Dear Praveen
Sorry for the delay
AFE44x0SPO2EVM GUI version 2.4
PC details
Hardware detected
Thank you
Hi Manigandan,
The EVM should be recognized as a COM port device and not a HID device.
Do you press the S2 switch while plugging in the USB cable to the EVM? If no, have you updated the EVM firmware?
If no, can you please follow section 6 in the user guide and update the firmware rev 1.4?
The EVM firmware hex fiel can be found in the following folder after you run the firmware executable and install the firmware source to the PC. Here is the link to the FW source code: https://www.ti.com/lit/zip/slac679
The Firmware hex file can be found in the following location: C:\AFE4490EVMFWSRC-v1.4\AFE4490EVM_FW_SRC_v1.4_Release\Firmware_Updater
Once the firmware is updated and the USB to the EVM is reinserted, Win10 pc will recognize the hardware as a USB Serial Device and the device manager should look like in the image below (pls note the com port number may be different).
