We, the undersigned, have joined this petition with the intent of persuading SimpleDevices (owned by Universal Electronics Inc.) and Rockford Corporation to release relevant GPL-protected source code for the Omnifi DMS1 and DMP1 music players. These two companies have jointly developed a terrific product. The user community would like to further improve upon these products by offering even more features. This will in turn help to promote the Omnifi product line and lead to increased sales due to expanded functionality. Browsing online forums and blogs shows that people have started purchasing Omnifi devices exclusively due to the potential functionality provided by current open source software development efforts.

For the enthusiast development community to enable the full potential of Omnifi devices, access to the bootloader is required so that a more full-featured kernel can be loaded. If this bootloader and kernel were completely developed by SimpleDevices using closed-source code, third party enthusiasts would have no option but to develop their own code. However, Omnifi devices use modified versions of GPL-licensed bootloader and kernel.

Bootloader: The ARMBOOT bootloader used by Omnifi devices is GPL-licensed. The code of the ARMBOOT bootloader has been modified to incorporate specific kernel validation techniques. Because the source code of ARMBOOT was directly modified, it must be released to the public under the GPL license.

Kernel: The Linux kernel used by Omnifi devices is GPL-licensed. The code of the Linux kernel has been modified to directly include device drivers. If these device drivers were external modules that were privately coded, they would not have to be released under the GPL license. However, these device drivers are not external modules but rather have been merged with the Linux kernel code. Because of this, the source code of this modified kernel must be released publicly.

At this point in time, both SimpleDevices (Universal Electronics Inc) and Rockford Corporation are not in compliance with the GPL license. SimpleDevices modified two GPL-licensed code sets. SimpleDevices sold this modified, GPL-protected software to Rockford Corporation. Rockford Corporation, in turn, sold this software to the public within the Omnifi DMS1 and DMP1 music players. Because this software is GPL-protected, the modified source code must be released to the public. The original authors of the code released the code for public use with the stipulation that any modifications to the code must also be released publicly. Since this modified code has not been released, both SimpleDevices and Rockford Corporation are not in compliance with copyright laws.
