Hardware Setup of IWR6843ISK/ODS for Flashing Mode
===========
This guide is intended for users with an **IWR6843ISK and IWR6843ISK-ODS** (EVM).
The guide will walk through setting up the board into **Flashing Mode** as a standalone EVM.
NOTE: The [MMWAVEICBOOST Carrier Board](http://www.ti.com/tool/MMWAVEICBOOST) is **NOT** necessary to flash the IWR6843ISK Rev.C and IWR6843ISK-ODS Rev.B.
If desired, these modules can be used as an antenna module board with the MMWAVEICBOOST.
See [Hardware Setup for Flashing in MMWAVEICBOOST Mode](../../../common/docs/hardware_setup/hw_setup_mmwaveicboost_mode_flashing.html)

# 1. Configure IWR6843ISK/ODS
To use the IWR6843ISK/ODS in standalone mode (without MMWAVEICBOOST) the switches on the front need to be set as shown:
### Front of IWR6843ISK/ODS
# 2. Connect micro-USB
Connect the micro-USB cable to the EVM at the connector shown and then to a PC.
Note that a separate power supply is not needed as the IWR6843AOPEVM gets power from the USB connection itself.
LEDs on the EVM should turn on.
# 3. Set SOP Mode for Functional Mode
Ensure functional mode is enabled by setting the SOP switch on the back as shown below.
### Functional Mode
| S1.1 | S1.2 | S1.3 | S1.4 | S1.5 | S1.6
-----------------------|------|------|------|------|------|------
S1 switch settings | Off | Off | On | On | Off | N/A
# 4. Toggle RST switch
To ensure that the correct SOP mode is latched once power has been applied, power cycle and then press and release the RST switch identified below. The green LED near S3 should toggle OFF and ON when the switch is depressed then released.
[[y! Toggling NRST
After any SOP mode change, RST should be always be toggled to ensure a reliable boot-up state.

Next Step
===========
Now that the hardware has been setup for **Flashing Mode**, go to the software guide for [Using UniFlash with mmWave](../software_setup/using_uniflash_with_mmwave.html).
