hi:

i want to do some work about OMAP5912'GPIO.but I am failed to do that.

the following is a simple program:

test.c

-----------------------------------------------------

#include <stdio.h>
#include <unistd.h>
#include <asm/io.h>

#define GPIO3_OUT 0xfffbbc40 /* lp1 */

int main()
{
/* Get access to the ports */

/* Set the data signals (D0-7) of the port to all low (0) */ outb(0xffff, GPIO3_OUT);

/* Sleep for a while (100 ms) */
usleep(100000);
}
-----------------------------------------------------
arm-linux-gcc -g test.c -o test.out
----------------------------------------------------
I run the binary file on the omap:./test.out
-----------------------------------------------------
but i get the result:segmentation falt!
---------------------------------------------------
who can provide me with information? if you have done work related with gpio,would you like send me some examplefile?
thanks!

Hello,

I don't know if my idea help you.
Maybe the problem is about the libraries in directory /lib/ on OMAP file systems. It doesn't contain the libraries, which your program need.

Regard,
Thanh

Don't think you can access physical memory directly in user space. You should use /dev/mem instead.

thanks.
I get information about how to get use of the hardware in linux,but I am still confused about it.
-----------------------------------------------------------
the following steps about it:
1. apply for the resource to linux kernel
2. if you have applied ,then you can do some work about it.
3.if you have finished ,release the resouce.
-------------------------------------------------------------
i can only get the physical memory of the registers from the omap process guide.but I don't know their address in linux.
though it's a very basical question,i have to apply for help.
maybe a simple example can make me understand quickly!

                         thanks
                                    w.b.b

Hi all,

I am trying to look for steps as how to load program to my LDK5910 board which has omap5910.

Now Omap5910 has ARM925T and DSP.

We are able to load program,but not able to execute to ARM core using Code Composer Studio 3.1.We are trying to load boot loader and execute it to program flash through JTAG.

Also we trying to update/load bootloader using serial port. At this moment the default bootloader is not there in the board as we are thinking the flash would have corrupted and serial console output is not showing up in teraterm/hyperterm. All baud setting are fine as per document.

we are using rrloader as bootloader.

Is there any other option through which can load the program & execute in RAM/flash and write to flash.

Please share your input or help reference if any one has work on this board.

Regards
Raja Mallik

Check if section 2 of OMAP readme [1] can help you with JTAG and CCS. Maybe the other stuff in HOWTO section of OMAP Wiki [2] can help you as well.

Thank for the input.

Pl, give your input in this case..

Hello all,

I'm wondering how one would generate a random number on both the DSP and
GPP sides. Does linux come with a tool for generating random numbers? Should I include a standard (and large) math.h library for this purpose? I know the OMAP has hardware support for the generation of random numbers, but I can't seem to find refferences to how to use it in the BSL pdf. Any insight is much appreciated.

Thanks,
Andy

I have not tried my self, but have you seen the random generator driver in
drivers\char\omap-rng.c?

Thanks, pushing today.

Tony
