GAL22V10D not programming correctly

Hello,
I tried programming some Lattice GAL22V10D 15LP purchased from the asian market with the latest firmware / software.

Device: TL866II-Plus
Software: Xgpro v11.00
Firmware Ver.: 04.02.126

The JED file have the following ChkSum: 0x0000 03D9

Programming seems to be successful when "Verify after" is unchecked but when I read the chip the ChkSum is incorrect (0x0000 1704) and the Verify action is not successuful.

Same behaviour without the "Encrypt chip" option.
Note that the VPP Voltage was lowered down from 16V to 12.50V to prevent overcurrent issues.


I guess this is a bug in the most recent firmware / software.

Please help!

Thanks,

Fabrizio

Hello,
I tried the same steps with the last release of the software: Xgpro v11.10


Same behaviour: programming GAL22V10D seems to be successful when "Verify after" is unchecked but when I read the chip the ChkSum is incorrect (0x0000 1704) and the Verify action is not successuful.


Please help!

Hello,
you gave a feedback for the GAL16V8C but I still have problems programming the GAL22V10D.
TL866IIplus and software 11.20, the saved settings are not correct, I always get a verify error.

Please help!
