Need to understand PSPLink

[AllSystemGo]

Hi,

I just finished installing PSPLink on Ubuntu and I would like to understand how to analyse the messages it sends me.

1- I get this once I start pspsh

Code: Select all

2-

I would like to know why once I run the pspsh and get the error up there I can't run it again. I get this error

Failed to Load/Start module 'host0:/iPDA.elf' Error: 0x800200D9

Thank you for your help

Cheers

EDIT: I would like to add that I'm using M33-2 Firmware!

1.) That's an exception, or a crash. The best thing to do is run this via command line:

psp-addr2line -fe whatever.elf/prx EPC/RA

NOTE: '/' in the above line represents 'or', so you would type one or the other, not both.

In this case, your EPC is 0x0895BD1C, and your RA (Return Address) is 0x089005D8.

The 'whatever.elf/prx' is the target file from your makefile.

TARGET = myapp

If you compile it for the 1.50 kernel, then you would pass 'myapp.elf', and 'myapp.prx' for the 3.xx kernel.

For this to work you need to add '-g' to the CFLAGS in your makefile (It tells the compile not to strip debug symbols).

Running psp-addr2line with the options I showed above SHOULD give you a line number that will help you to find the source of the exception.

2.) The error, 0x800200D9, means that the PSP was unable to allocate enough memory to launch your application. Most commonly this is because you ran your application once, then tried to run it again, putting it into memory twice. Just type 'reset' into the pspsh shell to reset pspsh and try running your application again.

Wow this is the best explaination ever!!!

Thank you very much for your help I realy appreciate it

BTW: Does it matter if I am using the Firmware M33-2. If it does what should I do exactly??

DUH... That's what it was. You had to type reset to fix the problem. That's what it was. Thanks PSPJunkie, I tried helping AllSystemGo earlier, but it never dawned on me.
