Re: How to make the DVSDK working along with the git kernel

Hi,

I also want to run demo software on git kernel, and started building components

Due to the changes in header file locations lately in arm tree, all machine 
specific includes have to be changed in source files and build scripts must be 
modified to accomodate new header locations. Some changes also needed for new 
kernels which can be found in [1]. Also one little change is needed for 
"post-processing" step to build kernel module.

After all these dplinkk module builds, but it is not working!!! However, I have
another issue which might also cause this. I'll investigate this later.

cmemk builds fine without any changes.

Request : USB CPPI DMA patch for DaVinci (2.6.23 git kernel)

Hi,

I am working on Davinci platform & using 2.6.23 git kernel. Can you
please provide me the USB CPPI DMA patch for 2.6.23 git kernel.
It will help me to measure USB performance with DMA enabled
on our custom board.

Thanks and Regards,
Padmanabha.s

DVSDK and uclibc Target

Hi,

I'm in the process of building DVSDK with the current git
kernel and seems like I arrived at a dead end.

I'm using eabi uclibc toolchaing. Thus I set my target as 
UCArm9(a470uC) when building examples. However, a470uC 
libraries in codec engine and framework components are build
without EABI*, so I can not link my binaries with codec engine
(also framework components). I can switch to a glibc toolchain 
or I can use a OABI uclibc toolchain. Both options I try to avoid.

Is it possible to rebuild CE, Framework components, etc with a 
EABI uclibc toolchain? (I guess not) or do I have any other option?

Regards,
Caglar

Re: how can I play the video of dm355?

Hello,
If you want to play the file locally using VLC, then
	rename the file to     <some_file_name>.*m4v*

But if you want to stream it and play it over rtsp then you need to
modify your rtsp streamer (from live555 example) in order to parse the
short header generated by DM355. More information on this can be found
here http://wiki.davincidsp.com/index.php?title=DM355_Codecs#MPEG4_Encoder

Cheers
Kumar

IRQ request dm6467

Hi all,

I have some issues with IRQs for the gpio 12 configured as input. The aforementioned gpio is used as an IRQ triggering source. Whenever i load my module everything goes well, but when i start triggering interrupts with a pulse generator, everything hang and  there is no possibility to do anything anymore. Since I'm using two console to see what is happening (by reading kernel messages) i could notice that the IRQ installation succeed but the ISR is never called. Besides that, there is no other kernel message, so that i could not find out what went wrong. I'm using the mvl 2.6.10 Kernel on the DM6467 evm.
As follows you can take a look to a code snippet and maybe help me wit h that.

 //gpio configuration
      gpio_input = 12;
      gpio_output = 11;
      gpio_irq = gpio_to_irq(gpio_input);


// Not sure if necessary, but once again switch gpios on
  board_setup_psc(DAVINCI_ARMDOMAIN, DAVINCI_DM646X_LPSC_GPIO, 1);

// Set pinmux to enable gpios
   __REG(PINMUX0) &= ~(1<<2);
   __REG(PINMUX0) |= (1<<1);
   __REG(PINMUX0) &= ~(1<<0);
  
    gpio_direction_output(gpio_output, 1);
    gpio_direction_input(gpio_input);

/* Enable irq on falling edge*/
  struct gpio_controller *__iomem g = gpio2controller(gpio_input);
    u32 mask = __gpio_mask(gpio_input);
        __raw_writel(mask, &g->set_fall ing);
        __raw_writel(mask, &g->clr_rising);

  //set BINTEN for bank0
    __raw_writel(0x1f, (void *__iomem)IO_ADDRESS(DAVINCI_GPIO_BASE + 0x08));

  /* Request interrupt line for bank 2 */
    if (ret = request_irq(gpio_irq, gpio_driver_isr, SA_SHIRQ , "davinci_gpio_ir", &dev_gpio)) {
             printk(KERN_INFO "GPIO: Interrupt %i request can't get assigned!\n", gpio_irq);
            goto clean;
    }
  
Thanks in advance

Regards

Stan.

RE: Requesting for help:Ramdisk booting problem:

Chander,
 
To boot after downloading the ramdisk image and uImage, you should use "bootm <address of uImage> <address of ramdisk image>".

Re: IRQ request dm6467

I could find out what the issue was, so no need for help anymore.
I had a bug in my ISR.

Since I'm using two console to see what is happening (by reading kernel messages) i could notice that the IRQ installation succeed but the ISR is never called. Besides that, there is no other kernel message, so that i could not find out what went wrong. I'm using the mvl 2.6.10 Kernel on the DM6467 evm.
As follows you can take a look to a code snippet and maybe help me with that.

 //gpio configuration
      gpio_input = 12;
      gpio_output = 11;
      gpio_irq = gpio_to_irq(gpio_input);


// Not sure if necessary, but once again switch gpios on
  board_setup_psc(DAVINCI_ARMDOMAIN, DAVINCI_DM646X_LPSC_GPIO, 1);

// Set pinmux to enable gpios
   __REG(PINMUX0) &= ~(1<<2);
   __REG(PINMUX0) |= (1<<1);
   __REG(PINMUX0) &= ~(1<<0);
  
    gpio_direction_output(gpio_output, 1);
    gpio_direction_input(gpio_input);

/* Enable irq on falling edge*/
  struct gpio_controller *__iomem g = gpio2controller(gpio_input);
    u32 mask = __gpio_mask(gpio_input);
        __raw_writel(mask, &g->set_fall ing);
        __raw_writel(mask, &g->clr_rising);

  //set BINTEN for bank0
    __raw_writel(0x1f, (void *__iomem)IO_ADDRESS(DAVINCI_GPIO_BASE + 0x08));

  /* Request interrupt line for bank 2 */
    if (ret = request_irq(gpio_irq, gpio_driver_isr, SA_SHIRQ , "davinci_gpio_ir", &dev_gpio)) {
             printk(KERN_INFO "GPIO: Interrupt %i request can't get assigned!\n", gpio_irq);
            goto clean;
    }
  
Thanks in advance

Regards

Stan.

Re: SDHC on dm355

Hi, 

> Have you tried using these custom patches from TI? There was a recent

> LSP 1.20.

I looked into LSP 1.20 pack(*) and i was not able to find anything about 
SDHC. (and ideed my montavista kernel doesn't recognize a SDHC card )

Did I miss that some magic should be done??

(*) with patch level 14, of course.

Thanks, bye!

Psplash on DM355 and how to ./configure ?..

Hi all,

I want to add a boot status image  while linux booting on my DM355 application board. Did anybody use psplash package for this purpose. I have downloaded the package and when i try to configure with ./configure I get the following error:

./configure CC=arm_v5t_le-gcc CFLAGS=-I ~/workdir/lsp/ti-davinci/include

configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: /home/antaresian/workdir/lsp/ti-davinci/include

checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

waiting for a help...
