Program problem PC28F256P30BF (BGA64) PC28F256P30BF, BGA64

Test

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

Test

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.

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.

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