Appendix 1 Hardware Designing Guideline
1. Boot Modes
OK1052-C can support different flashing modes and system booting modes, once system powered
or reset, it will select flash and boot mode by reading system booting pins configuration information
When users designing carrier board, we kindly suggest users to design the carrier board with this
circuit.
2. IIC mounted with different slave devices
When IIC mounted with different slave devices, please make sure IIC addresses are not conflict.
3. IIC designed with pull-up resistor
When designing carrier board, pull-up resistor should be added to IIC, otherwise, it may cause IIC
device unavailable. IIC on OK1052-C is pull-up to VCC3V3 by 4.7K resistors.
4. cautions for different devices during debugging
Much sources on carrier board are multiplexed, please check connection status of related jumper
cape or resistor, otherwise, it may cause function unavailable.
