Hi  Mayank,


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.

Hi All,

Here i'm facing the issue even after using the full UART (Tx, Rx, RTS, CTS).
These 4 pins are connected & configured from both (i.MX6UL & nrf52840_pca10056).

Note : nrf52840 chip is flashed with HCI_UART sample app of zephyr. In that i have configured 4 pins and make HWFC enable from nrf5.conf file.

Ans still i'm not facing this issue continuously. Lets say i'm keeping beacon scanning on for 4-5 hours then its working fine. It crashes when i keep it running for 2-3 days.
