I have been through numerous posts on the forum regarding the XD card mod on a slim but needless to say details are a bit sketchy. Ya see I am itching to get on with my personal project console and simply too impatient to wait for shipping of a cygnos (if I can find one) or even for the release of the DemoN and inevitable wait for suppliers to get orders out.... So I have decided to give it a go anyway!
I have been going by this image for the switch between onboard NAND and XD Card and it has given me some interesting results so far... Not too sure if its normal or not so thought I would ask the experts.
I dont have the switch or XD card in place, nor do i have the red wire cabled in. I am purely working with the mainboard, the resistors, the purple and orange wire, an for testings sake... a 3.3v LED
I have cut the trace and wired the orange and purple wires with 2 resistors as shown in the image and created the two following situations;
Switch Wires Joined - I get a 'Ding' But No Boot (assumed trying to find the non-existant XD Card)
Switch wires open - I get a Boot on OnBoard NAND
For experimental purposes I proceeded to solder a 3mm 3.3v LED in between the orange and purple wires. I now get a successful boot to the onBoard NAND and the LED will flash sort of like a read/write indicator to the TSOP when I interact with the dashboard.
Whats confusing me is the fact that before when i had the switch wires joined it didn't boot and I assumed it was looking for the XD card. but now joined with an LED in place which I assume creates the same kind of circuit It boots successfully every time....
Have I not cut the CE trace properly? could a cold solder joint have caused my initial failed boot? Does anybody know if the console should boot XD card NAND or onBoard NAND with the orange and purple wires joined?
Any advice would be appreciated EDIT
Just to confirm, I have now removed the LED and we are back to the first situation (Wires Joined = No Boot / Wires Open = Perfect Boot)
