In my C6747 board , I want boot it with SPI0 flash. I failed.

I describe the question with attachment.

Could you help me?

Thank you so much!c6747boot_question.pdf

    Thanks for describing the details of your problem. Why do you think the boot failed ? You indicate in the document that the LED stays on even when you load the code over the emulator as well as when the application boot from flash.   

    If you suspect that this is a boo tissue then can you perform the following debug steps that will help isolate this issue.

    * Run the debug GEL file provided here when the boot fails and attach the log

    * Reduce to the SPI speed to 10 Mhz and retry the experiment.

    Have you checked the GPIO register to determine that it is set and then unset to blink the LED. Is the timer count setup correctly? If not the LED could be blinking to quickly.

    Regards,

    Rahul

    I do as "Run the debug GEL file", the  log file is shown as the attachment"gel_log.txt".  Does it means anything?

    Thank you very much!

    I have another question, could you help me again?

    From the log it appears, the device is still held inside ROM bootloader and has not exited. The device clocks are setup correctly to 300 MHz but the device seems to be held in the start condition without any error. Have you put a scope on the SPI clk to see if the clock and data transfer starts from flash ? did you try the experiment of slowing down the SPI clock to 10MHz.

    Can you try the SPI boot image on TI evaluation platform before testing it on your custom board.

    You can post all your questions here and we would be glad to help.

    Regards,
    Rahul

    Yes, I  changed the SPI0 CLK to be 10MHz in AISgen. But I set the SPI1 CLK  1MHz in my LED application. May the SPI1 clk affect the SPI0 flash boot?

    What a pitty, the TI evaluation platform of C6747 is not on my hand. 

    Rahul Prabhu said:

    I put the scope  on tge SPI0 clk, and there is no SPI0 CLK is output. What may be the reason?

    I did not find the codes for SPI0 register settings in spiflash_writer_dsp projection.

    Where is the SPI0 clk frequency set, is it set in AISgen? 

    Thank you so much!

    I read the map file of my LED project.

    I find  the address of  _c_int00 is 0080e080, shown as following:  

     

    And I find the entrypoin in spi_writer_dsp(or AISgen) is 0xc1080000, shown as the following:

    Must both of the address be the same?

    No the entry point of the application and the flash writer doesn`t have to be the same. Can you load your led program into L2 or shared RAM on the chip and see if that makes a difference. We provide a SPI boot example and the steps and code for reference herE:
    processors.wiki.ti.com/.../Boot_Images_for_OMAP-L137

    You can look at the instructions specific to the C6747 EVM for reference to see if you can identify any issues.

    Rahul
