**Note:** The steps described in the reference documentation above are the same for both EVK and non-EVK boards, except for the DIP switch position. For the exact DIP switch position required to enable EDL mode on the IQ9075 EVK, refer to the board schematic. Other boards using this SoC may use a different method to enter EDL mode; refer to your board vendor's documentation.
