Anyone know where the flash counter is stored on the Byteshooter Mini PCB. Not in Serial EEPROM so i guess in micro? Any ideas?

Cheers

The counter is integrated into the processor TMP 94 FD 53

what do you want to do by modifying the counter ... unlimited flashes? why don't you ask your master to do this for you ... he can set this to a high number.

TMP94FD53
The password storage area is FE2000 - FFDFFF, considering the single chip memory map.
This area corresponds to the Sprint memory range of 62000 - 7DFFF.
Any successive bytes within this area can be considered as password.
However, three or more consecutive bytes of the same data are prohibited.
The user must define the Password Count Storage Address within this area.
The content of this address is the password count (1 byte).
The password count is not allowed to be less than 8.
The user must also define the Password Comparison Start Address.
The passwords are compared beginning with this address.
If the comparison fails, the device can not be accessed by the programmer
(error message: "Ramload operation failed...")

To read (or verify) the content of a programmed microcontroller
- set the Password Count Storage Address (SFM)
- set the Password Comparison Start Address (SFM)
- fill the appropriate addresses with the correct count
and password, respectively. (EDITOR)
