LAUNCHXL-CC1312R1: Failed in OAD with python script oad_write_bin.py using offchip image both in server and client

Hi all,

I am trying the OffChip example OAD Server and OAD Client on 2 boards, on which one is acting as concentrator oad server and other is oad client. Followed Readme file in the ti/simplelink_cc13xx_cc26xx_sdk_6_10_00_29/examples/rtos/CC1312R1_LAUNCHXL/easylink/rfWsnConcentratorOadServer/README.md .  All seems good. I am getting the serial messages as mentioned in Readme file on serial port through putty.

But after running python script, you can see the debugging messages which I try to print. Python is blocking on Ser.read as the server is not responding. 

$ python3 oad_write_bin.py /dev/ttyACM0 rfWsnNodeExtFlashOadClient_CC1312R1_LAUNCHXL_app_v2.bin
