Unfortunately, I'm unable to program PC28F256P30BF (BGA64) with adapter XG-BGA64P2-1.0mm

Each time I have error buf_val 0xFF but ic_val 0x00 with different addresses.

As a User,
Hopefully is only a bad contact or resistance, on adapter side or chip side. Try cleaning both , or chip first, then the socket , then the rest.
Be carefully all the time

Hope it helps

I bought a programmer from another manufacturer with an BGA64 adapter, PC28F256P30BF was erased and programmed normally.
I repeat the same procedure on the T56 and I have error.

Chip erased with T56 and blank verified on other programmer successfully.
Chip programmed and verified on other programmer.
Then I read chip on T56, after I pressing verify I got error on address A, I close verify window, open it again, press verify and got error on address B, ....... got error on address C.

Your error is similar to mine. Pay attention to the firmware erasing time

Admins did not answer anything for 2 months with a similar problem.

Unfortunately, the length of the cable is 8 cm (cable comes with adapter)

I unsoldered all capacitors and checked. Capacitance is 0.1uF of each.
What else can I check?
