AWR1642BOOST: Error when trying to use flash programming command line utility

Hi,

my customer is looking for a command line flash programming utility that allows automated and remote programming of QSPI flash on AWR1642BOOST. When trying to use "mmwaveprog_cmdline.exe" that comes along with device firmware package, following error was displayed:

=======mmWave Flash Programmer 01.01.00.00=======

  File "mmwaveprog.pyc", line 212, in _send_start_download
KeyError: 'META_IMAGE1'

The used batch file and the command line is shown here.

Batch file:

FORMAT,SFLASH
C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr16xx\mmw\xwr16xx_mmw_demo.bin,META_IMAGE1,SFLASH

Command line:

mmwaveprog_cmdline.exe -c -p 16 -b awr1642_mmw_demo_batch.txt

What is the reason for above error and how can it be avoided? Note that Uniflash is not an adequate workaround, or can Uniflash be also invoked via command line?

Thanks,

Peter.
