Re: RE: Problem about DSP server config of DM6446
Hi , Robert
I wonder is it a limitation of RMS(Resource Manager Server) or DSP/BIOS ? I
will modify my code now.
Thanks a lot.

主题： RE: Problem about DSP server config of DM6446
I'm not sure about a document, but the number of algorithm objects that you can
create depends on the size of the memory block from which the stacks are
allocated. As you've seen, cutting the stack size down allows you to create
more. You might be able to find a formula, but the real answer is as many as
you have memory for.

Hi all ,
In my application , I have to create one algorithm many times .
Fistly I config DSP server's CFG file and set stack size to 16384 in
Server.algs {} , but app can only create 7 instances of my algorithm . Then I
fix stack to 4096 and I can create more .
My question is How many algorithm objects can I create . Which document
describe it indetail ?

what I am missing here with DVEVM kit? How to solve this issue.
Hi :
I test the TMX320DM365 for h264 encode/decode demo by TI TMX320DM365 DVEVM
kit.
Running the Demos from the Command Line:
Target $ cd /opt/dvsdk/dm365
Target $ ./loadmodules_hd.sh
A issue occur as follows:
Target $ cmemk: no version for struct_module found: kernel tainted.
CMEMK Error: CMEM phys_start (0x8500) overlaps kernel (0x8100 -
0x85c0)
insmod: error inserting 'cmemk.ko': -1 Invalid parameters
Can anybody please let me know, what I am missing here with DVEVM kit? How to
solve this issue.
Thanks!

This should be 'CONFIG_MACH_DAVINCI_DA830_EVM'.
You man it wouldn't be applicable to DA830 boards other
than that EVM??
Maybe, maybe not.
Same comment in a few other places. From what you've said,
these are chip-specific issues, not board-specific ones...
Well, there are lots of pinmux conflicts on the da830. For devices
that aren't used all of the time, it makes sense to allow the driver
and the resources it requires to come and go on demand--maybe even the
console if there is a graphic console.
Either way, what uart is used for the serial console is determined by
the board not the chip.

Mouse and Keyboard Events
Hi, I am using linux-davinci-2.6.10 kernel (Montavista 4.0), I am using the Input Event Interface to capture and process events in my application. When using mouse and standard keyboard, everything works well. I am able to capture all mouse and keyboard events. But if i connect a mouse and a multimedia keyboard, i do not get any events from the mouse device. while the keyboard device delivers its the events. I also tried the evtest utility http://tiexpressdsp.com/index.php?title=Evtest but i am seeing the same results. One thing that i have noticed is that if i connect the mouse, then open the mouse device and then connect the multimedia keyboard and open the keyboard device, i am able to capture both mouse and keyboard events. So far i have been unable to locate cause of the issue. Any pointers in this direction would help a great deal. NOTE: (1) i am not using the /dev/input/mice interface for the mouse, but instead using the respective /dev/input/event* interface. (2) the multimedia keyboard creates two input interfaces, which through some research i found is absolutely correct.

RE: Mouse and Keyboard Events
Sameer, DaVinci USB IP supports limited number of endpoints in hardware and hence the limitation in supporting both multimedia keyboard and mouse simultaneously. In the configuration were in the mouse is connected first and then the multimedia keyboard the events from the multimedia controls would not work if mouse and key press functions work.

RE: RE: Problem about DSP server config of DM6446
You might review the Server_getNumMemSegs()/Server_getMemStat() API calls
(available at runtime after Engine_open()). These provide statistics about the
memory resources on remote processors.
Calling these services after each codec create/delete may help you better
understand memory usage on the DSP.
Finally, note that you could also run out of other resources - e.g. DMA, HW
accelerators, etc. So it's not just out of memory that can cause a codec
create to fail.

Or, you could reduce the memory to CMEM, increasing the phys_start address on the 'insmod' command in loadmodules_hd.sh. You can start it right at the end of the kernel memory. If the kernel goes up to 0x85c0, you can change to use phys_start=0x85c0 .

