Overview This document mainly introduces the operation of two factory defaulted evaluation board, that is CMT2380F64-QFN40-Eb and CMT2380F64-QFN48-EB (hereinafter referred to as CMT2380F64-EB). The evaluation platform is designed specifically for users to evaluate the performance of CMT2380F64. As the controller kernel of CMT2380F64 is a CM0 level single chip. This evaluation board can be regarded as its development board for various functions of CMT2380F64 such as debugging, verification and testing.
The following shows introduction to the two evaluation boards. 1.1 CMT2380F64-EB Introduction Top view and introduction of the CMT2380F64-EB is shown in the following figure. 1. SMA Connector 2. J-Link Debug Interface 3.

; [1]. LCD Shiled is a lattice screen shiled with size of 128x64 that can be plugged into the CMT2380F64-EB is a screen with 4 buttons and it can be used as function of human-computer interaction input and display. For the LCD_RESET pin of the shield board is corresponded to the NC pin of CMT2380F64-EB, the LCD_RESET pin of the LCD shield cannot be controlled.

; [1]. LCD Shiled is a lattice screen shiled with size of 128x64 that can be plugged into the CMT2380F64-EB is a screen with 4 buttons and it can be used as function of human-computer interaction input and display. For the LCD_RESET pin of the shield board is corresponded to the PB12 pin of CMT2380F64-QFN48-EB, the LCD screen can be effectively reset by PB12.
A firmware will be pre-burned around the chip before delivery for multiple functional test and evaluation (it needs to be used together with LCD shield display) for CMT2380F64-EB or CMT2380F64-QFN48-EB. This firmware will be updated from time to time as functional changes, it can be downloaded from the official website of HOPE and it will be updated through J-Flash software from J-link debugger (the updated firmware is described in detail in Chapter 4 of this article).
Note The matching parameters of CMT2380F64-EB and CMT2380F64-QFN48-EB are different according to the frequency. For example, CMT2380F64-EB -434MHz indicates that its optimal matching parameter patch component is at 434MHz frequency band; CMT2380F64-EB-868MHz indicates that its optimal matching parameter patch component is at 868MHz frequency band. Thus the accurate transmission power effect can be tested by selecting optimal working frequency band in accordance with the EM.
4 Supplymentary 4.1 Firmware Update Burning Operation Both of CMT2380F64-EB or CMT2380F64-QFN48-EB can be updated via J-Flash. The following will describe how to upgrade the firmware: Start the J-flash software. Take J-Flash V6.30d as an example, as shown in Figure 4-1. Click on "File" in the main menu bar and select "New Project".

Return to the J-Flash window, click "Target" in the main menu bar, select "Connect" and connect the target board (CMT2380F64-EB or CMT2380F64-QFN48-EB) through the J-link debugger. Before this, ensure that the J-link debugger is properly connected to the CMT2380F64-EB or CMT2380F64-QFN48-EB.
AN191 Click "Target" on the main menu bar, select "Manual Programming", and then select "Program", (it is recommended to erase the chip before operation) the J-Flash will burn the target file for CMT2380F64-EB or CMT2380F64-QFN48-EB. Figure 4-7. Manually Burning Operation Figure 4-8.
