About

s1giveio is a LGPL licensed, win32 cli tool to analyze/debug the s1mp3 player's hardware.

It's possible that it may look familiar to you, since it's designed like the traditional MS-DOS "debug"-console.

NOTE: There is a new debug console available which offers much more functionality, but requires you to attach a hardware debug interface: S1debug

Features:

real time access to the players hardware (ROMs, displays, flash chips, radio controller, ...)
upload and execution of files with the possibillity to return to the console (if the executed code returns)
reading/writing from/to memory addresses or ports
disassembling of memory

Run it

Follow these steps if you haven't installed the "Swan ADFU driver" (libusb) yet:

connect your player to the pc and bring it into firmware-update-mode. either by choosing this option from inside the configuration menu, or by shorten the right pins of the flash chip
if it asks for some driver, go to step 3. otherwise open the device manager window, choose the adfu driver from the usb device list and select driver update. tell windows you will manually select the driver.
browse to the driver folder inside the s1giveio zip-file and select the inf file.
verify the new "Swan ADFU driver" (usblib driver) has been loaded (maybe you have to turn off and repeat step 1)
have fun with s1giveio
