I seem to have an error installing the firmware, the APM planner recognizes the board via USBModem1 and when I look at output logs it starts and finishes downloading. Sometimes it will have trouble flashing the board and sometimes it will simply hang in limbo with “Parameters downloaded 0/?”. The 3DR radio connects fine, and it seems like the APM planner is recognizing the board. Not sure what to do. Any help is much appreciated. Thanks.
Let me see if I understand this, you have two issues. The first, is that you are unable to flash the board, but only sometimes? Does this mean you got it to successfully flash? The second being that it sometimes is unable to connect, again, does this mean that it sometimes works?
Can you post log files for some of the failures?
As per viewtopic.php?f=82&t=5035 can you please post what version and operating system you’re using, as well as which firmware version you are using?
