How many different way are there to load the Kernel and File System file in AM1808 ?

  1. Using Ethernet Cable
  2. Using UART
  3. ... ?

    Hi,

    I've read the Boot loader procedure using the UART boot Master, but i can't find the way to load Kernel in this document ? I can understand now how to create a AIS image, but i am not sure if is it correct or not !! Because every time i Load the AIS image file using UART HOST v1.3, the I/o Read error occurs.

    What things should i keep in mind while creating the AIS image ? Below are the settings i've set to generate AIS image

    I've set the

    1. Pin Mux Settings using Pin Setup Utility    
    2. PPL 0, PPL 1 Settings
      1. PPL 0:                                                                                              
        ARM9_0: GEL Output: |              PLL0 Information             |
        ARM9_0: GEL Output: ---------------------------------------------
        ARM9_0: GEL Output:
        ARM9_0: GEL Output: PLL0_SYSCLK1 = 24 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK2 = 12 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK3 = 8 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK4 = 6 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK5 = 8 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK6 = 24 MHz
        ARM9_0: GEL Output: PLL0_SYSCLK7 = 4 MHz
        ARM9_0: GEL Output:
      2. PPL 1:                                                                               
        ARM9_0: GEL Output: ---------------------------------------------
        ARM9_0: GEL Output: |              PLL1 Information             |
        ARM9_0: GEL Output: ---------------------------------------------
        ARM9_0: GEL Output:
        ARM9_0: GEL Output: PLL1_SYSCLK1 = 24 MHz
        ARM9_0: GEL Output: PLL1_SYSCLK2 = 24 MHz
        ARM9_0: GEL Output: PLL1_SYSCLK3 = 24 MHz
    3. PSC Settings                          

    I am not sure about the following settings

    1. How to set DDR2 Setting                                               
    2. Flash Setting                                             

    I suppose that i've to change the settings specific to my board setting ? but where can i find this information ?

    Hi,

    For u-boot,

    You need to convert the u-boot.bin to u-boot.ais (input file(ARM application file) as u-boot.bin)

    You need to mention DDR2 timing parameters and booting type and that parameters if NAND/SPI While you are creating AIS.

    After that write the u-boot.ais file into NAND/SPI/NOR which you configured as booting type while you are converting to AIS.
