AMD GeodeTM SP4SC30 to SP4SC31 System Platforms Hardware Changes and Software Compatibility 1.0 Scope This application note discusses the hardware changes and The only potential issues for software applications written the resulting software compatibility implications between for the SP4SC30 platform are those that made use of the the AMD GeodeTM SP4SC30 and SP4SC31 system plat- CompactFlash connector (Change #9), PADCard connec- forms. tor (Change #15), 5V ISA cards (Change #20), or the LM82 temperature sensor (Change #13). However, in all develop- ment work done to date using the SP4SC30 platform, no 2.0 Discussion software developed by AMD has made use of these items, which is why they have been removed or improved on the Table 2-1 lists the hardware changes. The following sub- SP4SC31 platform without causing any known software section describes each hardware change from the incompatibilities. Developers routinely make use of SP4SC30 platform to the SP4SC31 platform and the impli- CompactFlash cards. This is accommodated on the cations of the change on software written for the SP4SC30 SP4SC31 platform by including an IDE to CompactFlash platform. This includes utilization of the additional features adapter card in the kit, with no affect on software. of the SP4SC31 platform by new software, and workarounds for previous applications written for SP4SC30 Furthermore, the SP4SC31 platform offers additional fea- that may be affected by the changes. tures over the SP4SC30 platform, such as TV output, addi- tional sound inputs, and is USB v1.1 compliant. Note: All known software written for the SP4SC30 plat- form is compatible with the SP4SC31 platform. Table 2-1.
