That is reassuring. It is strange that i have exactly identical behaviour on two cards though. But it could of course be bad soldering or cheap ebay parts (only CPLDs and memory were from DigiKey). I just wanted to share my experience since it was identical to CRPs

I have applied the instructions but it does sound a bit weird. If inverting the jed does not cause any damage I might try inverting the jeds.
When i re-read the wiki I found that the Raspberry Pi part was copied directly from the TF328 wiki. And on that card it seems the CPLDs are the other way around in the jtag-chain.
I just noticed the wiki has been updated 8 days ago, but to me it really looks like it still states them in the wrong order? I could be wrong, and i'm sorry for the confusion in that case (compare with the stated order in tf530/bin/README.md).
