ok Thanks for pointing out my mistake. now it is giving a different error.
i did
unsigned long *funcs;
if(ioctl(fd, I2C_FUNCS, funcs)<0) {
perror("ioctl");
/* ERROR HANDLING: i2c transaction failed */
}
Now it says
ioctl: Bad address
i guess either the address is still incorrect or there
Hi,
I am trying to test tvp5150 with my board from userspace. i have written a
small program using example given in I2C documentation.
after opening file
fd = open ("/dev/i2c/1", O_RDWR );
when i do
if (ioctl(fd, I2C_SLAVE, 0xB8) < 0)
the system returns
Failed to set slave address: Invalid argume
I'm using emif to connect a FPGA FIFO outside. The FIFO width is 16
bit. To access the FIFO, the address is 0x04002000. I want to copy a
block of data to FPGA. I try to use edma to do the transfer.

acnt = 2;
bcnt = data_size(bytes) / 2;
ccnt = 1;

Hi,
I'm just writing some code that wants to implement a stupid mmap on a
device.
What I did is the following:
1 - allocating a buffer with kmalloc:
kmalloc_ptr = kmalloc(LEN + 2 * PAGE_SIZE, GFP_KERNEL);
2 - make sure that it's page aligned:
kmalloc_area = (kmalloc_ptr + PAGE_SIZ

Do you have the buffer allocated for the video plane you are intending to use?

Hi,all
I have a question on how to playback video on video framebuffer of
DM355.
Now,I want to use mplayer to playback a avi video file on /dev/fb/3.
I have transplanted mplayer successfully by this method

Philby,
Sorry, I forgot to mention, I did correct a problem with accessing a regs, it
is where yo usend a NACK. I changed the read from DAVINCI_I2C_IMR_REG to
DAVINCI_I2C_MDR_REG.
+flag = davinci_i2c_read_reg(dev, DAVINCI_I2C_IMR_REG);
+flag |= DAVINCI_I2C_MDR_NACK
i did modify the patch to work for the dm644x. I believe it is correct, I
looked at the 2.6.10 kernel and made the changes to your the i2c-davinci.c
after patching it with your patch.
It did nothing without the changes from the 2.6.10 kernel.

Sameer,
I would suggest you pick up a later DSPLink release for e.g. DSPLink release
1.50. This release officially adds support for a later version of the Linux
kernel under MVL Pro 5. You can either move to a DVSDK version supporting a
later DSPLink release or use the code files in a later DSP
Sameer,
This error is indicating patch has not been applied correctly.
Older support mails indicate this patch is for an older DVSDK version (1.00
series). Looking at the patch code, you should be able to patch the DSPLink
files manually.
Thanks and Regards,

Hello,
I have been trying to compile dsplink_140-05p1 (dvsdk_1_30_01_41) for 2.6.23

I applied the patches provided by Keven Hilman available here:

After a few changes, the build process works up until
