Other Parts Discussed in Thread: MMWAVEICBOOST
Hello Guys
In the previous question, I posted a question about the board circuit configuration.
(Link : https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1249506/iwr6843aop-i-can-t-connect-6843aop-and-xds110-10pin/4726950?focus=true)
By changing the circuit through the answer, the operation such as binary download to the board was confirmed.
It really helped me a lot.
But while I was testing my board, I had a few questions.
As shown in the picture below, the SOP circuit is composed.
It was confirmed that the download was normally performed in Flashing mode, the same as the SOP configuration confirmed in the USER guide.
Afterwards, after configuring SOP called MMWAVEICBOOST Mode, JTAG connection was attempted, but there was a problem of not being able to connect.
((In EVM, JTAG is normally connected in that mode, Via MMWAVEICBOOST's 14 PIN JTAG jumper.)
However, strangely, JTAG connection is made in Functional SOP configuration, and it was confirmed that JTAG connection is made even when both switches of SOP0 and SOP2 are turned ON.
Shouldn't JTAG connection only be possible in the SOP configuration of MMWAVEICBOOST Mode?
Is JTAG connection possible with the above two SOP configurations?
Also, for boards that have never been downloaded, the provided examples could not be downloaded to the board through the JTAG connection.
However, after downloading to the board through the Flashing mode and RS232 even once, I was able to download the examples provided to the board through the JTAG connection.
In order to download and debug the currently provided examples through JTAG, do I have to download through Flashing mode at least once?
Or does my board need fixing?
I am looking forward to your reply. thank you
