6 years ago what command line are you using? Are you writing separate code and eeprom sections? Are you trying to overflow your code into eeprom (can be done, but with a trick required...)

6 years ago I've tried both (separate files and combined). Dump shown is when using two separate hex files for code and eeprom space. Command line looked like something like this (but with -D to get debug info):
c:\python36\python.exe stcgal.py -P stc15 -p COM7 -b 19200 -o eeprom_erase_enabled=False -o reset_pin_enabled=False -o clock_gain=high -o clock_source=external -o reset_pin_enabled=False code.hex eepr.hex
I've tried a few combinations with and without -P and -b and various options, but I always got the exact same "Protocol error: incorrect magic in write packet". Looking at the dump data it is exactly offset 0x2000 where the eeprom starts in the STC15F2K08S2.

3 years ago Please try again with proper MAX232-based serial interface/s if any available. Also checkout carefully the VCC level, 5V vs 3V3, I had similar problems and they were really caused by that, see e.g.: Trivial solution to "bricked" STC15s
Kind regards and good luck!
Hi, Unable to flash STC15F2K08S2 stops at 13% (I assume when it starts writing EEPROM area).

Any idea what I can do to make it work? Thanx, Peter
