Hier geht es um meinen BananaPRO, die Entwicklungsumgebung für den E65 Media Center. Hier werden die Anpassungen am Device Tree durchgeführt und die Entwicklung der low-level LKM, die direkt auf I²C aufsetzen und zusätzlich die Audioeinspeisung ins MOST-Netzwerk. Die Videoausgabe ist erstmal uninteressant.

Die Daten sind kein Geheimnis, es handelt sich um eine Allwinner A20 SoC.

SoC Allwinner® A20(sun 7i)
CPU ARM® Cortex™-A7 Dual-Core (ARM v7 instruction set)
GPU Mali400MP2, supporting OpenGL ES 2.0/1.1 (hardware acceleration support)
RAM 1GB DDR3 SDRAM (shared with GPU)
PMU X-Powers AXP209
Storage MicroSD, SATA
NIC Ethernet 10/100/1000MBit (Realtek RTL8211E/D), WLan
