Hi

I am using omap 3730 with u-boot 2008.11 and x-loader 1.42,  after x-loader up comes it stops the booting  at  "Starting OS Bootloader..." and hangs forever

If it is booted again by giveing power cycle it come up as below.

Texas Instruments X-Loader 1.42
Starting X-loader on MMC
Reading boot sector

1067372 Bytes Read from MMC
Starting OS Bootloader from MMC...
Starting OS Bootloader...
No OOB scheme defined for oobsize 0
OneNAND:  0 kB
256 MiB


U-Boot 2008.10 (Nov  3 2009 - 19:15:10)

OMAP35X-Family-GP rev 2, CPU-OPP2 L3-165MHz
OMAP3 EVM board + LPDDR/NAND
In:    serial
Out:   serial
Err:   serial
Hit any key to stop autoboot:  0
OMAP3_EVM #
OMAP3_EVM #

the same set of package we used withh 3530 and we were able t boot without any issue. the only change we made with respect to 35xx , in 37xx is we chaged the DPLL4 M, N values.

What may  be the possible resaon for thsi hanging?

 

Thanks

Jitendra

    Jitendra,

    I am see that you are using OMAP3EVM.

    There are many changes in the u-boot and kernel. Assuming that you have already reviewed changes in DPLL4, M and N values; you need to look at this patch posted on the u-boot list:

    http://www.mail-archive.com/u-boot@lists.denx.de/msg28269.html

    There is similar code in x-loader as well. You would need to make similar changes in x-loader as well.

     

    PS: Can you provide the serial# of the EVM main-board and processor module(s)?

    Best regards,
    Sanjeev
