Hi

I'm new to Cypress. I'm using the CYBT-2130430-Mesh evaluation kit for the first time. When run fw-loader I get the error "No connected devices" (info below).  I also get the "Serial port not detected" error when I tr to build/program.  I have the device connected via the micro USB connector (J6).  The LED 1 blinks red, green and blue. The other two lights are green. Is there something I should have done to enable the USB connectivity? I have tried this with two boards and I'm getting the same result. I'm running Ubuntu Linux 18.04.2. LTS.  Thanks in advance for your help.

$ ./fw-loader --device-list

Hi PeAt_4325526,

  • You do not have to use fw-loader to download firmware to CYBT-2130430-Mesh.
  • If you see an error as "Serial port not detected", your device bootloader is not listening on the WICED HCI UART. So please do the below steps to help the chip to starts the bootloader instead of the main application. Then try to build and download the application from the ModesToolBox IDE. If you do not specify the port of your device, modus will automatically select one of the device connected to your PC.

Steps:

  • Press and hold the 'Recover' button on the kit.
  • Press and hold the 'Reset' button on the kit.
  • Release the 'Reset' button.
  • After one second, release the 'Recover' button.

Could you please try and please let me know the result.

Thanks,

-Dheeraj
