Hi, I'm trying to develop a GUI for PSPLink 3.0 but by trying i found an error.
if i try the command "bpth" on any thread it crashes.
For example i tried this:
Code: Select all
host0:/> bpth "@SCE_VSH_GRAPHICS"
Exception - Bus error (data)

Now my question is, if this is supposed to happen or not?
Anybody has experience with PSPLink?

Sony have probably changed the thread context on newer firmwares and psplink is no longer compatible, unless someone can be bothered to figure out the differences it probably will never be fixed now.

Looks like I compiled it for wrong FW-Version.
Modified Makefiles.psp as followed:
Code: Select all
all:
$(MAKE) -C libpsplink all PSP_FW_VERSION=500
$(MAKE) -C libpsplink_driver all PSP_FW_VERSION=500
$(MAKE) -C libusbhostfs all PSP_FW_VERSION=500
$(MAKE) -C libusbhostfs_driver all PSP_FW_VERSION=500
$(MAKE) -C psplink all PSP_FW_VERSION=500
$(MAKE) -C psplink_user all PSP_FW_VERSION=500
$(MAKE) -C usbhostfs all PSP_FW_VERSION=500
$(MAKE) -C usbgdb all PSP_FW_VERSION=500
$(MAKE) -C bootstrap all PSP_FW_VERSION=500
$(MAKE) -C bootstrap kxploit PSP_FW_VERSION=500
now seems to work:
Code: Select all
host0:/> thctx "@PspLink"
kstack 0x00000000 kstacksize 0x00000000
stack 0x882DF900 stacksize 0x00010000
context 0x8822FF00, vfpu 0x00000000
Context EPC 0x88035364, Real EPC 0x00000000
...
host0:/> bpth "@SCE_VSH_GRAPHICS"
host0:/> 0x08947EEC: 0x0A251FA2 '..%.' - j 0x08947E88
exresume
host0:/>
But thx, problem solved. :)
