C6748 boot from nor flash problem

Other Parts Discussed in Thread: TMS320C6748, OMAP-L138

Hi,all
   I want to boot the C6478 from 16 bits parallel Nor Flash(not spi flash), But there are some problems.
   The program is led_pb,and it run well in emulation mode.
   I did it as follows:(from spraat2c.pdf: Using the TMS320C6748/C6746/C6742 Bootloader)
   1、Use Aisgen for D800K006 tool to generate the boot scripts AisLed.bin, the configation:

         

       

       
   Because the led_pb project does not use DDR2, so I do not config it.
   2、write the AisLed.bin to nor flash by the spiflash project(I have already modified the spi flash driver to nor flash driver, and I test it well).
   3、change the bootmode pins to nor flash.
   while it did not boot................., who can give me some advice?
   And also I have some questions:
   first, is there a ccs project or a tool to write the xxx.bin to the norfalsh(not spi flash)? i do not known whether the start address between spiflash and parallel flash the xxx.bin write to is the same.
   second,does the PSC must be configed?,in my opition,it does not must.Because the DSP core and the EMIFA is active at power on, right?

   Please help me, regards

  • Dear qbliu,

    There is a CCS Parallel NOR application under OMAP-L138_FlashAndBootUtils_2_40\OMAP-L138\CCS.

    How did you modify the spiflash project to work with Parallel NOR? Can you share it?

    Thanks,

    Avi Tal.

  • second,does the PSC must be configed?,in my opition,it does not must.Because the DSP core and the EMIFA is active at power on, right?

    PSC is not must for simple LED application.
    Have you configured the PLL properly and PINXMUX in AISgen ?


    first, is there a ccs project or a tool to write the xxx.bin to the norfalsh(not spi flash)? i do not known whether the start address between spiflash and parallel flash the xxx.bin write to is the same.

    As Avi Tal said, we have CCS project for writing binaries into NOR flash.
    C:\ti\OMAP-L138_FlashAndBootUtils_2.40\OMAP-L138\CCS\NORWriter

    Also we have SFH tool to flash the binaries.

    You can also try the LED example in the below TI wiki which has AIS configuration for NOR,NAND and UART boot.
