IWR6843ISK: How to download bin to flash through FTDI RS232 port

Part Number: IWR6843ISK
Other Parts Discussed in Thread: UNIFLASH, , MMWAVEICBOOST

Hi,

I tried on IWR6843ISK+MMWAVEICBOOST board, the binary can be download through xds110 user port with S1 in default mode, I noticed the RS232_TX/RX are also connected to FTDI chip, I changed the S1.5 to OFF, S1.7 to ON, connected the FTDI_USB with micro usb port, 4 USB port can be emulated on PC, choose the 3rd port for flash burn in uniflash tool, but failed.

Switch to use radar studio then RS232 can be connected through FTDI 3rd port, and the BSS/MSS binary can also be downloaded well in radar studio. 

So my question is how to download image in uniflash through the FTDI RS232 port?

    Hello,

    This is not a default supported configuration. However, After switch settings change, nRESET need to be manually need to be applied.
    And boot mode mode configuration need to be correct. Could you please confirm on this?

    Thanks and regards,

    Hi Chethan,

    I pressed the nRST button but still failed. I configured the boot mode in the same way as using XDS110 user port for flash with SOP2/0 mounted, SOP0 unmounted. Any problem?

    Hello Andy,

        I guess you were trying to say SOP1 unmounted instead of SOP0. Please follow following switch settings and I could flash the QSPI flash using uniflash tool. Please see below screenshot.

    Thanks and best regards,

    Chethan,

    Thanks for your try and reply, i tried and it can also work. I compared my switch set, found the cause is S1.11 which should be set as OFF, seems the MCU_SOP0/1/2 status will control the FTDI mode, right? May I know why S1.11 should be set as OFF here? Thanks.

    Andy,

       Yes, you are right!, Not many people notice this. Thank you for your keen observation.

    FTDI also drives the SOP lines through MCU SOP lines  and  it would conflict with on-board jumpers. 

    And MCU_SOPs are the strong driver it overrides the external SOP jumpers and puts the device into incorrect SOP mode, which makes Uniflash not to detect flashing mode of our device. Hence we need to isolate the FTDI driver driving the SOP lines by making  S1.11 to OFF position. 

    Thanks and regards,
