rsi_bl_waitfor_boardready#

int16_t rsi_bl_waitfor_boardready (void )

This API checks for the readiness of the bootloader to receive the commands from the host.

Returns

• 0 - Success
  

• Negative Value - Failure
  

rsi_bl_select_option#

int16_t rsi_bl_select_option (uint8_t cmd)

Send firmware load request or update default configurations to the module.

Returns

• 0 - Success
  

• Non-Zero Value - Failure (Possible Error Codes - 0xfffffff2, 0xfffffff1, 0xffffffe4)

rsi_get_rom_version#

int32_t rsi_get_rom_version (void )

Get the ROM version of the module.

Returns

• 1 - RSI_ROM_VERSION_1P0
  

• 2 - RSI_ROM_VERSION_1P1

Note

• The return value of this API can be used to infer chip version of the module.
  1 - 1.4EVK
  2 - 1.5EVK

rsi_bl_module_power_cycle#

int16_t rsi_bl_module_power_cycle (void )

Power cycles the module. This API is valid only if there is a power gate, external to the module, which is controlling the power to the module using a GPIO signal of the MCU.
