Just want to make sure I understand, you can boot the board with the binary that comes with DVSDK, but you can not boot the board with the binary generated by following the "Getting Started Guide" If that is the case, what are the commands you used to configure and build the kernel and what error did you see during boot up?

why can't i compile usb host and gadget at the same time?
Dear all: I want to use gadget for u-disk device and host to connect a usb printer in the dm355,I now used Linux Kernel v2.6.10_mvl401 ,when i make menuconfig to select usb driver mode,the options is: ( ) USB Host ( ) USB Peripheral (gadget stack) (X) Both host and peripheral: USB OTG (On The Go) Device if i select 2 option,i can use command "insmod g_file_storage.ko file=/dev/mmcblk0p1 removable=1 " for u-disk device. but if i select 3 option, I failed ,The module can been insmod ,but the windows PC cann't identify the u-disk device. I wouldn't use the host and gadget function at the same time,but why can't i compile it together?

zuowenping,
You need to modify the arch/arm/mach-davinci/davinci_spi_platform.c
struct spi_board_info dm6467_spi_board_info[], .modalias =
DAVINCI_SPI_EEPROM_NAME, to .modalias = "spidev". Also you must enable
CONFIG_SPI_SPIDEV. After that the kernel will detect the device as
"spidev0" and that should get spidev_probe() to work. I think :)

Re: Can i give the capture buffer address to fbdev or v4l2 for displaydirectly?
I have studied the v4l2 display driver,it supported V4L2_MEMORY_USERPTR mothod,it seemed can accept a buffer address but it must be mmaped to the display buffer first,So the captured buffer datas must translate to the mmaped buffer,so the result is equal to mmap display buffer directly. V4L2_MEMORY_MMAP : v4l2 capture buffer->address1(mmaped) -> EDMA-> address2 (mmaped)<-v4l2 or fbdev buffer V4L2_MEMORY_USERPTR :v4l2 capture buffer->address1(mmaped) -> EDMA-> address2 (mmaped)->v4l2 or fbdev buffer 2009-07-09 zuowenping 发件人： zuowenping 发送时间： 2009-07-09 19:35:44 收件人： davinci-linux-open-source 抄送： 主题： Can i give the capture buffer address to fbdev or v4l2 for displaydirectly? dear all: I am now using dm355 for capturing 640x480(30 frame / second) picture and displayed in svga mode 800x600(60 frame / second) by ths8200.if i used edma to translated data from v4l2 caputured buffer to frame buffer, It will emerge noised pictures,i have set PBBPR register with value 30 .but if i change to displayed in vga mode 640x480(60 f/s),it seem ok!it seemed the ddr speed(171M) is not enough! but My project GUI(osd) must be set as 800x600,So i have to change displaying to svga.I don't want to used edma, then can i give the displayer driver(fbdev or v4l2) my caputre buffer address directly? 2009-07-09 zuowenping ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source

how can i add spi1 or spi2 device in the kernel linux2.6.10 of dm355?
I have to use spi0 and spi1 in dm355 on the same time,I have modified the
davinci_spi_eeprom driver(it used spi0) to communicate a device sucessed! but
now when i wanted to add spi1 driver for another device to kernel, it didn't
work! I add source as bellow:
static struct spi_board_info dm355_spi_board_info[] = {
...
#if SPI_1098
{
.modalias = "spi_1098",
.platform_data = NULL,//&davinci_8k_spi_eeprom_info,
.mode = SPI_MODE_0,
.irq = 0,
.max_speed_hz = 200*1000,//2 * 1000 * 1000 /* max sample rate at 3V */ ,
.bus_num = 65535,
.chip_select = 1,
},
#endif
.
}
And i have register a spi driver spi_driver :
static struct spi_driver spidev_1098 = {
.driver = {
.name = "spi_1098",
.bus = &spi_bus_type,
.owner = THIS_MODULE,
},
.probe = spi1098_probe,
.remove = __devexit_p(spi1098_remove),
};
By the printk information, spi1098_probe cann't been call, And i only find one
device (spi_eeprom) in /sys/bus/spi/devices/ ,so the driver cann't been
matched! then how can i add spi1 or spi2 device in the kernel? Any hints will
been appreciated!

