100 Voltage ID and VDD override
102 T4240 has a VID feature. U-boot reads the VID efuses and adjust the voltage
103 accordingly. The voltage can also be override by command vdd_override. The
106 vdd_override <voltage in mV>, eg. 1050 is for 1.050v.
108 Upon success, the actual voltage will be read back. The value is checked
109 for safety and any invalid value will not adjust the voltage.
111 Another way to override VDD is to use environmental variable, in case of using
112 command is too late for some debugging. The syntax is
114 setenv t4240qds_vdd_mv <voltage in mV>
118 The override voltage takes effect when booting.
120 Note: voltage adjustment needs to be done step by step. Changing voltage too
121 rapidly may cause current surge. The voltage stepping is done by software.
122 Users can set the final voltage directly.
