Subject: [PATCH] ARM: OMAP: Remove IVA IRQ bank

ARM11 can't access the IVA interrupt controller from
IVA slave port.

From Richard Woodruff:

"The 0x40000000 is an IVA-ARM7 local bus address.
The IVA-INTC is NOT accessible through the IVA-L3-Slave Port.
The current TRM does say this directly and indirectly in a few spots and
in figures."

GPIO OF OMAP5912

[w.b.b]

[-- Attachment #1: Type: text/plain, Size: 1007 bytes --]

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!

AW: GPIO OF OMAP5912

[LIMITED Nguyen Duong Thanh (CR/AEM Praktikant)]

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

Loading program to OMAP5910

[Raja Mallik]

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.

Random Number Generation

[Abot Botbot]

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?
