Bootloader.c and SIOW.exe Problem

Hello,
we use the bootloader.c example.
If we download code to the 18F2520 with Siow.exe, it works fine until Siow reaches hex-code line 315.
Siow stops at line 315 with error message "timeout while downloading".
This error appears always at line 315 where address 0x1600 appears.
If we try to download an other code, it appears also at the line where address 0x1600 appears.
It seems that the bootloader can not process the line with address 0x1600.
Can one please advise me what to do?

First off, edit your post and remove that source code! It's against forum rules to post any CCS source code

Try using TeraTerm instead of SIOW, as I recommended to you in
this earlier thread:

It works now, CCS told me:

You need a new #USE RS232 after your "#ORG LOADER_ADDR+10, LOADER_END auto=0 default"
so that it uses a second copy of the RS232 functions in the default area and not the ones in the program area.
