How to change the file Davinci_vpfe.c for capturing the Raw Data in my DM6446 platform?
Hi, all My platform have the FPGA modules as the video source, and I could get the video stream as the BT 656 format, and It works very well. Now I want to capturing the video stream as the Raw Data format from the FPGA modules, but I do not know how to change the davinci_vpfe.c to set the ccdc registers and the ipipe registers. could anyone tell how to do that for get the raw data from video source?

Why can not I ping several cameras for the same time?

That means when I make only one Camera working, I could ping it well, but two or more cameras works on, I could not ping them at the same time！ Anyone could tell me about some problems about that?

Could anyone meet this problem about Davinci DM6446?
Hi,all, I found a problem about the Encode Demos of the DM6446, that is the H.264 video only have the even fields from the VPFE source, because if I set the Y Factors as Zeros of the even fields of the VPFE video source, the encoded videos will have all the black frames, but the LCD srceen from the VPBE is not.

Could the video encoder of TI Encode Demo only process even fields of the video stream from VPFE?
Hi, all, I am afraid that the last letter can not discribe the problem detaily? My problem is: the video encoder only process the even fields of Line 0,2,4,etc. from DDR, but the display thread could process the odd fields of Line 1,3,5,etc. from DDR, and the writer only write the even fields to the local file. Both the encoder and the writer combine the even fields to the all fields, that is they copy the even fields as the odd fields so they could have both the odd and the even fields. Could anyone tell me if the problem is true about the TI encode Demo, or I get some mistakes? and Please let me know about my error.

Some questions about MontaVista Linux
Hi, Daniel, I am facing some probelms when I use the MontaVista Linux on my DM6446 EVM. 1. I am use the LargePage Nand Flash (ST's NAND01GR3B2B NAND Flash ) on my DM6446 EVM, When I use the MVL4.0 kernel on my board, I found that the kernel would scan all the blocks of the whole nand flash as bad blocks. However, When I use the MVL 5.0 Kernel on my board, the kernel would find no bad blocks of the whole nand flash. So I want to know how to update the MTD drivers for the nand flash from MVL 4.0 to MVL 5.0? could you give me some advies about that situation? 2. If the above problem would not be sovled correctly, I have to change my kernel from MVL 4.0 to MVL 5.0. While I found that the MVL 5.0 kernel could not mount the NFS correctly, the kernel would halt mounting the NFS for ever, the following is the messages: *===* *IP-Config: Complete: device=eth0, addr=192.168.0.125, mask=255.255.255.0, gw=192.168.0.1, host=XJTUIPCEVM, domain=, nis-domain=(none), bootserver=192.168.0.238, rootserver=192.168.0.238, rootpath= Looking up port of RPC 13/2 on 192.168.0.238 portmap: server 192.168.0.238 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 15/1 on 192.168.0.238* ** But When I use the MVL 4.0 kernel, I found that the kernel woud correctly mount the NFS with no errors. Between the two situations my u-boot ENV is the same configurations: *bootargs=mem=120M console=ttyS0,115200n8 root=/dev/nfs noinitrd rw ip=192.168.0.125:192.168.0.238:192.168.0.1:255.255.255.0:XJTUIPCEVM nfsroot=192.168.0.238:/home/workdir/rootfs,nolock video=dm64xxfb:output=pal* So I want to know whether there are some necessary differences about the kernel configurations between the MVL 4.0 and MVL 5.0 or not. Such as make menuconfig, u-boot env setting (bootargs, etc.) Thand you, Hope for your reply.

Re: Problem with YAFFS2 on LargePage NAND
Hi, Philby, I tried several steps as you suggested before, but the problem was not solved by now. and when I mount the jffs2, there are some errors printed by the kernel. and I want to know if the MV Linux Professional Edition 4.0 does match the LargePage NAND flash or not. You know, when I use the original source code of the MV Linux, the linux kernel scanned the nand flash as all the blocks was bad blocks. and my NAND flash info is the following: TI UBL Version: 1.14, Flash type: NAND Booting PSP Boot Loader PSPBootMode = NAND Starting NAND Copy... Initializing NAND flash... Manufacturer ID = 0x0020 Device ID= 0x00A1 Pages Per Block = 0x0040 Number of Blocks = 0x0400 Bytes Per Page = 0x0800 Valid MagicNum found. NAND Boot success. DONE So I want to find the reasons from this place, maybe there are some mistake in the configration of the MV linux kernel. So, WIll you give me some tips about the NAND configration in the MV linux? Such as the kernel configration, the NAND OOB info, the NAND ECC info, or the process of the BBT building. Thank you.

What modifications have you done in nand_bbt.c ? After your modifications, yaffs2 reports lesser error? How few are the reported bad blocks? All NAND based flash devices contain some bad blocks at manufacture, so if its really few then it shouldn't be a cause of worry. So what is your advice when you are facing this problem? I guess there may be some faults in the nand_bbt.c(driveis/mtd/nand)? Is it? I have no idea. But here are some steps you could do to narrow the cause of your problem. 1) Switch to jffs2 to see if the problem goes away. If yes, you could use jffs2 or start debugging the yaffs2 fs code. Turn on debugging using echo all /proc/yaffs before mounting the fs. 2) Switch to using btt on RAM instead of flash and see if the problem exists? You could so this by changing to this-options |= (NAND_USE_DATA_ADJACENT_OOB); in function nand_davinci_probe() - case NAND_ECC_HW_SYNDROME: ie: get rid of the NAND_USE_FLASH_BBT option. 3)Erase mtdblock4 partition from Uboot specifying the offset to the start of your nand fs and the size of your fs (mtdblock4) eg: nand erase 0x240 0x5e0 This will clear all your previous factory marked bbt entries, so use this at your discretion.

