AM335x kernal3.2 SD boot up

Hi,

The information you have provided is insufficient. Please answer the following:

From your log I can see that the board you are using is the AM335x EVM. Is this correct? Why are you trying to use StarterKit kernel with it?
Where did you get the file 335xevm_sk.tar.gz from?
Which SDK/PSP version are you using?

Please provide answers to those questions.

Best regards,
Miroslav

Hi Miroslav,

   Sorry, I make a mistake with 335xevm_sk.tar.gz instead of am335xevm_sk.tar.gz. I compiled the anroid kernal 3.2 which came from TI-Android-ICS-4.0.3_AM335x_3.0.1.

I modified mmc driver  in the arch/arm/mach-omap2/board-am335xevm.c But it stuck there .so why?

  Please give me some help.

   Best regards

   Eason

Hi Eason,

The only changes you have done are inside the board file, right? Please post your board file here, so that I can take a look at it.

Best regards,
Miroslav

Hi Miroslav,

My board file is modified as follow:

  Please give me quickliy response, thanks;

5773.board-am335xevm.c

Hi eason,

I still didn't catch what platform is that? My actual question is: which dev_cfg structure is used for initialization?

Best regards,
Miroslav

No direct experience with the AMR335x. Some guesses. Looks like you short-circuited around all that complicated EEPROM dependent board configuration code and used hard-coded initialization calls. Noticed that some pins have moved from the LCD to the SD Card. Perhaps some other code is grabbing your SD pins. Maybe try commenting out initialization of other modules like LCD to see it SD can progress farther. I assume your SD card has 2 partitions on it and it properly formatted and initialized.

Hi Miroslav,

  The platform is  TI-Android-ICS-4.0.3_AM335x_3.0.1 .I didnt choose any dev_cfg . I just set  mmc0_init(0 ,0)  to initialize mmc . You can see it in boardfile. I am a newer .

Sorry, I appreciate your help.

   Best regards

   Eason

  Yes , the SD card indeed has three partitions on it . Some boot files is placed in first partion,because it boots from SD.Others are filesystem and video .There are  no problem in pins configure. Beacause I could boot from nandflash.The LCD works well. SD Card could be detected. Thanks  for you response.

The bootload does show the card being detected with size, speed, etc being read out. The next line should be something like "p1 p2 p3". Stateing the obvious, the MMC driver is hung up reading out data. The driver seems have gotten past the initial handshaking.

Is this a custom board? Did you get better results with other versions of the kernel? You mention NAND boot. In NAND boot, can the SD Card be mounted after boot?

     In NAND boot,  it can detecte the SD Card., but cant  mount.  

    The vold.fatab is that 

    dev_mount sdcard /mnt/sdcard 3 /devices/platform/omap/omap_hsmmc.0/mmc_host/mmc0

    dev_mount usb /mnt/usb2 auto /devices/platform/omap/musb-ti81xx/musb-hdrc.1/usb1

  The bootload log  show the SD boot .So you cant see the "p1 p2 p3 " .It just  stop when it mount the filesystem.

Hi Eason,

I noticed something that seems to be wrong in your mmc0_pin_mux:

    {"gpmc_ad13.gpmc_ad13", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP},
    {"gpmc_ad12.gpmc_ad12",  OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP},

Pins gpmc_ad12 and gpmc_ad13 can be pinmuxed to signals gpmc_ad12 and gpmc_ad13 respectively, but these signals should be set using OMAP_MUX_MODE0, not 7. I suppose you wanted to use signals gpio1_12 and gpio1_13 respectively, which are set using OMAP_MUX_MODE7. For more information please refer to Table 2-7. Ball Characteristics of the AM335x datasheet (page 27).

These strings are later used by the mux code to determine the corresponding signal. I can't tell for sure if the second part of the string is really important as I didn't over-inspect the code, but please try to correct this and report the results.

Best regards,
Miroslav

Miroslav, I believe the Linux MMC driver operates using GPIOs for CD and WP. It does not use the MMC controller's SDCD and SDWP. The DVSDK board-am335xevm.c used mcasp0_aclkr.mmc0_sdwp and spi0_cs1.mmc0_sdcd in MODE7 or GPIO mode. That said, the mmc0_no_cd_pin_mux uses mcasp0_aclkr.mmc0_sdwp in MODE4 or SDWP. These bootlogs lines

[ 2.303161] mmc0: host does not support reading read-only switch. assuming write-enable.
[ 2.314117] mmc0: new high speed SDHC card at address 1234
[ 2.320343] mmcblk0: mmc0:1234 SA04G 3.63 GiB

would indicate that MMC driver has detected the card and communicated enough to get identification. The next line should be something like:

[ x.xxxxxx] mmcblk0: p1 p2 p3

It appears to be hanging reading out the partition table.

I think it would be easier to debug the SD problems while in NAND boot. At least the system isn't hung. From the sounds of it, the SD card can't mount.

Eason, what happens with the mount? Any messages? Is the card inserted after NAND boot? If it's a custom board, maybe one of the upper data lines is not connected properly.

Hi Miroslav,

         I have change mmc0_pin_mux :

        {"gpmc_ad13.gpio1_13", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP},

        {"gpmc_ad12.gpio1_12", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP},

        But the problem is still the same :

    So what should I do ? It cant mount filesystem.what is the SD Card the mechanism of mouting filesystem   ?

 Hi  Norman Wong,

    When I insert SD into the board, It  starts from nand. But It would be stuck when detecting SD. I dont know why?

Maybe the same problem with sd startsup.

Not much more to add. I think you'll have to probe out all the MMC/SD lines. The SD Card inteface start up in phases. First low frequency, one-bit data. After some handshaking, high frequency 4-bit data. My guess that it's getting past the first part but the second part is failing. Perhaps a shorted or open DAT line.

Another test would be to NAND boot with no card inserted. After fully booted and logged in, insert a SD Card. If you can probe the SD Card signals as you insert the SD Card. That's all I got. Good luck.
