DM3730 Initialization and Boot Configuration issue

Venkataraman Gunasekaran

Other Parts Discussed in Thread: DM3730

Hi,

I am right now using the DM3730 processor, please let me know whether there will have any boot code available in the board in production units? if not is there any provision to load the boot code to the processor in baseboard? The minimum boot code is required in the processor to load the boot loader and the OS images from SD card or USB.

Please let me know how to configure the boot code for the production untis. whether I need to configure through hardware settings by manually or it is already set? Also please let me know what is that ROM Code? this ROM code is available already in all the processor board or the user needs to load it?

Regards,
Venkat

    Venkat:

    There is a three-stage boot process;

    1) ROM Boot loader boots system according to the SYSBOOT settings at end of reset.  The boot can be via a memory device such as

        MMCSD, NAND or NOR flash or it can be via peripheral boot , such as USB, EMAC or UART.  This stage copies the x-loader program

       to internal RAM.

    2) x-loader initializes clocking and SDRAM interface  copies the u-boot program to SDRAM and jumps to it.

    3) U-boot loads the Linux kernel, passes the stored u-boot parameters and starts the Linux kernel.
