This may be a crap CPU, have similar issues with at least 15x 33Mhz CPUs ive bought recently.
Try to swap it out for known good one :roll:

I’ve tried with one Motorola and one Freescale, both EC variants rated for 40 MHz. Guess I’ll try swapping in the Motorola that sits in my working TF534 (also EC/40 MHz) to see if that works.

I REALLY hope that it isn’t the CPU

The Freescale CPU works fine at 50 MHz in the other TF534, so that wasn’t it. Phew.

I’ll reflow the bus CPLD later to see if I have an intermittent connection somewhere.

Are you using a used CPU socket? I've had glitches with dirty / loose socket pin receptacles. To test this I put my CPU in at a slight angle so that the CPU pins make good contact. After verifying that it worked, I sprayed the socket with contact cleaner and the glitches went away.

I'm making my own out of brand new female headers. I've cut a jig for it in a CNC router and they seem solid enough. I've replaced the CPU in the first one multiple times without any glitches, so I don't think that's it.

Ok. An update more than a year later 😄

A year ago I started replacing the CPU socket, and while doing so I ripped some traces. Because I’m an idiot. And my desoldering gun had a bad tip.

So I shelved the entire thing and haven’t looked at it since. Well. I bought a PCB from @8 Bit Dreams. Then I shelved it.

Until today. Today I started transplanting the CPLDs, RAM, buffer and stuff to the new board. I think it went quite well.

We’ll see in a couple of days when I’ve got time to continue :)

Looks like your project and time management is on par with my own, I have more than a dozen Amiga hardware projects on the go ATM and I just keep buying more. :stars:
(eg. 3 x A2000 MB to repair, 2 x A1200 Re-Amiga builds, 4000ATX build, A1200 desktop build, CD32 repair and a assortment of open source PCBs to build) :dizzy:
I finally found the time to complete a couple of TF536 in the last few weeks so I am kicking some goals occasionally :roll:

I did find the 534 was a little more tedious to build than the 536

Good luck with the finishing the TF534,

I only work on hobby projects when I want to, so if I get stuck or mad I just put them away for a while while I work on other stuff :)

Yeah... Rub it in with the 536 will ya. I probably missed my chance :D
