[edit] A question for redcoat Is there any advantages/disadvantages to making the ps2 DTE, or is it really just the same thing?[/quote] A simplified answer is that they are the same, but the Rx and Tx are swapped around. On my setup I have a 9-pin male connector sticking out of the top of the PS2 (t...

So i was wondering if it will work with a MAX3227E ??? From what i can tell it does pretty much the same thing. I had similar thoughts about using a NTE7142, until someone pointed out it had to be powered at +5V minimum and would use +5V for the EE side :(. My advice is be extremely careful about m...

Gak! Another of my mistakes pointed out to me by Drakonite! :P OK, I double-checked the ps2link v1.22 source code and yes I'm completely wrong, v1.22 does load the ps2dev9 module. * Hangs head in shame and sobs quietly in the corner. So...what this all means is loading ps2dev9.irx a second time (via...

ps2hdd relies on ps2dev9 indirectly - ps2hdd uses ps2atad which uses ps2dev9 - so if they aren't playing nice together then there's a serious problem. ps2atad uses ps2dev9!? So how have I been able to successfully access the HDD (directory listings, copying files to/from HDD) without having ps2dev9...

My understanding, and experience, is that ps2dev9.irx and ps2hdd.irx don't play nice together. I suggest you trying excluding ps2dev9.irx from the list of modules you load. I've experienced the same problem with ps2hdd.irx freezing on the "Checking log..." message. This also happens when I...

You put PS2LINK on the memory card with the exploit. What the exploit does is run a program off of the memory card. No CDs involved. IMO, what Drakonite meant to say is you don't have to burn a CD, but you will need a PS1 game CD involved to run the program off of the memory card. (the PS1 game CD ...

Just a quick update, I discovered that the wire to the EE's Rx pin had detached on my PS2. After 14 attempts I finally got the wire, via, and solder to make friends and stay together. As mrbrown says "gently scratch the surface of the via to remove the soldermask that covers it." Even afte...

I don't claim to be an expert, but I've had a lot of experience with the SIO board over the last several days. Can someone provide a small code snippet on how to test? Sure, see the code and makefile below. My thanks to "tyranid" for sending the original code to me ;) The makefile needs ma...

Caveat: If you are following mrbrown's instructions from his web site (see http://www.0xd6.org/ps2-ee-sio.html) or his chapter in the book "Hardware Hacking" (see Chptr. 9 of http://www.amazon.com/exec/obidos/ASIN/1932266836/qid=1095575718/sr=ka-1/ref=pd_ka_1/104-2057502-5534309) you *mus...

Eureka! It's working! And, more importantly, I understand why it wasn't working before. Caveat: If you are following mrbrown's instructions from his web site (see http://www.0xd6.org/ps2-ee-sio.html) or his chapter in the book "Hardware Hacking" (see Chptr. 9 of http://www.amazon.com/exec/...

I've built the SIO board and soldered the wires to the PS2's mainboard (v4 afaik). Trying to solder to a 'via' (approx. 1/2 millimeter in diameter) is definitely a nerve-racking experience, especially when you know that too much heat will destroy the 'via' and possibly your PS2 too :S. Both the PS2 ...

I have have code (EE & IOP) which prints out the registers and a stack trace if anyone is interested. After that, I moved on and have gdb running on both the EE and IOP. Life is much nicer now that I've [re-]entered the 1980's... Symbolic debugging: stack traces, breakpoints, printing out compl...

I can't know if my function are called, nor what I should exactly do there. I am now out of ideas. Does somebody have some spare for me ? :P Here is an idea for you to find out if your exception handler function has been called or not. Have your handler generate a specific byte code sequence in the...

Ironically, I have been pondering the issue of IOP exception handling and reporting over the last couple of days. My first couple of simple EE-side apps caused exceptions, but ps2link has that very handy exception handler builtin to give a register dump (on the PS2's screen)--my thanks to pukko &...

That's probably not going to be enough. When I tried to build ps2link v1.24b I discovered the following dependencies: /----------------\ | ps2link v1.24b | \----------------/ | | | v | sbv-1.0-lite | | | v | ps2lib | | v v ps2eth Legend: A-->B : A needs B, therefore build B first, then build A! And ...

If you open my toolchain.sh script with a text editor, you'll see instructions like which environment variables need to be set. :) ( http://www.oopo.net/consoledev ) Yes, I did look in "toolchain.sh", honest! :) The additional environment variables I found I needed to define where: PS2LIB...

Excellent! Thanks apache37.

Now, you see I didn't know about this "-miop" option for "iop-gcc".

I think mharris is right, you definitely need a FAQ around here so newbie won't keep bugging you with silly questions :wink:

I tried your (apache37) suggestion, and changed all occurrences of "start" to "_start". This just gives the same error about "_gp" being undefined(?).

I believe that "start" is correct. My recall is that C and Asm identifiers are prefixed with "_" (underscore) by gcc/gas/ld when they build their internal symbol lists. Though, I confess I haven't found any online reference that supports my recollection. However, look at the 'man...

Speaking as a newbie, myself, I think this would be an excellent addition to ps2dev. I'm sure the ps2dev team get tired of the same old questions coming around. My two cents worth of suggestions are: - list common mistakes, and how to fix them, - what environment variables should be defined in your ...

I'm attempting to build an IRX module for the IOP. I've been studying the "Hello IOP" tutorial that I downloaded from http://ps2dev.org/files/helloiop.zip. I've detailed the problem below, what I need to know is: Am I using the right version of the toolchain? Is this a known problem? How c...
