BOOT from NAND FLASH with TMDXEVM6678L EVM

Hi,

The gel file i2cConfig.gel is needed to change the IBL boot params table stored in EEPROM 0x51 address directory and it works along with i2cparam_c661x_le.out executable. The idea is param table can be changed to the settings as per the gel file settings by executing i2cparam_c661x_le.out program.

You can refer to "Loading and Setting up the EVM with the Gel file" section of the BIOS MCSDK user guide which describes an example gel file to load on to the EVM . http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_Getting_Started_Guide#Use_JTAG_to_Load_the_Application . Similar method can be used to load the i2cConfig.gel file  located under "tools\boot_loader\ibl\src\make\bin\i2cConfig.gel".

-Thanks,

Hi,

finally, I have succeed more easily to change the configuration of the IBL by changing the /ibl/src/util/iblconfig/src/device.c file and compiling the IBL, flashing the EEPROM.
=> No need of the gel file, one less operation with CCV5.

But I didn't succeed to boot from NAND the Hello world example.

I have added traces with "uart_write_string (...)" calls on the iblmain.c and dload.c file:
=> I go to the iblBootElf(...) function from elfwrap.c
=> I go to the DLOAD_load(...) function from dload.c
=> but the (!dload_headers(fd, dyn_module)) returns FALSE.

=> I suppose that THE HELLO WORLD flashing in the NAND FLASH is not at the right place or not at the right format  ?
I have followed the example : 
- Copying the .out into app.bin.
- loading the file on 0x80000000 DDR2 memory adresse.

As the .map file of the Hello world example give the memory for the program to be 0x0082000 :

  OUTPUT FILE NAME:   <../bin/i2cnandboot_evm6678l.out>
  ENTRY POINT SYMBOL: "_c_int00"  address: 0086cda0

  MEMORY CONFIGURATION

     name            origin    length      used     unused   attr    fill
  ----------------------  --------  ---------  --------  --------  ----  --------
    L2SRAM                00820000   000e0000  000573b6  00088c4a  RW X
    L1PSRAM               00e00000   00007fff  00000000  00007fff  RW X
    L1DSRAM               00f00000   00007fff  00000000  00007fff  RW X
    MSMCSRAM              0c000000   00200000  00000000  00200000  RW X
    DDR3                  80000000   10000000  00000000  10000000  RW X

, I put this value in the nand_writer_input.txt file :

 file_name  = app.bin
 start_addr = 8519680

The Nand Writer help file refers to a start_addr 16384. What is the right value ?

Does somebody really try this example with the EVM 6678 ?

Hi,

Good to hear that your problem is resolved.

regarding the change of i2cparams there are multiple ways.

1. change the device.c source file itself and rebuild IBL (like you did here, you need to have the IBL build environment).

2. Use the i2cConfig.gel along with a DSP executable (Advantage is you don't need IBL build environment and the change happens in the target itself).

3. We would be providing a configuration tool which would change the configuration parameters of the ibl image (either released/rebuilt). Later you can use the program_evm script to flash the image to eeprom 0x51. (Currently release 2.0.5 has an issue, where this tool is not prebuilt).

Hello GAUTHIER Jean-Michel,

I was trying to work the same in windows environment. I have provided the screen shot of the output here.

My boot switch are 

Switch   1   2   3   4   

sw3      off off on off

sw4       off off on on        (if i change this setting to  on off on on, as provided in the readme.txt, then no output).

sw5       on on on off 

sw6       on on on on

Since you have already tried this and succeed, kindly provide me with some inputs.
