CMT2390F64-EB Evaluation Board User Guide Overview This document mainly introduces the operation of CMT2390F64-EB. The evaluation platform is designed specifically for users to evaluate the performance of CMT2390F64. As the controller kernel of CMT2390F64 is a CM0 level single chip. This evaluation board can be regarded as its development board for various functions of CMT2390F64 such as debugging, verification and testing.
CMT2390F64-EB can also provide two types of standard single antenna (default) and antenna diversity (one PCB with different BOM, double Layout compatibility) LCD Shiled is plugged into the CMT2390F64-EB. It is used as the man – machine interaction interface for it provides LCD screen and buttons. 1.1 CMT2390F64-EB Introduction Top view and introduction of the CMT2390F64-EB is shown in the following figure.

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 CMT2390F64-EB or CMT2390F64-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).
2ppm configuration. Therefore, when setting the configuration, it is necessary to ensure that the TCXO mode is used in a pair of CMT2390F64-EB, or the frequency deviation between the two EB is very small, otherwise the communication effect will be affected and the performance will be misjudged indirectly.
Note: As mentioned above, the software configuration of DC-DC needs to be consistent with the hardware of CMT2390F64-EB, that is, enable the software configuration, and the jumper selection of EB module needs to be enabled by DC-DC. If the software is disabled, DC-DC of the EB module turns off.
4 Supplymentary 4.1 Firmware Update Burning Operation CMT2390F64-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".
