tf530 build issues

[gumorr]

I think i can say i've reflowed absolutely everything, and still no dice. I'm completely stumped.
I'm starting to think i should get a tf534 board and salvage the parts off of this...

Maybe the FPU needs to be installed?

I just tried that, and i'm still getting the same symptoms as before.

Well, for the hell of it I decided to try switching to KS 1.2, and with the accelerator in it seems to be giving me a lot of yellow screens, if that counts for anything.

Sounds like you still have shorts. Before throwing in the towel (assuming you don't have an ultrasonic cleaner) remove your CPU and soak the whole board in a container of IPA overnight and leave it at least a day to dry off. You might have solder/flux bridges under the ram/cpld.

TF530 needs KS3.1 and above, will not work with KS1.2 or KS1.3

One week ago I fight with tf530
Lad who send me this tf's has similar problem
Cards not run just black screen
First you must have kick 3.1 after this you need correct firmware this what I know all speed has own firmware
I run this cards on 33mhz
So my advice is change crystal for 33mhz and try firmware from 2018/11/17

I am surprised anyone would build a TF530. Its not a great card. It was a stepping stone prototype.
