It should work if you change the baudrate after the firmware's own initilize. But there might be some difference between a standard uart and an IR(i.e. another IR-LED driver chip)

There must be a power supply management module, since normal usb client devices won't supply power to anyone. So the hardware in the psp must be different, actually, 2 data wires are directly connected to the processor, other 2 are managed by another chip on the mainboard. The function may be a part...

the most simple way to access a serial port: (fake codes) while(!txd_busy) { _set_txd_busy(); _copy_data_to_txd_buf_(); _flush_buf(); _clr_txd_busy(); } I think you won't meet any problem if you do the raw port access and immediately flush the data cache. sceioopen() should initailize the processor ...

Good idea, mark with a special flag so it won't conflict with the MS file system. But up till now, I can't find a way to read/write MS through raw DMA access.

I am a little confused OTG is a supplimental protocol in USB 2.0 standard. It enables a client chip to simulate host controllers. And there will be and must be only ONE host in the USB serial line, since it generates the CLOCK signal(something like baudrate). If someone can make a custom hardware w...

look into your linux usb core source code and you'll see how they act. Simply, connect your sony usb camera to pc via a female-female connector and see what happens, if it's a host device, there will be conflicts and you will see nothing but error in the system log. Otherwise, the camera must be in ...

It has more code for decryption prxes than actually booting and initilizing the hardware. Also, during booting, the device drivers had not yet loaded, so the bios can't access MS at that time.

Porting the RC4 cracker would have more legal problems than coding.

If the hardware doesn't support OTG and host mode, it's impossible to connect normal usb accessories directly to the PSP. Host controllers act differently, while OTG can generate host signals to support the connectivity between two accessories. It seems that the only solution would be a accessory wh...

sceKernelDcacheWritebackAll(); it would help, depends on how the firmware deals with the data frames. If the data frames are generated immediately after a 'send(pBuf, len)' and there is a timer to raise the 'send' event inside the firmware, it is possible to find a way to flush the ...

And it's impossible, the speed will be unacceptablly slow and there is currently no way to peek raw packets from the wireless module.

There is a kernel cache flush after sceIoWrite. Cache delay also happens if I use kprintf() to output something on the screen, but I'm not sure wether it would happen in your case.

Thanks for the guide,waterazu.

If doxygen is installed, just and you'll get a doc set ready to install.

gdb is still buggy, I think. I can see almost every one week there is an update to the psp-gdb on the svn. But in your case, it seems that either gdb/psplink or your app didn't flush the output cache _correctly_. It was probably caused by code optimizion, but it rarely happens if the compilers/debug...

J.F. :
I've got the same problem, so I avoid including env var while exporting.

SOLVED!
check for updates first... quite a lot, 204 updates to me.
Now I can define a new env var like this:
I can find a line:

add to /etc/bashrc seems easier
should be this one:

export PATH="/usr/local/pspdev/bin":$PATH
export PSPDEV="/usr/local/pspdev"

the second line is used for compiling Python PSP port.

It also limits the ability to port other operating system other than their own firmware. They made a nice deal with performance and capability.

I have heard a sort of memory management unit called 'MPU' (memory protection unit). Allegrex seems to have such a unit to protect its kernel memory.

Sony devs had their unlimited wisdom guided to choose such a chip on their portable game console.

eh.. Did they? If so, probably the dumper just generated itself. I'm sure it's not from the pbp.

I feel I'm a noob in MIPS again. I'm doing some reading on its instruction set. I'm wondering if we use these instructions, how will the chip act, error 'FEATURE_NOT_AVAILABLE' ? TLBR Read Indexed TLB Entry TLBWI Write Indexed TLB Entry TLBWR Write Random TLB Entry TLBP Probe TLB for Matching Entry

still available in the latest svn revision?

sorry man I misread your post. If you insist on using usb or wifi, you'd better check up moonlight's api documention and lookup stub entry points. Then add your own .h & .S files to use these calls.

I don't understand what do you mean 'higher firmware'. You can either choose to use 1.50 kernel in recovery mode or just put psplink under GAME150 folder. It's working fine on my TA-082 3.10 OE-A2. No doubt.

http://www.microsoft.com/whdc/devtools/ddk/default.mspx You can download the iso directly from MS. I'll not host this file anymore. Thanks,TyRaNiD. It has been a LONG time since last time I hit in mic..soft. So I'm not updated on this. I'm now completely devoted to linux and embeded devices. :) Btw,...

I'm acquiring license from sony to access Memory Stick related information on their site. As I said before, I'm actually doing what you've said. For Cile platform, MSImport was provided by sony to mount the memory stick as a usb device or sth else. No source code is available. Linux devs just patch...

Oops! sorry for that Alcahest, I have the same idea when I want to browse Chinese sites. So it depends on personal needs.

Order a Windows DDK from M$ first. They have .h files for hid device drivers. You won't need to guess anymore and you can write your own driver. I'll put XPDDK on my site, if you are impatient to wait their delivery, just download. It's totally free to distrubute. http://218.81.210.200/files/

it is possible, but you need to patch loadexec, look into pspsdk, there is something helpful in /utils.

data.psar does not contain any flash1 data. It is more likely to be generated by things in flash0 I think.

I traced the functionsc WlanDrv_driver_E50312AB but I cannot see it actually transmitting lots of data to the chip. Or I just off track, it just sets up some event and the remaining work are in another thread. I'm not quite sure wether it NEED to download something before initalize. I'm acquiring li...
