Firmware Updates for the MP3 Trigger V2

by

If you purchased an MP3 Trigger V2 before May 1, 2010, please update your firmware to version 2.10 below. This update addresses an issue with the serial control port baud rate. Please note that I’ve provided three different downloads: One for the standard serial baud rate of 38.4 kbaud, as well as one each for 9600 baud and 2400 baud.

NOTE: These files are only for MP3 Trigger V2, not for the older original model, which does not require an update.

MP3 Trigger V2 Firmware v2.10 38.4k baud
MP3 Trigger V2 Firmware v2.10 9600 baud
MP3 Trigger V2 Firmware v2.10 2400 baud

Instructions on how to update your V2 firmware are in the datasheet, but here’s a quick review:

1) Download and unzip one of the files above.

2) Copy the resulting hex file to a microSD card and rename it to: “MP3TRIGR.HEX”. It does not need to be the only file on the card – it just needs to have that precise filename.

3) Insert the microSD card into your MP3 Trigger V2 and turn the power on while holding down the center navigation switch.

4) Wait for the Status LED to go solid, then cycle the power. You’re now running the new firmware.

Please refer to the datasheet for a more detailed description of the Status LED indications when running the bootloader.
