Hello,
We are facing issue, when we power qca4020 device it is going in Diagnostics mode. As we can see in device manager
Qualcomm HS-USB Diagnostics 9055 (COM72)
1) What is the reason of the qca4020 board going in diagnostics mode?
Thank you,

This is because you have the manufacturing image inside the QCA4020 board.
This image is needed for connecting with the QDART or the mfg_tool.exe
If you erase the flash, the board will go back to normal.
We are not able to erase the flash, using below command
qflash.py --erase --comm 79
When we enter this command the output stuck at qflash.py Info: Download device programmer...
Is there any other way to erase the flash?
Thank you,
Akshaay
Issue Solved !!!!
We were using 10k resistor as pullup on gpio 22 to connect it in EDL mode.
On using 1k resister insted of 10k solved it.
