Considerations
Considerations for the use of development board:
1.
Handle with care and pay attention to electrostatic protection;
2.
If you use SPMI, set SW2, SW3, SW4, SW5 to JTAG. Download .fs file,
then power off. Set to SPMI, power on again to test and debug;
3.
J2 and J3 on the board are VCCX and VCCIO power selection. You
can select 1.8V or 3.3V.
4.
In the normal use of the development board, it is necessary to switch
all the nine switches of S1 to ON;
5.
When testing the static power consumption, nine switches of the S1
need to be turned off.
