TF328 for A1200 (Edu board)

Post by arkadiusz.makarenko »

I just build Edu board TF328 for A1200, and I can't make it work.
My biggest worry is parts from UTSource. Only one that had rams not in bulk. I got cplds from them as well, I am not sure if it was good idea.
How could I go and troubleshoot it?

Diagrom doesn't see anything and computer doesn't not at all with it.

Ps. I am not even sure if I built sources the right way, they do build all right with no errors do I guess it should be ok?

The best way to make it run - is to ask Eduardo:
info@arananet.net
He assured this design is 100% working

As about UTSource - will NEVER ever buy something fom them..

Weird :)
I got it working, and correctly detected when connected to external 3.3v source (Raspberry Pi for programming), but freaks out during ZII detection without it.
CPLDs might be ok, need to look at regulator

Edit:
And Firmware as HDD doesn't work..

Leaving connected RPi to board was terrible idea.
Now it doesn't see JTAG chain at all. Even working devices. Oh well, time to buy programmer,I guess.

EDIT: RPi 2 RIP ... all GPIO ports fried, I think It shorted out as I left it on metal shleld ... I have ordered cheap Xillinx programmer.

With TF328 firmware (don't have means to reprogram it just now - unless RPi Zero can be configured) and external 3.3V source
Amiga Test Kit and Diagrom detects and test 8Mb 100% right.

My Power issue is 100% regulator. They don't do good job in regulating, definetly they are not 3.3V (Even if they are marked as 3.3V).
Note to myself chineese suppliers fake EVEN regulators :/

And this is what killed my RPi, but for some reason CPLDs did survive .

Those CPLDs are hardcore. That’s why I use them

+ there is no better solution for the glue logic that is 5v tolerant:)

I have set up RPi Zero and flashed then with right firmware. All works great now :) Ram is on soak test. So only cleaning flux left.
