Phoenix stuck in reset

[russellnash]

I started installing the components on my Phoenix board. What a beautiful work of art it is. I powered it up and got a white screen. The reset pin was only getting 1.3 V. When I bridged 5V over it booted.
On the LS07 chip above the CPU pins 13 and 9 are at 3.3V and pin 12 has 1.3V that appears at the reset pin. I don't know anything about the newfangled reset circuit but I thought maybe that chip isn't doing what it is supposed to?

Did you do the reset patch that kodak80 did on his last week?

I think we need to ascertain what revision of the H5 he has before he starts doing mods.

[kodak80]

What revision board do you have? Mine as mentioned above is an H5 A3 revision.

Close up pic on the reset chip would be nice. Maybe it is soldered upside down? Or faulty.

It is one of the last two H5 C1 boards from four weeks ago. I have seen Kodak80's thread, it seemed to be about damaged traces. I haven't trashed any yet. Here is a close up.

Do you have this jumper in place here: viewtopic.php?p=52258#p52258

JP14 FLASHY CLOCK jumper on the centre two holes of the 4 hole below the Flashy Clock 3V3 Bus socket.

EDIT: If you have a picture of your whole board it can help us spot if any other jumpers or other things might out of place

As @Icky states, sounds like you not got a jumper in place. Possible your missing others also.

Yes, the middle two holes are connected.
I just thought of something. This board has multiple layers of traces, I think, not just at the top and bottom. All I have done is soldered a piece of wire over the two holes. It tests as closed circuit at the top and bottom of the board, but if the connection is in the middle of the board there is nothing actually going trough the hole, so that would mean it isn't connected. Maybe that is the problem?

[Icky]

Soldering across is fine as the holes if there are traces in the layers are all collected to the plating that goes through the whole hole.

Can you send a picture of the whole board as we may spot something.
