Hello

I have a GQ-4X with a ADP-054 adaptator, i have permanently this error when writing on 27C322 :

Write failed, Address=0x200100, Buffer=0xFF Device=0x45

It happened 3 times with 3 different chips, same message, I suppose my adaptator has a failure because I can write on 27C801 without any issue

I am having this issue as well. I have moved J1 to short pins 2&3, but not J5. I will try that out.

In the past this has worked if I set the speed to 0, but it is no longer working.

I have tried this with 7 Chips, all pass the blank check but fail the write. I have 7 more coming in today that I will test this with.

Chip is bad?

owww my apologies, I thought this adaptator didn't required any jumper, I just saw them...Well it's never too late to learn...

Thanks for your reply, greatly appreciated I'll keep you updated if my trouble is still going on...

There is a 3 pins jumper, set it to left side for V3 and right side for V4.

Thanks for your answer but I don't get how I should switch with this kind of adaptator ?

If you got exact same error, then try to switch the J5 between V3 and V4.

Try to use a 9V external power and see if it works.
