Has anyone ever tried using the mp3 player on the ChibiOS website? I downloaded the project file, uploaded the prebuilt binary to my board, but cannot get any sound out of my board. I got the mp3 files in the root directory of the SD card (1GB card), connected my SD card as described in the main.c comments, and have tried adding 47k pull-up resistors to the data lines but haven't gotten any results.

Here's a link to the website:

In the discussion thread you cited, many posters state that they have it working fine:

Why don't you post in that forum?

What output do you get on the UART?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I did post on that forum first but everyone on this forum seems to respond much faster. I'll check UART tomorrow.

''I'll check UART tomorrow''

I'd have thought that should've been the very first thing to check?!

The author of the software gives you an example to show what to expect:
