Searching RAM (in VSH mode)

[kralyk]

Hi!

Id like to perform something similar to what CWCheat does, but in VSH mode...

How do I do that?
Do I simply make a pointer and increase it?

Very basic search, no DMA or anything - I just want to search for a certain value in RAM in areas where photo or video vsh modules are...

never mind, figured out myself...

I assume that was the answer...
to define an array, and then search with an index that extends beyond it's boundaries?
It appears to work in my programs.

Or you can just define a pointer at starting position and increase it while searching... array works the same, indeed...

In my code I actually dump whole block of ram to ms... The code
can be found in psplinkusb in file shell.c and decodemem.c

You just need to declare a pointer to the user memory.
If you declare u32 pointer you can access each 4 bytes like an int.
If you declare a unsigned char you can access it one byte at a time.
Or you can just declare pointers for all data types. Its going to consume like a couple of bytes only :P and use each one where appropriate.

Code: Select all

unsigned char * umem = 0x8800000;
#define UBOUND 24*1024*1024;
umem[0] = byte1;
umem[1] = byte2;
...
umem[UBOUND] = byteat24MB;

On the Slim the UBOUND for user memory will be different in VSH mode.