Hi Duke Zuo,
We are also struggling with similar issue since few weeks. We have done some
investigation that might help you.
1. What NAND chip you are using?
2. What is the page size? As per TI, RBL does not support NAND having 4096 page
size
3. Are you able to do UART boot?
4. Have you modified anything in “NAND_Programmer.pjt” source code? If yes,
what are those?
5. It is surprising to see your changes related to ALE/CMD address, we are not
required to do so.

主题： RE: RE: nand_programmer check all nand flash blocks error
Hi Zuo,
Could you pls elaborate more on “change nand flash type to HY27UG088”?
Are you physically changing the NAND flash or doing software changes?
Also when you skip the NANDCheckBadBlock () function, you said the ubl and
uboot seems burning ok, but when you reboot the board, it can’t boot!!
So can you read 32 bits of ARM internal memory (0x7ffc-0x8000) via JTAG and let
us know what you are getting.

Here is what you could try. 1)Try using jffs2 and see if the problem occurs. If not then its a yaffs2 specific issue, which I suspect. 2)Type the following commands in the same order in your UBoot //wipe out bad block markers >nand scrub >nand erase clean >nand erase Please be warned. The following commands will wipe all information including Uboot, boot args location, anything else that's on the flash. If you cannot do that specify offset and size to the above commands for the mtdblock3 partition. 3)If your flash supports 2K page size and the device uses h/w ecc could be that yaffs2 marks all blocks as bad cause it cannot write 32 bytes of extended tags to the spare area, hence showing no useable space left. You could define YAFFS_IGNORE_TAGS_ECC and try mounting yaffs2 again.You could check parameters after boot up by typing >cat /proc/yaffs 4)If you are in a mood to debug your problem (assuming the trouble is with yaffs2), switch on debug using >echo all > /proc/yaffs Regards, Philby On Fri, 2009-02-13 at 15:01 +0800, zuowenping wrote: > dear all: > I use a new nand flash,and i make 4 partions for > bootloader,params,kernel,filesystem > when i use a ramdisk for run the kernel success! i operated like: > flase_eraseall /dev/mtd3 > mount -t yaffs2 /dev/mtdblock3 /mnt > dh -h > > # df -h > FilesystemSize Used Available Use% Mounted on > /dev/root 9.7M 8.0M 1.2M 87% / > tmpfs 966.6M 11.9M954.7M 1% /tmp > /dev/root 9.7M 8.0M 1.2M 87% /dev/.static/dev > none 10.0M 2.5M 7.5M 25% /dev > tmpfs55.8M 0 55.8M 0% /dev/shm > none 55.8M 12.0k 55.8M 0% /var/run > none966.6M 11.9M954.7M 1% /tmp > /dev/mmcblk0p1 966.6M 11.9M954.7M 1% /tmp > /dev/mtdblock3 1016.0M 1012.4M 3.6M 100% /mnt //puzzled 100% > so i cann't load my rootfs, All files used over 10M size! > 2009-02-13 > > __ > zuowenping > ___ > Davinci-linux-open-source mailing list > Davinci-linux-open-source@linux.davincidsp.com > http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source

I have tested and it is ok,but my mtdblock3 has no bad blocks for the rootfs area,I'm not sure if it has,what will happen?it seem only support jffs2 by the name command "nand write.jffs2"! 2009-02-15 zuowenping ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source

Re: RE: the u-boot size
I think you have to modify nbl programmer in ccs3.3 envirment ! it just read
two blogs from nand flash.
#define APP_DESC_START_BLOCK_NUM 8
#define APP_DESC_END_BLOCK_NUM 9
if your nand page size is 64k,it equal 128k!
and you no need to modify nandprogrammer ,because it can accept blogs from 8 to
14(checked it in source)!

U-Boot descriptor is located at block # 8.
Its format is:
/* Some of the parameters are modified runtime */
unsigned int appdesc [] = {
0xB1ACED22, //Magic number
0x000A, // Start block in NAND
0x8108, // Start address in DDR
0x8108, // Entry point
0x0200, // No. of pages for the complete Application
0x //compression flag
};
You need to update descriptor as per your requirement.

