I did the following: - I fetched https://github.com/beagleboard/bb.org-overlays - copied the file BB-I2C2-RTC-DS1338.dts to BB-I2C2-RTC-DS1307.dts - edited BB-I2C2-RTC-DS1307.dts to refer to my DS1307 chip instead of DS1338 - make src/arm/BB-I2C2-RTC-DS1307.dtbo - sudo cp ./src/arm/BB-I2C2-RTC-DS1307.dtbo /lib/firmware/
I added the following lines to /boot/uEnv.txt: uboot_overlay_addr0=/lib/firmware/BB-UART2-00A0.dtbo uboot_overlay_addr1=/lib/firmware/BB-I2C2-RTC-DS1307.dtbo I rebooted. After rebooting, dmesg shows this: bone_capemgr bone_capemgr: Baseboard: 'A335BNLT,000C,1633BBBG0596' bone_capemgr bone_capemgr: compatible-baseboard=ti,beaglebone-black - #slots=4 bone_capemgr bone_capemgr: slot #0: No cape found bone_capemgr bone_capemgr: slot #1: No cape found bone_capemgr bone_capemgr: slot #2: No cape found bone_capemgr bone_capemgr: slot #3: No cape found bone_capemgr bone_capemgr: initialized OK. I expected to see BB-UART2-00A0.dtbo in slot #1 and BB-I2C2-RTC-DS1307.dtbo in slot #2. The overlays are not loaded. What am I doing wrong? I also expect that loading the overlay BB-I2C2-RTC-DS1307.dtbo will create /dev/rtc1, and also load the module rtc-ds1286.ko. Am I correct in thinking this?
