Issue with DA14531 Integration on RZG3S – Firmware Loading Timeout

Question

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.

Hi Nitish, Normally, you should find BLE firmware under /lib/firmware/renesas/hci_531.bin . Did you follow the instructions included in the Readme file ? You need to extract the meta-da16600.tar.gz file to your Yocto directory (with the other meta layers). Kind Regards.
