I am using the QCA4020 DVK to flash the "Hello World" application to the M20 module. According to the steps here, J31 (or GPIO20_BE as inthe schematic of the DVK) force the DVK into the JTAG mode.
Hello World w/ QCA4020 Dev Kit - Qualcomm Developer Network
My question is that in the QCA4020 or M20 documentations, there is no indication that GPIO20_BE can be used for forcing JTAG mode?. Or may be I am not reading it well in the documentation. Can you please help where in the documentaiton it mention that GPIO20_BE is used for forcing JTAG mode?
Thanks a lot!
