Hi, In the u-boot http://git.denx.de/?p=u-boot.git;a=blob;f=board/ti/am335x/board.c;h=4330be64994dc6cbfaff4b865fee44d82f660a3d;hb=HEAD#l255
there is those lines : 255 <http://git.denx.de/?p=u-boot.git;a=blob;f=board/ti/am335x/board.c;h=4330be64994dc6cbfaff4b865fee44d82f660a3d;hb=HEAD#l255> /* Set DCDC3 (CORE) voltage to 1.125V */ 256 <http://git.denx.de/?p=u-boot.git;a=blob;f=board/ti/am335x/board.c;h=4330be64994dc6cbfaff4b865fee44d82f660a3d;hb=HEAD#l256> if (tps65217_voltage_update(TPS65217_DEFDCDC3, 257 <http://git.denx.de/?p=u-boot.git;a=blob;f=board/ti/am335x/board.c;h=4330be64994dc6cbfaff4b865fee44d82f660a3d;hb=HEAD#l257> TPS65217_DCDC_VOLT_SEL_1125MV)) In the device tree there is those lines : dcdc3_reg: regulator@2 { /* VDD_CORE voltage limits *0.95V -* *1.1V* with +/-4% tolerance */ regulator-name = "vdd_core"; regulator-min-microvolt = <925000>; regulator-max-microvolt = <1150000>; regulator-boot-on; regulator-always-on; }; in the starterware from texas + the patch for the bbb I have nothing concerning the DEFDCD3. And finally in the BBB_SRM you have those lines : The VDD_CORE rail can deliver up to 1.2A at 1.1V. This rail is not accessible for use anywhere else on the board and only connects to the processor. This rail is fixed at 1.1V and is not scaled. So what is the correct configuration for this output ?