So the page fault is coming from the notifier_call. Then commented out this print and put equivalent in arp_init [net/ipv4/arp.c], rebuilt, and rebooted. Oddly now it gets passed the previous point (there are log messages in the console), but it fails later with a page fault at different location. arp_netdev_notifier = 0xc02ed7cc arp_netdev_notifier.notifier_call = 0xc01e0f74 So by moving the printk the address of notifier call is different/valid. I'm not sure how to proceed and any debugging tips are appreciated. The PC invalid (0x34767068 is not a valid RAM address). It is likely you jump to that location via uninitialized or corrupt function pointer. You can try to disable Ethernet in kernel config to see if you get pass this point. If you don't get this error, that means the problem is in Ethernet initialization/driver.

[PATCH] ARM DaVinci: Adding CONFIG options for NAND ALE and CLE
The CLE and ALE for DaVinci DM644x is not the same as DM646x. This patch
adds 2 CONFIG_ options to the config.h header files to all the DM6446 based
boards. These values are then used by the driver. This has been tested on the
DM644x, DM355, DM357 and DM365. Support for the latter 3 will be added soon.

[PATCH] ARM DaVinci: Adding DM357 Support
Patch adds support for DaVinci DM357. This SOC is very similar to the DM644x.
The DM357 EVM has 2 NANDs, one small page NAND and another large page NAND.
But the device can only boot of the small page NAND. It does not have NOR
support. This patch has been tested on the DM357 EVM.

Re: [PATCH] ARM DaVinci: Adding CONFIG options for NAND ALE and CLE

The CLE and ALE for DaVinci DM644x is not the same as DM646x. This patch

I had been thinking that the davinci_nand driver should
probably change to let board_nand_init() really become a
board-specific function...
It would call a driver routine to init the callback functions
and set up private data so that for example the 2GByte NAND
could be properly treated as a single device with two chips,
instead of two separate devices. (As Linux does; I'm just
assuming that mechanism works right in U-Boot.)
Other private data could include CLE/ALE masks, if needed.
I may well have missed something, but I thought that the
ROM on all chips used the same mask values when booting
from NAND flash... but that non-boot chips might end up
using different values, if they wanted. (Burst memory
access would work better if toggling low address bits
didn't affect ALE/CLE, etc.)
Alternatively ... how about just letting those values be
defined in the headers if the boot-from-NAND defaults
shouldn't be used?
That is, the u-boot davinci_nand.c code could
#ifndef CONFIG_SYS_DAVINCI_NAND_CLE
... #define it to the default 0x10 ...
#endif
I think the convention for these things (toplevel README) is
that since they're hardware-specific, CONFIG_SYS_* is the
prefix not CONFIG_* for those symbols.
Related: MASK_ALE should not be 0x0a by default, but 0x08;
right? That's what newer docs say; I think the old stuff
was just a bug. In Linux, 0x08 works just fine.
And for that matter, include/asm-arm/arch-davinci/nand_defs.h
is starting to look almost un-necessary after those cleanup
patches I sent. :)
This has been tested on the
DM644x, DM355, DM357 and DM365. Support for the latter 3 will be
added soon.
I'm glad to see TI's latest U-Boot work becoming public...
However, this won't apply on top of the cleanup patches I just
sent, which remove the NAND_CE0{ALE,CLE,DATA} symbols in favor
of the relevant nand_chip pointer. As you know, that change
is important for support of the EVM boards which include the
socketed 2 GByte NAND chips, with multiple chip select lines.

RE: Audio Driver Problem
He means to use a user-space application that opens up /dev/mem and manually writes to hardware registers. In this case, if the stall goes away when you write to that register, a pending transfer event not being processed could be the issue. The other case I had to fix in the 2.6.10 audio driver (when I was getting stalls) was to check the EDMA Missed event register, and to make sure that that got cleared properly.

This is because DM357 is very similar to the DM644x. If you want me to put a dm357 file then I will have to make an exact copy of the Dm6446 file.
