Bluno USB port programming issue

There are some points when you fail to upload the Bluno sketch.

1 Check the board selection: Bluno, Bluno nano, Romeo BLE are using ATmega328 microcontroller, so the bootloader is same to Arduino UNO. Bluno Mega1280 = Mega1280 Bluno Mega2560= Mega2560.
2 Disconnect any Serial port device connection. There is only a serial port, so it will be occupied by sketch uploading.
3 Disconnect any wireless connection. Disconnect other bluetooth device connection when you upload the sketch.
4 For Bluno Mega1280, it requires a special driver, plug install the driver first.

Other reasons:

Bluetooth issue: try to upload a new BLE firmware, if you can update the firmware, it means the bluetooth chip is OK.
Bootloader issue: try to upload a new bootloader for ATmega328.

If you find other reason, please supply.

and what might be the reason you guess?

I get Device malfunction warning. The board is not recognized as a USB drive.

I am using Win 7.

I tried again and again always getting Time out warning. My board is recognized as Arduino Uno at COM8.

Have you noticed the computer system requirment. The operation is different if you use win8/7 etc. what's your pc ?

And have you tried to burn firmware again?

I am having problem with Bluno Nano.

I have been doing some work with Bluno Nano and it was working fine until last Thursday. I could not find the right port on Arduino environment. I followed some instruction to upload new BLE firmware by running the Bluno Downloader. I press and hold the boot button when I connect to USB. I get the LED flashing alternately only once in a while. After choosing the right FW and press Upload, I get Time out warning.

Please advice on how to move on.
