When you create the GitHub issue please be specific about the exact layout of the setup you have.
It is not fully clear to me if you are connecting the nrf52840_pca10056 to the i.MX6UL via the PCA10056’s USB connector (i.e. using the PCA’s on-board debugger) or directly via lines to the UART from the i.MX’s pins to the nRF52840’s pins without any circuitry.
