OCTVO-3P-AM335X: boot from NAND I2C,boot device 6

xinjie guo
Prodigy 180 points
Part Number: OCTVO-3P-AM335X

Our AM335x's sysboot[4:0] is set to 10011b.

When the power is repeatedly turned off and powered on, there will be occasional start-up from NANDI2C.The debug  information shows boot device 6. The information as follow:

I measured the level of each pin of the sysboot with an oscilloscope, and it was all in line with the set value.

What will cause the system to boot from NANDI2C？

The system has printed the SPL information, does it mean that the NAND has been correctly recognized，Just failed when reading boot information from NAND？

    Hello,
    SYSBOOT[4:0]=10011b => NAND NANDI2C MMC0 UART0

    1/. From "26.1.8.4 NAND" in AM335x TRM
    "Reading NAND Geometry From I2C EEPROM
    ROM supports a special boot mode called NANDI2C to support NAND devices whose geometry cannot be
    detected by the ROM automatically using methods described in the previous section. If this boot mode is
    selected, the ROM code tries to read NAND geometry from an I2C EEPROM. If the read is successful,
    ROM code then proceeds to next steps of NAND boot, beginning with reading bad blocks information."

    2/.

    Hi

    There is only a 1 in 1,000 probability of getting into NANDI2C launch.If there is no NANDI2C used in the boot sequence, it will start normally no matter how many times it is started.

    So I wonder if booting from NANDI2C is because I can't read whatconfiguration from NAND?

    If NAND is not recognized, then why is SPL still being enforced？

    For SYSBOOT[4:0]=10011b, ROM boot media falls through to NANDI2C when NAND geometry is not recognizable by ROM.

    Since the SPL has already been implemented, can it be assumed that the NAND has been correctly recognized?

    If I set the boot suquence to SYSBOOT[4:0]=01011b,or any other sequences that only include NAND but don't include NANDI2C,then AM335X can boot normally everytime. How to explain this?

    Is the SPL stored in NAND?If so,when it shows SPL information in debug ,can I say the NAND has been recognized correctly?

    Yes, SPL is in NAND, and yes, SPL boots from NAND successfully.

    If so，does it mean the sysboot[4:0] is recognized correctly,and the boot device is NAND? Then why the debug information shows boot device is NANDI2C?

    I thought SPL prints something like "Trying to boot from NAND" for most of time. Then

    Then why it can't boot from NAND sometimes?I mean it has read the SPL in NAND,I think the CPU can commuicate with NAND correctly。Then why it can't find boot image in NAND? What impacts it ?

    Can we add some debug information to the code to see what is affecting the boot sequence？

    Hello,
    Will you share full boot logs as attachments starting from HW RESET for "booting" and "non-booting" cases?

    Hi 

    The "booting" and "non-booting" logs are as follow.

    When it can't boot from NAND,it will show  "SPL: Un-supported Boot Device - 6!!!".

    Hello,
    - From the "booting" log, NAND boot looks fine.
    - From the "non-booting" log, ROM loading/booting SPL looks ok, but from "NANDI2C" boot mode, which is listed as unsupported boot mode by SPL as shown in the log "SPL: Un-supported Boot Device - 6!!!". This could be caused by HW etc... It is possible to modify SPL code to treat "NANDI2C" as normal NAND boot mode, but you'll be on your own to try it out as the SDK you're using is from 2011...
    Best,

    What will cause this?Can you enumerate the possible options？

    Hong Guan64 said:

    Actually we did so,and it can boot from NAND.But we still want to know what will cause this .

    And we ran into another problem,the debug information shows CCC,that means the CPU can't find any boot device .We measure the sysboot[4:0] pin when it print CCC,and it is right.So，another question，what will cause this ?Tthe CPU issue or what other?

    Hello,
    As noted in my previous reply, the issue looks to me related with the HW board.
    Let me loop in my colleague for his input.

    It appears the SPL is read by the NAND, and then the failures occurs.  This means that the ROM is reading the NAND correctly, but something goes wrong when the NAND is read in SPL. 

    -Does this happen on multiple boards?

    -can you send schematic of the NAND portion interfacing with the processor?

    -did you change the NAND driver in SPL in any way?

    Regards,

    James

    Hi,

    We didn‘t modify the NAND driver in the SPL

    Analyze from the source code below arch/arm/cpu/armv7/omap-common/spl.c

    void board_init_r(gd_t *id, ulong dummy)
{
u32 boot_device;
debug(">>spl:board_init_r()\n");

timer_init();
i2c_init(CONFIG_SYS_I2C_SPEED, CONFIG_SYS_I2C_SLAVE);

#ifdef CONFIG_SPL_BOARD_INIT
spl_board_init();
#endif

boot_device = omap_boot_device();

    arch/arm/cpu/armv7/ti81xx/board.c 

    u32 omap_boot_device(void)
{
        return ti81xx_boot_device;
}

    arch/arm/cpu/armv7/ti81xx/lowlevel_init.S

    #ifdef CONFIG_SPL_BUILD
        ldr     r4, =ti81xx_boot_device
        ldr     r5, [r0, #BOOT_DEVICE_OFFSET]
        and     r5, r5, #BOOT_DEVICE_MASK
        str     r5, [r4]
#endif

    boot_device = 6 is from rom register ro，so why SPL is read by the NAND，However, the ROM conducts the wrong value to boot_device

    Based on your investigation, it appears SPL is reading the register which latches in the SYSBOOT pins.  Can you add some debug code which dumps the CONTROL_STATUS register at 0x44e10040, before and after the failures?  For some reason, this register seems to be changing.

    Regards,

    James

    I add some debug code to dump the CONTROL_STATUS register at 0x44e10040,here are the results：MMC boot

    boot from nand

    boot from i2cnand

    boot_device 8 is boot from mmc

    boot_deivce 5 is boot from nand

    boot_device 6 is boot from i2cnand， but the value of the CONTROL_STATUS register is same，

    so why the ROM conducts the wrong value to boot_device？

    Looking forward to hearing from you，thank you.
