Confusion regarding DVSDK 3.10 on DM6467
Hi,
We are planning to use DVSDK 3.10 for DM6467 (729 Mhz) based
customize board. I have some confusion regarding the DVSDK version
to be used for development purpose.
DVSDK_3_10_00_19_release_notes.pdf page-4 says that "This DVSDK
release does not explicitly support the older DM6467 EVM
platform. Users who have the older DM6467 EVM are currently
advised not to upgrade from the existing DVSDK 2.0.0.22."
May I know why this limitation is there? Can't I use DVSDK 3.10 for
DM6467? And if I use DVSDK 3.10 for DM6467 what challenges I may
face?
Please revert back. Thanks in advance!

DM365 OV5642 interface: No video data.
Hi, I am trying to interfaced OV5642 image sensor with DM365 processor. The OV5642 image sensor is sending YCbCr 4:2:2 interleaved data with separate VSYNC, HSYNC and PCLK. I am capturing 1280x720P data from OV sensor. The PCLK is coming at 24MHz, VSYNC is at 7.5 fps and I am able to see the data coming on all data lines using CRO. On the DM365 side, I have configured the ccdc in YCbCr_SYNC_8 mode and I am receiving the interrupts at regular interval but when I see the data in frame buffer, it has definite pattern ( 0x02,0x03,0x02,0x03) . The register dump file is attached hereby. Also, I have following queries. . Do we need to configure PPLN,SPH,LNH,LNV register? As per our understanding, the ISIF will internally take care based on VSYNC and HSYNC signals that are Coming from external sensor. Sensor data lines are connected to CIN lines and so we are setting YCINSWAP bit as 1. Please confirm. Can anyone offer help on solving this problem?

DM6467 AAC audio encoding process fails with -Os compiler flag.
Hi All, These days I am working with DM6467 AAC codecs in which I am facing a strange issue. I have written a sample application for encoding. If I use -Os complier flag to within my makefile to compile the application the process call for encoding fails with error: -1 and extended error: 0x4008 . If I remove -Os flag from the application makefile everything works well. Well the solution is there that I should not use -Os flag :) but I want to figure out why this is the case. Can anyone tell me what can be the issue?

Re: DM365: how to use UART1 instead of UART0
Hi Steve, I want to use UART1 be the login console and for the bebug message both. UART0 will be used for some other purpose in our application. Well, I have successfully tested loopback on the UART1 by shorting Tx /Rx in which RS232 level converter is bypassed. But I am not able to transmit/receive if I connect RS232 level converter between DM365 and console UART cable. I think this might be a hardware issue in the level converter. I will try to figure out this tomorrow.

DM365: How to set USB_VBUS pin.

Re: DM365 UBoot + NAND Query
Hi Guys, Thnaks for the support. I have solved this issue. The problem was in the FPGA logic which was enabling/disabling the CE0/1 signals for NAND devices. Ideally for NAND-1 CE0 and NAND-2 CE1 should be high which was swapped in my FPGA code. I concluded this by probing the CE0/1 signals on the scope. I fixed this swapping error in FPGA code and everything is working well now!!!

One thing to note is that the Chip ID of 0xd3 can actually correspond to several layouts of the NAND. The kernel seems to read the proper info and adjust accordingly but U-boot may not. If you are using 2.6.10, you will need to go through and increase several of the arrays because they do not handle the larger layout (4224 bytes) and will overflow and cause ECC errors or even lockups. If you are using 2.6.18, you will also want to either turn off the use standard layout option under the kernel config (Drivers-MTD-Nand, somewhere below that) OR you will want to make sure U-boot is using the larger layout. I have seen the exact error you seen and fixed it by changing the array sizes and disabling the Davinci use standard layout option. This puts newer kernels back to the 4-bit ECC as opposed to Software ECC. Some versions of the kernel may have broken HW-ECC though.

If it's completely erased then writing about 512MB (0x2000) should cross into the second chip select. But wear levelling abstration layers may move things around or leave gaps. I would try Steve's u-boot approach: 1) In u-boot, use the nand commands to erase, write, and dump.

