My setup is extremely simple, I have a device that takes usb-c power and outputs serial data at 3.0v. I am connecting both the OLA board and my device to the same power source (shared ground) via usb-c cables and then running a jumper cable between the tx line on my device and the rx pin on the OLA. I have configured both of the devices to operate at 500,000 baud. I have also updated the OLA to the latest available firmware and confirmed that enableSD=1 and logSerial=1. All other logging is disabled.
I have confirmed that 3v of serial data is coming across the tx line, but when I power them both on I have had very limited success getting the OLA to log the data. When I press the reset button to wake it from deep sleep, I see the stat light blinking rapidly indicating that something is writing to the SD card. When I power down the device and remove that card, the serialLog file is 0KB most of the time. I have gotten it to work a few times, and validated that the data is correct, but I can't consistently repeat whatever it is I am doing.
Any help will be greatly appreciated!
