10 1.1 Overview The GM8126 video chip with the FA626TE CPU core provides a high-performance solution to accelerate the image and video related applications, such as H.264, MPEG4, and JPEG. GM8126 supports the JPEG, MPEG4, and H.264 encoders. GM8126 provides a cost-effective and easy-development system for integration and verification of the video application at the early development stage. The GM8126 system platform includes a wide range of basic components, including the H.264 encoder, video capture, display controller, DES/3DES controller, USB 2.0 OTG controller, USB 2.0 PHY, DMA controller, Ethernet MAC controller, Ethernet PHY, Audio codec, and AMBA bus framework, which can reduce the overall system cost.

16 2.1 Description of EVB Connectors Jumper Settings GM8126 contains several jumper settings (JP0 ~ JP7). When the reset signal changes from low to high, GM8126 will latch the logic value of the jumper settings will store specific internal registers. These latched values will affect the behavior of GM8126. For the IPCAM application, the value of JP1 must be logic low. The values of JP2, JP4, JP6, and JP7 must be logic high. As for JP0, it depends on the user application. The definitions of the jumper settings are listed and described in Table 2-1. Table 2-1. Function List of Jumper Settings (JP0 ~ JP7) Pin No. Signal Name Description JP0 (Internal pull-up) PLL1 setting 0:Set PLL1 frequency to 800 MHz 1:Set PLL1 frequency to 400 MHz JP1 (Internal pull-up) PLL32K disabled 0:Disable (Must) 1:Enable JP2 (Internal pull-up) Debug mode 0:Debug mode 1:Normal (Must) JP4 (Internal pull-up) OSC counter 0:Disable 1:Enable (Must) JP6 (Internal pull-up) CPU At-Speed test mode 0:At-Speed test mode 1:Normal (Must) JP7 (Internal pull-up) Firmware update mode 0:Firmware update mode 1:Normal (Must) 8

17 2.1.2 Power Management Setting J27 must be short in order to provide the RTC power. Please refer to Table 2-2 for the definition of the RTC power connector (J27). Table 2-2. RTC Power Connector (J27) Pin No. Signal Name Description 1 ALIVE_3V3 Destination 2 VBAT Source J28 is used to control the wakeup function of the system. If Pin 1 and Pin 2 are short, it indicates that GM8126 will always be at the wakeup status and never enter to the sleep mode. If Pin 2 and Pin 3 are short, it indicates that GM8126 will be wakening up from the sleep mode by pressing the button, PB10. For the IPCAM application, Pin 1 and Pin 2 of J28 must be short. Table 2-3 lists and describes the definition of the SYS_WAKEUP connector (J28). Table 2-3. SYS_WAKEUP Connector (J28) Pin No. Signal Name Description 1 Pull 3V3 Source 2 SYS_WAKEUP Destination 3 Push bottom Source J29 is used to control the system power. If Pin 1 and Pin 2 are short, it indicates that the EVB power will always be turned on. If Pin 2 and Pin 3 are short, it indicates that the EVB power will be controlled by the PWREN signal of GM8126. For the IPCAM application, Pin 1 and Pin 2 of J29 must be short. Table 2-4 lists and describes the definition of the SYS_PWREN connector (J29). Table 2-4.
