hi dear robert i am farahani we designed new pcb with base "begaleboneblack" siatara am3358 i run kernel version 3.8.x bone 80 bone 80 need for rtl8732 wifi i run lcd 4.3" for 4dsystem company and run .dtbo " BB-BONE-LCD4-01-00A1" when use cat /sys/devices/bone_capemgr*/slots *run config file or dtbo in eeprom when startup.* *and run , no problom,* *in the my pcb place aic codec and run with *echo BB-BONE-AUDI-02 > /sys/devices/bone_capemgr*/slots *run cound card and no problem.* *when i use both.mean lcd with audio renamue *BB-BONE-AUDI-02-00A0.DTS TO BB-BONE-AUDI-03-00A0.DTS AND
dtc -O dtb -o BB-BONE-AUDI-03-00A0.dtbo -b 0 -@ BB-BONE-AUDI-03-00A0.dts AND MOVE mv BB-BONE-AUDI-02-00A0.dtbo /lib/firmware AND echo BB-BONE-AUDI-02 > /sys/devices/bone_capemgr*/slots ADD TO CAPE BUT NOT SOUND WHEN RUN SOUND ????? THIS PROBLEM HAS USE BOTH "LCD AND AUD" *???* On Monday, March 23, 2015 at 7:08:14 AM UTC+3:30, RobertCNelson wrote: > > The issue is name collision..
