TMS320F28335 flash programming by SDflash via SCIA - fail to talk to target.

Other Parts Discussed in Thread: TMS320F28335

I want to load my code into TMS320F28335 on-chip flash by using SDflash via the serail port (SCIA).

I set the boot mode 1110 --- boot from serial SCIA.

When I run the SDflash to try to load the code onto flash, the following messages returned on the SDfalsh window:

MSG: Connecting to target

ERR: Failed connecting to the target.

What might cause the DSP not to respond to the SDfalsh?

I have done this on the demo board (eZDSP board from Spectrum Digital) without any problem. I don't know why I cannot do it on my target.

Does any body have any ideas?

    Kamal, you can use C2PROG for SCI based programming.

    Hi Gautam,

    I have the program and I am using the evaluation kit, but  I am getting the following message when I try to load the program.

    *** PLEASE RESET TARGET IN SCI BOOT-LOADER MODE ***

    Connecting with target (autobaud)...  failed (no response)!

    Kamal,

    Here are my suggestions for your problem:-

    1) Please try connecting the device through CCS and check whether you are able to erase / program flash. If everything works successfully this rules out flash issue

    2) Did you try running toggle test to confirm flash algorithms are configured properly on your board?

    3) Have you configured Mode E (SCI-A boot) on your system to use SCI-A boot?

    4) Are you providing 30 MHz input clock to DSP?

    For more details refer to SDFlash_Serial_RefGuide_v3_3.pdf available in <CCS_INSTALL>\specdig\sdflash\myprojects\sdf28xx_v3_3_serial

    Regards,
    Manoj
