwards this program may be used to load new ////
//// versions of the application program. ////
//// ////
//// This bootloader is designed to detect pin B5 low on reset. It ////
//// will then use the RS232 link to download a new program. ////
//// Otherwise the application program is started. ////
//// ////
//// Use an RS232 link and the SIOW.EXE or CCS_BOOTLOADER.exe program ////
//// to load a new HEX file into the target chip. ////
//// ////
//// Uncomment the define BOOTLOADER_MODE2X to use an alternate ////
//// bootloader that receives each line in the hex file twice and ////
//// compares them before acknowledging the line and writing it to ////
//// the target chip's memory. This mode only works with the ////
//// CCS_BOOTLOADER.exe program, add MODE2X to the command line to ////
//// use this mode. ////
//// ////
//// This example will work with the PCM and PCH compilers. The ////
//// following conditional compilation lines are used to include a ////
//// valid device for each compiler. Change the device, clock and ////
//// RS232 pins for your hardware if needed. ////

Error
*** Error 71 "main.c" Line 73(1,2): Out of ROM, A segment or the program is too large application
Seg 00500-00500, 0002 left, need 00004 Orged
What its the solution please?
I am new with the bootlooder, I want update the PIC across the net by one module TPC to TTL. So my idea is update firmware remotely |

Did you edit that file ? Or maybe you have an older compiler ?
You have the #org statement used with 16F PICs (PCM compiler),
but your PIC uses the PCH compiler. So you really need the statement
shown in bold below.
The current compiler has #if statements to automatically select the
correct #org statement. See below:
| Quote: | #if defined(__PCM__)
#org LOADER_END+1,LOADER_END+2
#elif defined(__PCH__)
#org LOADER_END+2,LOADER_END+4
#endif |
