Initial Power-Up
With all the switches of S1 on the eval board at “off” positions and the external supplies adjusted to 3.7V and 2.5V,
turn both power supplies ‘on’.
Observe that both LEDs (LED1, LED2) are illuminated, see Figure 4.
Confirm DVM#2 indicates 1.6V (+-25mV) for VCore
Confirm DVM#1 indicates 3.7V (+-50mV) this voltage will vary with the load current
Confirm DVM#3 indicates 1.3V (+-25mV) for VPLL
Move DVM#3 (+) lead to TP10 and confirm 1.1V(+-25mV) for VSRAM
