MC9S12HZ256 EEPROM writing problem

[Andik]

Hello,

maybe, someone could help, I'm experiencing a problem with storing any data to EEPROM of HZ256 using same algorithm, as I use for e.g. DT256 (and working well).

I tried to burn some pattern into EEPROM and result is, whole EEPROM array is $00. Erase seems to work well, after that I can read $FF.

My HZ256 is member of 3L16Y maskset (QAD0620) and existing errata doesn't describe such a problem.

I'll keep on to find the reason, maybe I omitted some important difference in programming algo.

Ok, my problem is solved, I made mistake in bootloader, which uses another port. When I tried to program EEPROM via BDM, all worked. Sorry...
