CC3235SF: Flash Programming : USB to Uart

CC3235SF: SLImageCreator will not connect through CLI to CC3235

Part Number: CC3235SF
Other Parts Discussed in Thread: UNIFLASH, , CC3220SF

Hello all,

I'm having difficulty connecting to the cc3235SF through the command line interface.  I am consistently getting a time-out error.  I have been able to connect and program the radio through the Uniflash UI in bootloader mode.  I am connecting directly through a serial port and SOP2 is set high. The reset line is toggled manually.

When I switch to the CLI, I follow the on screen prompts to cycle power.  It will get as far as "Received Storage List", then time-out.  What step am I missing when connecting through the CLI?

    Hi,

    Do you have selected right COM port? In case of XDS110 debugger is used, please check at Windows device manager port with name "XDS110 Class Application/User UART".

    Jan,

    Yes, the same COM port is used in both the Uniflash UI and the CLI.  I'm using a FTDI device at the moment.

    Hi,

    That is weird. I have tested connection with my CC3220SF connected via FT232RL and it worked properly.

    > c:\ti\uniflash_4.6.0\simplelink\imagecreator\bin\SLImageCreator.exe device info --port COM3

    I tested with old version of Uniflash (4.6.0) and SOP mode 1-0-0 (2-1-0).

    Can you check with older Uniflash version like 6.x?

    I'll have to go get an older version and give that a try.

    Access to the other SOP lines was removed.  I only have access to SOP2 for the image upload.

    It wasn't my version of Uniflash that was the problem, it was my serial adapter.  I switch to a different FTDI 3V3 model and the CLI commands began to work.  I can now program an image with the CLI.  Weird but it works.

    Thank you for your help.
