Hi,
We purchase a new unit GQ-4X and I'm having some troubles erasing and writing AM29F400BT flash.
I already try two different flash memory and one of them is brand new.
When I try to erase it stucks at 100% and the VCC/VPP leds is always on.
I'm using the ADP-019 adapter and it is correcly set to 5V and with the jumpers for 29Fxxx.
Can you help me? I never have this trouble with my old GQ-4X unit.
Thanks

Hi,
The SW and Driver version are the last provide from MCUMALL download section.
I already try the Temp. Un-protect and the problem is the same.
I have here a friend's old GQ-3X and with it I can erase and write just fine the same 29F400BT flash...
Can you help please?
Thanks

Try to check the Temp. Un-protect check box from software.