About MCP NAND for Davinci DM6446
Hi,All, I want to know if the Davinci DM6446 support the MCP NAND for booting from the nand flash or not. For my first version board, my nand flash is ST 's NAND01GR3B2B, which has the 8-Bit width organization. and my boss tell me that he want to use the Numonyx 's nand flash NAND01GR4B2C in my second version board, which has the 16-Bit width organization. But I found that the Numonyx's Nand Flash whose width is 16-bit width is only available for MCP products. So the question is: Does the dm6446 support the MCP Nand flash for booting from the nand flash? (the MCP nand flash device id is included by the list of IDs supported by ROM boot loader of DM6446) Could anyone tell me some info about that?

About the usage of malloc in the U-boot
Hi,all, Could anyone know about the usage of malloc in the u-boot, I found that when I try to require a space for nearly 800K using the malloc function, the return value of the malloc function is always zero. That means failure of the malloc funcion. I know that in the Linux Kernel the max required space of malloc is 128K, could the max space of malloc in the U-boot be less than 128K? My U-boot version is 1.2.0. If anyone have some info about that, please contact with me.

About the NAND boot mode for DM6446
Hi, all,
I have got two different ways to set NAND user boot loader descriptor
format, one is:
*Offset *
*32-Bits *
*Description *
0
0xA1ACEDxx
Magic number
4
Entry Point Address of UBL
Entry point address for the user boot-loader (absolute address)
8
Number of pages in UBL
Number of pages (size of user boot-loader in number of pages)
12
Starting Block # of UBL
Block number where user boot-loader is present
16
Starting Page # of UBL
Page number where user boot-loader is present
20
Load Address
Application load address, usually 0x20
the other way is :
NAND UBL Header
0x00 0xA1ACEDXX A valid magic number of the nand boot mode
0x04 UBL entry point32-bit absolute entry-point address for UBL
address
0x08 numpages the number of pages the UBL occupies
0x0c startBlock the starting block in NAND where the UBL
can be found
0x10startPage the starting page within the starting
block where the UBL can be found
could anyone tell me the right way to set the Descriptor of the NAND UBL
thank you.
and when I make the UBL in linux command line, I found that there is a
string The entry point of the binary is 0x2398 outputed, so what is it
means? please help me~~
if I use the UBL header static Uint32
ublheader[6]={0xA1ACED00,0x2398,0x001c,0x0001,0x0001,0x0020};,is
it right?

About the NAND flash boot
Hi, ALL, I have some problems about the NAND flash boot the UBoot, could anyone give me some advice about it? I make the UBL from the TI, and I conig the u-boot-1.1.3 source code for the NAND flash, and then I write them to the NAND flash by CCS, but when I set the btsel[1..0]=00 and set the EM_Width pin by the value Zero(Low), the NAND flash boot is failure and the chip autoly start boot from the UART, at that time the Chip is always sending the string BOOTME. Could anyone share the success version UBL with me or tell me the ways to resolve the problems, thank you. And I don't understand the linux code tree about the MTD, in the /include/mtd/nand/Nand_davinci.c, there is the codes during the line 173 and the line 174, #define MASK_CLE 0x10 #define MASK_ALE 0x0A But the ALE pin and the CLE pin of the NAND chip is connected to the address pin A1 and A2, I think the MASK_CLE and MASK_ALE shoud be set by the value (12) and the value (11), is it right? Although the MASK_CLE and MASK_ALE is set by the value (0x10) and the value (0x0A), but when I boot the kernel, the NAND flash is working well, why? Am I wrong？Can Anyone tell me?

RE:serial flash problem
Hi, Canibek, I think that you should read the documents to ensure if your NAND Flash is surpported by the NAND driver file,nand.c(SPRAAI4,page 26, table D-1), if not, you should appended your NAND ID to the nand.c Dirver. about the second question, you should set the kernel address and the file systems to the bootargs,such as bootcmd=boot 0x bootargs=mem=***,root=/dev/mtdblock3 noinitrd rw,** or bootargs=mem=***,root=/dev/mtd3 noinitrd rw,** Best Regards, shaofeng,zhang Date: Mon, 22 Dec 2008 14:47:04 +0200 From: canibek sa??n csa...@gmail.com Subject: serial flash problem To: davinci-linux-open-source@linux.davincidsp.com Message-ID: !!aaayaa4l0lqedzhahch6gvr1g7fcgaaaejliixvluxpciedish3q9ceba...@gmail.com Content-Type: text/plain; charset=iso-8859-9 Hi all, I am trying to load UBL and U-boot to my nandflash via sfh_DM35x.exe.

How to boot the chip from norflash with omitting booting from the USB HDD via DFU(Device Firmware Upgrade)?
Hi, everyone, I found that when I inserted the USB HDD to the usb port of the DVEVM 6446, the platform would not boot from the norflash, it would halt there for ever. but if I removed the USB HDD, I saw that the platform would boot from the norflash freely and start the kernel.Can anyone tell the reasons? I know that the AT91RM9200(ARM920T, ATMEL corp.) chip will start from USB port via DFU(Device Firmware Upgrade) protocol when it finished the DBGU and the USB device port initialization. Would the dm6446 chip firstly start from the USB device port via DFU yet? Please do me a favor.
