Hi
I have a trouble as well.
I have just compiled this ex_bootloader from 5.013 for 16F1827, and it compiled okay and seems working for triggering by PB and serial port communication.
Then I downloaded a small test program, this ex_bootloader writes only part of progarm.
My application should be from 0x300 to 0x349 but it writes only
0x318 - 0x31F
0x338 - 0x33F

It seems this bl erases 32 words, but writes only last 8 words.

I used SIO.exe.

This is a different problem.
It's a chip database error on the configuration of the flash memory. Several chips seem to have problems like this recently... :(
They have the setting set as 64/64 (which means it erases 64 bytes at a time, and writes 64 bytes at a time). In fact the chip needs 16/64.
If you have the IDE, you can change this through the device editor. If not, report it to CCS (do this anyway), and ask them to give you an updated .dat file. They should be able to do this very quickly.

SOLVED !
Thank you Ttelmah for your advice.
After I modified flash access from "16F 64/64" to "16F 16/64", it works correctly.
BTW, I added a line in main to accept my HW , the consumption of memory exceeded 2ff. The original code is just 0x2ff size. So I needed to change my HW.
