Problem writing EEPROM part of STC15W204S flash

[poli9208-cell]

Hello,
When writing eeprom part of flash of STC15W204S at 90% it says "error bad magic"

I figured the problem is that STCGAL doesn't fully erase all EEPROM sectors,
so I share my (adhoc) solution to this:

Change line 1742 of protocols.py, the part where it says

packet += bytes([0x01])

change it to:

packet += bytes([0x02])

so it forces erasure of all EEPROM sectors.

That's it!
