FLASH-PROGRAMMER: FLASH_PROGRAMMER-2 always crashes when trying to open Prolific USB-serial port

Part Number: FLASH-PROGRAMMER
Other Parts Discussed in Thread: CC2640

Hello.

I am trying to connnect the the SmartRF Flash programmer 2 to my CC2640F128 over its UART.  I know the UART connects are good because I can send data to a serial terminal over that connection.

When I try to access the device from the programmer it always crashes when trying to open the prolific COM port  (installs to COM7, shows successfully on device manager).

I tried this with a new (erased) CC2640 as well with no difference, so it looks like there is a problem using the driver? (That seems like the case since the program outright crashes).

See attached screenshot:

1)  Does this app have a problem with the prolific USB-Serial driver?

2) Is there a way to access the bootloader over UART through code composer or other apps?

    Hi,

    1. Are you able to use SmartRF Flash Programmer 2 with another serial port adapter, that is, is this specific to prolific USB-Serial adapter?

    2. Flash Programmer 2 is the only GUI supporting connecting over serial interface. You can of course try the CLI (accessible from the Tools icon in the GUI), but it may suffer from the same issue. 

    There is an application note and application example which you can use as baseline for writing your own application connecting to the device over serial interface. The app note can be found here swra466.
