Hi Stephen, the video shows you programming the RAM first (fast forward to 7:42 mark):

[ Show youtube player ]

It is a TF328 though, and I think that may be where some of the confusion is coming from.

Perhaps there is another video?

Yes. The TF328 has ram cpld first then mux.

On the TF530 the Bus cpld is first then the RAM cpld.

I have my TF530 v3 almost complete. waiting on Resistors r1, r2, r3 the 030 and some jumpers and breakable pin headers.

My question is can I program the Xilinx chips without these parts? will have the Xilinx programmer tomorrow. I have the JTAG pins installed should have all other parts by friday

You need the regulator and JTAg header, and power to the 5V rail to program the CPLDs. Nothing else.

I recently built the TF530 for an A2000 that was given to me. I hit a few snags along the way, but it's basically started working. I need to debug a RAM issue (yay, AS7C4096B - AS7C4096A on order) and test the IDE port, but it boots!

Thanks, plasmab for all your hard work!

Thank you! and Thank you for all your had work! hopefully will have the CPLD'S programed tonight

Has anybody got a PDF version of the rev 3 schematic they could share?

I want to do some point-to-point testing before power-up.

Thanks!

Best way to do that is to use eagle or openboardview

Thanks! I downloaded Eagle and printed the schematic from there. I thought the trial version would complain about the board size (as it is limited to 8x8cm), but there were no issues.

In general the schematic is useless of point to point testing. I use the board view and highlight the nets I want to test. All the cpld connections are JTAg testable

plasmab you might want to get all your codes off github as microcrap is buying it , bad news for the whole world.

I have no issue with Microsoft these days. Apple is the evil empire

Having issues, I got the 530 R3 almost complete. I just need to install c16, c17 and the cpu. was holding off on this until I programed the chips.

After installing the 530 in the cpu socket I find the voltage regulator runs Hot! very hot. I have checked my soldering and replaced the regulator. I turn the power on only for a second and can feel the regulator getting warm so I turn it back off. I am wondering what would cause this? I need to check cap C-1 to make sure I installed the correct one. This is the regulator I am using

You have a short on the 3.3V rail. That’s the only thing that can do that

Thanks for the help Plasmab! So far the only think I can find is the 3.3v and GND on the JTAG header has continuity. That don't seem right, but Im no expert either.

I checked the CPLD areas under microscope, they seems fine. same with the area around the voltage regulator. but obviously I done something wrong or we wouldn't be having this conversation

Thank you

Well you definitely have 3.3V shorted.
Remove the passives from the 3.3V rail first.. then the crystal... then keep going until the short is gone. Sorry but thats the deal.

Thank you! looks like a bad solder joint at the oscillator.

Got the TF530 installed but can't program the chips. xilinx has the green light. if I initialize the chain I have the 2 chips listed both are uninitialized and marked bypass. loading a .jed file I get a error data mismatch and unknown jedec file.

if I do a boundary scan then load the .xsvf then execute it, I get a error did not complete sucessfully. otherwise all other functions work. Erase, blank check, readback ect.. all work.

am I missing something?
