Hello, I want to play audio on Beaglebone black so i am using audio cape with TLV320AIC3106 <http://www.ti.com/product/TLV320AIC3106> codec for the same.I am able to load BB-BONE-AUDI-02-00A0.dtbo on 8.7 Debian(4.4 kernel) on Beaglebone Black as shown below. This BB-BONE-AUDI-02-00A0.dtbo file comes by default in the lib/firmware folder. i dint do any modifications in the .dtbo file. 8.7 debian IoT( 4.4.54-ti-r93 kernel):: aplay -l ---> no devices found After changing uEnv.txt (cape_enable=bone_capemgr.enable_partno=BB-BONE-AUDI-02) root@beaglebone:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: B [AudioCape Rev B], device 0: davinci-mcasp.0-tlv320aic3x-hifi tlv320aic3x-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 root@beaglebone:~# dmesg | grep cape [ 0.000000] Kernel command line: console=ttyO0,115200n8 bone_capemgr.enable_partno=BB-BONE-AUDI-02 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait [ 3.640488] bone_capemgr bone_capemgr: Baseboard: 'A335BNLT,00C0,4717BBBK0E43' [ 3.647847] bone_capemgr bone_capemgr: compatible-baseboard=ti,beaglebone-black - #slots=4 [ 3.694039] bone_capemgr bone_capemgr: slot #0: No cape found [ 3.738032] bone_capemgr bone_capemgr: slot #1: No cape found [ 3.782031] bone_capemgr bone_capemgr: slot #2: No cape found [ 3.826031] bone_capemgr bone_capemgr: slot #3: No cape found [ 3.831847] bone_capemgr bone_capemgr: enabled_partno PARTNO 'BB-BONE-AUDI-02' VER 'N/A' PR '0' [ 3.840606] bone_capemgr bone_capemgr: slot #4: override [ 3.845962] bone_capemgr bone_capemgr: Using override eeprom data at slot 4 [ 3.852977] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,BB-BONE-AUDI-02' [ 3.862957] bone_capemgr bone_capemgr: initialized OK.

If yes ,can anyone please share that dts file and also help me with the modifications to be done? I have been stuck with this since a week,please help where am i going wrong.I couldnt find any support for loading audio cape on latest kernel. waiting for your response.
