Trying to use the OLA board without IMU to log serial data from a board sending out 9600bps. About 50% of the time OLA gives me this message on the USB terminal on reset and sometimes while logging:

The logger recovers after a few additional resets, but not consistent, sometimes it may recover after a single reset, sometimes it may take as many as 5. The logger works the other 50% or so times and without the serial connection attached works 100% with logging RTC data (no IMU) to files on SD card. Everything is 3.3V, 16GB SunDisk Ultra class 10 SD card. Pin 32 is activated to put OLA to sleep, that works, reset works to wake up the logger, but that is when I get the error above on wake from a reset and apparently when connected to serial data. OLA FW version is 2.4, units purchased on 2-14-24.
Any suggestions?
Thanks
