Thanks for your reply. I used the 'make release' and copyed the release_oe eboot.pbp-only version. As I said, the usbhostfs_pc.exe is showing 'connected', and the problem is I got no response from the command console using telnet.exe Did you build from the psplink source tree, or the psplinkusb sour...

PSPLink 3.0 & usbhostfs on WinXP problem

I've checked out the latest psplinkusb source from the SVN tree, installed the driver, usbhostfs_pc shows connected, except when I telneted into the console and typed in the commands, nothing seemed to happen.

I tried the -vv, and Bulk Read always returns -116. Anybody has any ideas?

Did you run the 'toolchain.sh' or 'sudo toolchain-sudo.sh'?

On Ubuntu, should be the latter, if still doesnt work, try to go to the individual directories and manually 'make'.

Yes, it was said to be ported but no binary or source were released.
I found the problem might be the speed... with my default configure settings,
a freedos image runs even very slow on my 2.4Ghz duo core... :(

Bochs for PSP compiles

Remember I posted couple of threads about porting ucLinux to PSP. After trying for some time, I've decided to start with something maybe easier - a VM like Bochs. My intention is, if Bochs works on PSP, as least at 286/386 speed, we can have a more usable linux running on it. And console programs su...

Well.... just think about PDAs like those Windows Mobile devices, you'll find 32MB has no problem for multi-tasking and MMU. Though here, multi-tasking has a different definition, I suggest you to look at some of the WinCE developers' blogs. There're some articles on it. If you'd still like to have ...

Sorry if I didn't state myself clear enough. I should have said 'Multi-Tasking' rather than 'Multi-Processing'. Yes, PSP does have multi-threading, but as it doesn't need to have more than one process running at the same time, it doesn't really need MMU. WinCE PDAs need MMU because WinCE is a multi-...

Basiclly the same as any SDL.

For 2D it's more or less just about getting the framebuffer and start working on it. 3D is just like GL, I suppose.

Well, we are both talking about the same idea. What I want to point out is just TLB is the buffer and MMU is the unit. PSP doesn't need multi-processing and I think that's why Sony didn't put in a MMU. Some 32MB systems do have MMUs, like PDAs with PXA270. It's good that we discussed about the hardw...

MMU is key to virtual addressing, which is implemented in nearly all the modern mainstream OSes. In virtual addressing, each process will 'think' that they own a continous 4GB memory (32bit systems) - well in fact only 2GB/3GB available for them to play with coz the OS will take 2GB/1GB. But most of...

Thanks for those explanation. For my understanding, cache coherence problems would occur only when two client processes are sharing data. So it should be possible for letting some certain kernel process to run on one core, without exposing its resources, while all the other tasks are done by the mai...

PSPLinux project kick-off??

I've recompiled the PSPBoot and got Jasonm's PSPLinux running on my phat dsd (www.peidaqi.com). But even after days of effort, I cannot get the toolchain, nor the kernel built. I wonder if there is a group of people interested in this, and we could work together to bring this up. I've gone through J...

Anybody managed in building Jasonm's ucLinux toolchain?

I've downloaded the source code and patches from Jasonm's page. By recompiling pspboot, I got his pre-build kernel running on my phat dsd. But I'm having problems building the toolchain. Binutils and Gcc are working, but I was stuck with ucLibc (0.9.29). It's saying not able to find ./include/asm/un...
