Issue with DA14531 Integration on RZG3S – Firmware Loading Timeout

Hello Renesas Support Team,

I have followed the instructions and successfully added the meta-da16600 recipe to my build, which has included all the necessary patches for integrating the DA14531 with the RZG3S. However, I am encountering an issue and would appreciate your guidance. i have connected using uart interface in scif1 i.e PMOD3A pins i am using RTS and CTS pins also 

When I run the hciconfig command, the output shows the following:

root@smarc-rzg3s:~# hciconfig
hci0: Type: Primary Bus: UART
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
DOWN
RX bytes:0 acl:0 sco:0 events:0 errors:0
TX bytes:4 acl:0 sco:0 commands:1 errors:0

root@smarc-rzg3s:~#
root@smarc-rzg3s:~# hciconfig hci0 up
[ 191.371031] Bluetooth: hci0: Loading renesas/hci_531.bin
[ 196.587731] Bluetooth: hci0: Firmware request timeout
[ 196.592865] Bluetooth: hci0: Continuing despite being unable to load the firmware
Can't init device hci0: Connection timed out (110)

It seems there is an issue with loading the firmware file (hci_531.bin). Could you please advise on the steps to resolve this issue?

Thank you for your assistance.
