Hello Chenjinghall,

Have you been using your buggy fine up until now or is this a brand new buggy and you are unable to load programs onto it via the usb?

If you are a new user to the buggy then you may not know that when loading a program into the buggy via Flowcode it will prompt you to press the reset button on the device, therefore allowing it to go into "Program Mode" which will then allow data to be written to the device. This is due to the bootloader inside the buggy only activating program mode when the reset button is pressed.

If you are aware of this fact and have programmed the buggy fine before hand and the chip containing the bootloader is not working properly, then you can purchase a chip with the firmware preloaded onto it from us. if you email sales <@> matrixmultimedia.co.uk for more information on this.

You can test whether the buggy is working by trying to use the buggy programmer that comes with Flowcode, or is available in our resource centre here.

If you have taken the chip out and reprogrammed, then you have removed the bootloader and you'll need a new chip.

We can post a replacement chip to you. This will cost you £10 (for postage to the UK) or £15 (everywhere else). I believe that you are already in contact with my colleague, Jayne. Please contact her to arrange the payment.
