I have been working with pushing images to dozens of Z90D7s running WES7 for my company for the past for few weeks. I haven’t had any problem using the Usb firmware tool until today. (I will say I’m running an older version, 1.13, as the new one’s don’t seem to work right or at all for us)
Anyway, today i was thrown quite a curveball that has me stuck. The new load of Z90D7s we got in keep throwing a “Security Key Failure” whenever i try to push our image onto them via USB. Or they simply hang at the “do you want to perform the push operation” prompt after selecting “y”. Mind you the same exact key works on all the other units i’ve had in stock, and continued to work even after they failed on these new units.
There are two difference with the new units though and I’m not sure if they could part of the issue or not. The model #s are the exact same, but the firmware is newer, 9.03 on the new one Vs. 9.02 on the old, and the new ones have 4GB RAM instead of 2GB the first batch had. Other than that they are identical.
It looks like you got the new, reworked Z-class units. The old ones had a AMD dual core 1.6 GHz CPU. The new ones have a ADM dual core 1.65 GHz and a newer GPU.
Can you try to pull an image of one of the new ones and push it to another new one?
