I believe this might be a case of cache coherency, since you are using the same
buffer to DMA as well as allowing it to be cached.
Thanks,

Hi,
I have a little problem with my board, and my NAND chip is NAND01GR3B2B
which is ST corp.'s product.
When the u-boot start running from the NAND flash, there will be a warning
called " *** Warning - bad CRC or NAND, using default environment ",
and When I use the command "saveenv" to save th

Hello,
I'm using a 2.6.18 kernel on a specific davinci platform and I tried to
backport the last GIT MUSB driver. Unfortunately too much changes in the usb
core stack.
So I tried to compile the GIT kernel for EVM board, but I did not find any
davinci defconfig.
Do you know where I can find it?

Hi,
I'm trying to get out of a problem with a driver using EDMA.
In first instance, I wrote a simple module, that simply take from a fixed
address of a EMIF device and put it in RAM.
The transaction seems to go well, but I'm not able to have an interrupt
when the EDMA cycle ends.

Hello All,
I am using DM355 to send a chuck 4Kb of data using the DMA over the SPI
bus (mp is DM355).
The DMA is allocated for SPI channel 1 to the TX and RX events (event 14
and 15 are used).
The DMA is configured, in ASYNC mode. With SPI data register "SPIDAT1"
as the destination addres
Hello All,
I am using DM355 GPIO Bank 6 interrupt for one of the peripheral. We are
using the Montavista TI Davinci Linux 2.6.10 version.
I was trying to register an interrupt (IRQ = 60 for GPIO Bank 6 and the
GPIO used is 96) with Linux. It gave the invalid arguments. Then I did
debugging
Try request_irq(gpio_to_irq(96), isr, SA_INTERRUPT, "slave",NULL);
Then check /proc/interrupt.

Hello,
To test AV sync you need to use clip which has lot of talking (e.g news
channels podcast). I personally use animated clips for video quality test (e.g
up-scale/down-scale etc) not for AV sync. Use some podcast from here

This matches current GIT usage, so the MUSB code won't
need another gratuitous change.

This is a device driver for the NAND flash controller found on the
various DaVinci family chips. It handles up to four SoC chipselects,
and some flavors of secondary chipselect (e.g. based on upper bits

Certainly. Even *I* have done that ... and it's a sad year when
I have to boot into Windows even twice.

Hi Prabhaharan,
I also got the same kind of problem. I was using DM6467 GPIO Bank 2
Interrupt and the same kernel as mentioned by you.
I was trying to register an interrupt 58 for GPIO Bank 2. GPIO used by me
was 39.
Please follow the step mentioned bolow.
