    I think I've decided that whatever is wrong with the power supply goes away after it's been on for a while. It's like something has to warm up...

    Just tried PX on it and I think it worked. Saw Propeller Hat LED flashing and serial leds flashing while programming and then Prop Hat LED stayed solid for a couple seconds and then RED LED 0 lit.

    I'm guessing that we first write to a flash memory chip over serial and then FPGA is programmed from the flash chip. I'm sure Chip said how this works, I just didn't pay attention...

    BTW: I had more issues downloading the latest files, this time with a new Win10 setup and Edge browser. Wouldn't let me download due to security. Am I the only one having this problem? Had to use IE10 and then override security...

    PNut now recognizes board and loads all_cogs_blink example and I've got 12 flashing green leds. So, I guess I'm in good shape.

    I just noticed that I should have read the "readme.txt" file in top post of the P123 board sticky thread download. It mentions how to use PX and also that there might be an anti-virus warning...

    It doesn't say, but I guess the top.rbf file programs the FPGA to emulate P1?

    Yes... the P123 was released first and the .rbf file for the p1 was released after that.
    As I recall, it is set for 80MHz, so you need the pll to have it work reliably... unless you get lucky as Ozpropdev was:)
