Hi,
I am setting the active balancing "EM1402 and LaunchXL-TMS57004 with BQ75PL455Q1 GUI". I did all modifications as mentioned in document that remove R8 and R9 and connecting to NHET00 and NHET02. I am connecting 11 cells to monitor and for 12V i am using 12V-1A adapter supply instead of 4 cells. I did load example code in LaunchXL-TMS57004 and as i am using single board i changed #define TOTALBOARDS 2 to #define TOTALBOARDS 1 as i am using only 1 EM1402 i do keep the switch at single instead of differential. I am running the code in debugging and trying to start GUI but is giving me error "Uanble to open port" one more thing is when Reset the LaunchXL-TMS57004 i.e. i am detaching the USB cable to laptop and again connecting to LaunchXL-TMS57004 LED glows for a second and then goes off.
Another thing is i tried connecting EM1402 directly to GUI using USB to TTL serial cable that time it opens. FYI i am adding one related conversation was going on community and that guy also had the same problem but it didnt solved i guess as that thread communication ended with TI guy advice with check if you have driver for LaunchXL-TMS57004. But FYI i did install driver and i can detect the serial port and i am able to upload code in LaunchXL-TMS57004.
Please help me with this i am trying this for a week. i do made all connections firm and checked the connectivity.
Without LaunchXL-TMS57004 GUI opens. Please please help me sort out the issue
