Use ETL 9S12
It can read-write it

[lucioantonio]

Not possess.UPA'not good to programm it?

[lucioantonio]

UPA can to write MC9S12DG256?

This MCU is secured,you cant read with UPA,
you need ETL...

Rosfar is more easy. No desoldering ;)

hello,
do you know if xprog could read and unlock this mcu?
wich is the mask?

[exe123]

of course xprog can also do it

[almeida]

hello exe123,
with xprog if i read a mcu with normal way, and if they are secured, xprog warning they are scured.
the board to read secured and normal way is different.
i have experience with upa, but i?m newbie with xprog.
for ex with upa when we read a 908 and they are scured they show the dump adadadadad and xprog?
thanks

of course it is different. for unsecured gnd, vdd, bkgd, reset is enough. for secured ones you will also need extal/gnd (coax-wire) and sometimes XCLKS

Can't remember what UPA is doing if you try to read secured one.

[Zmann]

If UPA was able to CORRECTLY read it even with some other different menu, the MCU should not be secured. When the MCU not read with the right menu, did it get 'bad' RESET in 'connections. Try to set 'Reset0 Time' and Reset1 Time' in Device>Settings to between 500ms and 1000ms and try again.

if the MCU is Secrured , UPA message will be "Device not Respond" because it cannot communicate in MCU
