UNIFLASH: is a CP2102 USB-UART cable compatible with this tool?

Part Number: UNIFLASH
Other Parts Discussed in Thread: AWR1843, AWR1843BOOST

Hi, I am trying to flash an awr1843 board with a cable based on CP2102 chip but sometimes I have issues because the tool does not recognize the COM ports or the flashing process gets stuck, and I have read that uniflash supports xds110 or ftdi drivers and in an application notes mention the ftdi too, but in the unifash docs I can´t find this info

    Hello Jairo,

    Please give us some time to look into this. We will get back to you before the end of this week.

    Hello Jairo,

    Ideally external UART emulator should not impact the UniFlash functionality. Dependency of XDS110/FTDI is mainly required for Auto detect feature of UniFlash where it can detect which type of TI device is connected with the system.

    To flash any binary to the device, it requires mainly the UART COM port which can be emulated by any other emulator (UART to USB).

    So with that doesn't it work at all with UniFlash or raises error intermittently?

    error intermittently was at the beginning, now we have put 10K pull ups resistors in the UART lines (according to the awr1843 schematic) and the flashing goes ok but still we have issues loading the config from the GUIs in labs that requires messages interchange between the radar and the matlab script, in labs like SRR I have added the commands to start the GUI in the code like in the MRR lab (    MRR_MSS_CLIAdvancedFrameCfg(1, dummy); and MRR_MSS_CLISensorStart(2, dummy); ), but now we are trying to open the demo visualizer GUI and that code is not like the SRR or MRR, the GUI opens and when we send the configuration sometimes the radar is programmed but sometimes nothing happens, the console messages keeps empty and I thought that the USB-UART cable could be the issue

    Hi Jairo,

    It is very unlikely that it is do with USB-UART interface/connection. 

    As you have modified the source code of SRR with your requirement, first check and confirm that all the commands are reached to the device and applied.

    And make sure that you make equivalent change in GUI as well, if any of above changes impact device data flow or format which GUI recieves.

    I tested the cable with the AWR1843BOOST evk and works
