make upload results "Bad Command"

[nitimohi]

I am trying to use this package to check if could program the SIM7000,
after struggling for couple of days here there I got everything running but last step :

make upload - Bad Command.

Using:
linux Ubuntu 18.4.1
QMake version 3.1; using QT version 5.11.1 /opt/qt5/lib(i build it)
UPLOAD_DEV=dev/ttyUSB0
ls /dev/ttyUSB* : /devUSB0 /devUSB0 /devUSB1 /devUSB2 /devUSB3 /devUSB4
lsusb : Bus 001 Device 003 ID 1e0e:9001 Qualcomm / Option

copied serial library to project directory
i don't know what else i am missing

Did you build the upload tool ?
Can you post the full console output ?

Make sure you use the correct serial device and retry a couple of times. The make scripts have a upload-retry target that just retries uploading until it works.
