no data captured by minicom (stay in offline) when boot linux from nand on TMS320C6678 Eval board

TMS320C6678 Eval board does not boot linux from nand. I have program the prebuilt linux image to nand using :

$DSS_SCRIPT_DIR/dss.sh program_evm.js evm6678l-le “eeprom51,nand”

and the console output showed it programs successfully:

Reading and verifying block 574 (9388032 bytes of 9437184)
Reading and verifying block 575 (9404416 bytes of 9437184)
Reading and verifying block 576 (9420800 bytes of 9437184)
NAND programming completed successfully
End programming NAND

The problem is: there is no input data in minicom when configured to boot from nand. 

I use RHEL 6.1 as the host. And followed the document and setting looks correctly.

    Hi, Taishan,

    This may be something to do with your host setup. If you have a window machine, you can try if you can see from window console. Otherwise, search on Internet to see if there are any suggestions for minicom not displaying. Thanks!

    Hi Rex,

    I guess the problem is the target configuration file. I followed the set up document. when lunched the ccxml file and try connect to core-0, error:

    Texas Instruments XDS100v1 USB Emulator_0/C66xx_0 (Suspended)    
        0x00834644  (no symbols are defined for 0x00834644)    

    No source available for "0x834644"

    Any step I missed? I ran example sinewave well. Thanks.

    Hi Rex,

    I  don't know the reason for unable launch the target configuration ccxml, I checked the PLL, DD3 memory all initialized correctly.

     

    I fixed the first one: now can boot from nand, minicom output is correctly. it should attach the initialization script to target configuration. Thanks for your reminding.

    Hi, Taishan,

    Do you mean "No source available for ..." is displayed on one of the CCS windows with a click button "View Disassembly" under it? That simply means that CCS can't find any symbols in the executable because it was not compiled in. I am curious about your configuration. Does your C6678 have a XDS560 Mezzanine on it? Because your ccxml configuration is using XDS100v1USB. It is ok if you don't have a Mezzanine. Otherwise, you should use the correct emulator, Blackhawk XDS560v2-USB Messanine Emulator, for the conneciton.