DM365 UBoot + NAND Query
Hi, I am working on a DM365 based customize board which has two nand chips each of 1GB. At the UBoot level I am getting following errors: *UBoot Log:* ** U-Boot 2009.03 (Mar 18 2010 - 20:23:55) I2C: ready DRAM: 128 MB NAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit) *Bad block table found at page 262080, version 0x01* *Bad block table found at page 262016, version 0x01* nand_bbt: ECC error while reading bad block table NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit) *Bad block table found at page 262080, version 0x01* *Bad block table found at page 262016, version 0x01* nand_bbt: ECC error while reading bad block table 2048 MiB In:serial Out: serial Err: serial My concerns are: 1.

Please let me know if it is really intentional or just a logical error.
This not specific to DM365 or to any device for that matter. However,
retrying infinitely when not using NFS does sound unnecessary. If you
find the same behavior in the recent kernel, you could report to netdev
list. You should at least get an explanation on why things are the way
they are.

Am I missing something in this source code or having wrong source code? -- Regards, *Krunal Patil* ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
Problem with DMsoc voice codec on Dm365
Hi, I want to use the M1(mic) on DM365 EVM as sound input. I modified the demo application to read data from MIC (M1) and write it to a file by commenting the encode call and its working fine. But when I modified and run the encode application to use new sound device with the command ./encode -s test.g711, it could not encode and giving following errors: *Error: Failed to encode speech buffer (Demo application prints)* *SPHENC1_process() failed with error (-1 ext: 0xa) (Print kept in DMAI source code) *If I use the default kernel and the default sound device to run the encode application, it will run well. Can anyone tell me what is going wrong with the encoding in case of M1(mic)?

IPIPE memory allocation failure.
Hi, I am working on a DM355 based system which consist of QT GUI and backend applications. The backend applications are responsible for MPEG (1024x768) / JPEG (1920/1080) capture/display and G711 audio capture/playback. For resized JPEG display (1920x1080 - 768x576) I am using DM355 IPIPE module and successfully able to resize JPEG image without any corruption. The problem is when I run the system for *a long time and hard/soft reboot* it the next time IPIPE memory allocation (IPIPE_REQBUF ioctl) of size (1344 * ((1080 * 2 + 31) (~31))) = 2924544 fails. System has 128MB of DDR out of which 108M are given to Linux kernel from the bootargs. Can this issue be related with memory fragmentation? Anyone please suggest me some pointers? -- Regards, *Krunal Patil* -- _ Disclaimer: This e-mail message and all attachments transmitted with it are intended solely for the use of the addressee and may contain legally privileged and confidential information.

Re: trickle mode in h.264 codec
Hi, I agree with Jeremy. You can not perform fast fwd, rewind etc operations on encoded stream easily. This becomes very easy if you use any container formats like QT, MP4, Matroska etc. Container formats have ability to mux various audio video streams with proper synchronization. You can also perform stream, compression operations at the same time you can also associate your events using container formats. Let me know if I can help you more on this or any case you need more information how container works. -- Regards, Krunal Patil eInfochips Ltd. Tel.No. (079)26563705 Ext. 120 Cell.

I mean: how can I implement fast forward / fast rewind / frame skipping / gop skipping in both directions? Or do I have to open the h.264 files and struggle with the h264 headers ? In general, you can forget about fast rewind--it is prohibitively hard to do with temporally compressed codecs. And presumably you'll either have to open the files yourself, or use some third-party API for working with container formats. (for example, if you're saving h264 to an mp4 container, you could use mp4v2 or ffmpeg) You could also save raw h264 to disk (raw bytestream), but there typically isn't timing information present, so it is unsuitable for playback applications. Also, is there a simple solution to implement file muxing? H.264 + (say) G.711 + proprietary data ? For H264 and G711, your best bet is an AVI container. G711 is not a standard part of the MP4 container format, AFAIK. I'm not sure about newer containers like matroska. -- _ Disclaimer: This e-mail message and all attachments transmitted with it are intended solely for the use of the addressee and may contain legally privileged and confidential information.
