Is there any recommended ways for debugging IOP modules, when an IOP reset is used? Is there any way to redirect printf's from IOP modules to be sent over an ee_sio cable?

I believe the ps2sdk/iop/deug/sior module is for the sio cable. There is an sio_printf function in there. I havent used it myself so I am not sure.

Thanks for the lead, but I can't load the module:

The IRX is trying to bind with a Remote Procedure Call (RPC) Server on the EE side. You need to link with libsior.a on EE side and call SIOR_Init to create the RPC server, preferably before you load the module.

Thanks, I figured there had to be something on the ee side, I just didn't have any idea what. (And documentation is kinda lacking in the sdk)

printf seems broken in the sior irx module
It crashes the console, after printing one character(Granted I had need need to be using printf, it was just a constant string)
Using puts works fine, and I can always combine with sprintf to achieve the desired result.

Again, thanks for the help guys.

Hmm, I was just coming over to the forums to search for that, I vaguely remembered reading that topic(but at the time was uninterested in the iop)

Thanks for the tip on how to do it as well.

Edit: wow the ee version of printf is crazy, I found a simpler implementation(which does what I need it to do, basic debug) written for embedded systems, and it seems to work well.
