Hello all, I need help to solve a problem. I am using a custom board based on EMX module that have: 4 com port (COM 1=Xbee COM2=IMU at 38400,Com 3 NMEA at 4800 Com4 Octans at 9600. When I am in debug or deployement mode, I put a jumper on the DOWN pin and Xbee is deactivated and debug statements use COM1. CDC is used for GUI on a computer.
My application locks whereas it was working properly few weeks ago. (before switching to 4.2 due to troubles with cdc ewr and so manything…)
After investigating I discovered that the IMU is causing the pb. If I disconnect it application runs fine. When I connect IMU i observe a lot of Buffer OVFLW on COM1 (even if there’s nothing on COM 2 3 and 4…
Do you have any idea?
