The current version of the development board is 2.0. According to official guidelines, the latest NFC Cockpit has been downloaded and the VCOM driver has been manually successfully installed. After physically connecting to the PC through USB, two USB serial devices (CO8M&COM9 corresponding to SPI protocol) are displayed in the COM of the device manager, but the VCOM for nxp is not displayed. After opening Cockpit, it also displays disconnected. Therefore, it is speculated that the firmware version of the LPC1769 on board is too old? But according to the manual, when you first enter Cockpit, you will be prompted to update the version? (Actually, there is no prompt) At the same time, the official guidelines say that after the SW200 is disconnected, it should enter the mode of a large capacity USB device (these two switches are not soldered onto the board), but in reality, the PC cannot recognize this device? That's the current situation。
目前开发板班的版本为2.0，根据官方指引，下载了最新的NFC Cockpit，并且手动成功安装了VCOM驱动，通过USB物理连接到PC之后，在设备管理器的COM显示了两个USB串行设备（CO8M&COM9对应SPI协议），但是没有显示nxp的VCOM，打开Cockpit后也是显示disconnected，于是猜想可能是板载的LPC1769的固件版本太老了？但是根据手册首次进入Cockpit时后会提示更新版本？（实际上没有提示）同时官方指引上说SW200断开后，就应该进入大容量USB设备的模式（本身板子上就没有焊接这两个开关），但实际时PC识别不到这个设备？目前情况就是这样
