Flash V1.6 DM3730 Error

Other Parts Discussed in Thread: DM3730

Hi,

 

We're using a DM3730 on a Variscite SOM, and attempting to reflash the EBoot sector to correct some display issues using the Flash Tool v1.06/1.05.  When attempting to erase the EBOOT region, on a Windows 7 machine (running app as admin), the program gives a crash error code of -1073741819 about 3 seconds after reading the asic ID.  On two Windows XP machines, the application crashes alltogether after the same time period.  We've attempted to use a true UART from an older XP machine, as well as FTDI USB serial adapters.  Using the params AM37XX (Hynix), HWECC, ONFI Compliant, 1 bit ECC, Erase Region Offset 0x80000, size: 0x40000.

What are the hardware requirements in order for this to succeed?  The Flash Wiki indicates different switches for different carrier boards, however, would like to know more details on the exact hardware signals and states required, as we don't have schematics for the carrier boards listed, ie: Mistral.  Also, what are the EBoot requirements in order for this to succeed? 

 

Please advise if additional info is needed.  Thanks,

 

Nick

    Nick:

    Could you send text window output from Flash v1.6?   Also, our SOM with Hynix LPDDR/NAND is not ONFI compliant.

    Need to know DDR and NAND part numbers, DDR size and clock freq.

    Regards,

    Hi Michael,

     

    Here is the output from Version 1.6, Win7, USB-Serial:

     

     

    ¯ -stdout

    ¯ -omap 3

    ¯ -no_force_package_alignment

    ¯ -com 25

    ¯ -t 60

    ¯ -p EVM_MDDR_HYNIX_2G

    ¯ -2

    ¯ chip_erase NAND1BITBOOT 40000

    ¯ Leaving parameter file:temp_script.txt

    ¯ @temp_script.txt

    ¯ Looking for device (omap com25)

    ¯ Please turn off device, then turn it on again

    ¯ Awaiting ASIC id

    ¯ AsicId items 04

    ¯ AsicId id 01 05 01 36 30 07 07

    Console program aborted or crashed, exit code: -1073741819

     

    The DDR populated appers to be Samsung K4X1G163PE (x2), so 256MB total.

     

    The NAND populated appears to be Micron NW194. I think this is a 512MB part.

     

    I'll confirm on the NAND since I cannot locate a more specific part number on this part, as well as the DDR speed, which I think is 333MHz. Thanks,

    Hi Michael,

     

    Variscite has confirmed the memory is clocking at 400MHz.  Thanks,

    Hi Michael,

    Just checking if there are any updates to this thread?  I had a lot of posting issues using IE9, not sure if that interrupted this thread.  Thanks,

    Nick