Dear all:
Recently,i modified the u-boot of DM355. Now the size of u-boot is 129KB. When
i updated the u-boot using the u-boot self, the system reported error. But if i
used the old version which i modified yesterday, the size is 127KB, everything
is OK.
the command line:

can anyone test mt9t001 ok in dm355?
Dear all:
We used a FPGA which just like a CMOS Sensor for inputing raw datas to dm355,So
I want to test device_type mt9t001 on dm355 evm to verify the driver whick
capture raw data is ok. I have modify the demos encodedecode program source to
support mt9t001 for test.
..
/* Use either NTSC or PAL depending on display kernel parameter */
//std = V4L2_STD_PAL;//gblGetYFactor() == NTSCSTD ? V4L2_STD_NTSC :
V4L2_STD_PAL;
std = V4L2_STD_MT9T001_VGA_30FPS; //edit by duke 2009.2.17
if(ioctl(fd, VIDIOC_S_STD, &std) == -1) {
PTRACE(LOG_ERR,"VIDIOC_S_STD failed on %s (%s)\n", V4L2_DEVICE,
strerror(errno));
return FAILURE;
}
/* Set the video capture image format */
CLEAR(fmt);
fmt.type= V4L2_BUF_TYPE_VIDEO_CAPTURE;
fmt.fmt.pix.width = VGA_WIDTH;
fmt.fmt.pix.height = VGA_HEIGHT;
fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_SBGGR8;//V4L2_PIX_FMT_UYVY;edit by
duke 2009.2.23
fmt.fmt.pix.field = V4L2_FIELD_INTERLACED;
/* Set the video capture format */
if (ioctl(fd, VIDIOC_S_FMT, &fmt) == -1) {
PTRACE(LOG_ERR,"VIDIOC_S_FMT failed on %s (%s)\n", V4L2_DEVICE,
strerror(errno));
return FAILURE;
}
.
and i haved set bootargs .for example:
setenv bootargs mem=116M console=ttyS0,115200n8 root=/dev/mtdblock3 rw
rootfstype=yaffs2 ip=dhcp
davinci_capture.device_type=0
video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16,2500K:osd0=720x576x16,2025K
davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=$(videostd)
the the programer can run ok,but it cann't capture data!!
Is it hardware problem or soft problem?
I thinks dm355 only suport cvbs or svideo input,so how can i input raw datas
to mt9t001 for test in dm355 evm?
thanks all!

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.

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.

I can't boot linux2.6.18 uImage in dm355
dear all: I used the DaVinciLSP-01_20_00_014 in the past ,now i want to use the DaVinciLSP_02_00_00_110 because i want to use the linux2.6.18 kernel, so i use toolchains mvltools5_0_0 to compile the new kernel and it produced a uImage,but when i download it to the dm355 evm,it cann't been booted: DM355 EVM # tftpboot TFTP from server 10.0.0.89; our IP address is 10.0.0.53 Filename 'uImage'.

It stop here forever,it seems the kernel can't been booted,why?I used the old kernel uImage linux2.6.10 or i used the uImage-dm355 the PSP_02_00_00_110 supported,they are all ok! the arm_v5t_le-gcc i version is 4.2.0 (MontaVista 4.2.0-16.0.32.0801914 2008-08-30) ,I compile the kernel image steps is: make ARCH=arm CROSS_COMPILE=arm_v5t_le- davinci_dm355_defconfig make ARCH=arm CROSS_COMPILE=arm_v5t_le- uImage I have compiled too many times linux2.6.10 kernel in mv_pro_4.0.1 envirment just like up steps,they are all ok! 2009-05-13 zuowenping ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
sdio for dm355 problem
hi: I am using sdio stack driver in dm355, the dm355 using two sd card slots ,when i insert the first sd card,It show the device name /dev/mmcblck0,the second sd cards i inserted it show the name /dev/mmcblk1, But we often forget which sd card i first inserted or we inserted two sd cards before the kernel booted, So I want to bond the slot with device name,for example,if i insert the sd card in the front of board,it show the device name /dev/mmcblk0,then the name /dev/mmcblk1,how can i modify the sdio driver source to realize it? 2009-12-24 zuowenping ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
