EM7180_set_WS_params() hangs at check parameter acknowledge register loop

Hello! I had this running on the Teensy with no problem, but recently compiled for a SAMD Cortex M0+ board (Seeeduino Xiao), and the function EM7180_set_WS_params() now does not come out of this loop:

    while (!(STAT == param))
{
    STAT = readByte(EM7180_ADDRESS, EM7180_ParamAcknowledge);
}

Maybe I need to change something to work better with my board, but is this perhaps a communication issue between the Sentral and the EEPROM device?

Yes I do. I get all of the normal ...Hold up- suddenly it works and I didn't change anything. Perhaps just a fluke.

It got through the loop but it appears it did not load the WS parameters correctly. Hardware output is working but yaw is way off. Software outputs are unchanging at (declination), 0.00, 0.00

Not sure, but I think my I2C connection is fine. Sorry to be a bother. Here's my debug outputs (I've been shuffling things around for my purposes)

I'll try to just recalibrate. I did move it over a couple spots on the breadboard, and I noticed this thing is quite sensitive to surroundings. Very awesome work, Kris. I'm blown away after struggling with the BNO055. I would love to ask you a few random questions via email if possible. I have a project that I-m going to be taking into limited production, likely in the thousands. All open-source hardware and firmware.
