B4860QDS is a high-performance computing evaluation, development and test platform supporting the B4860 QorIQ Power Architecture processor. B4860QDS Overview ------------------ - DDRC1: Ten separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s, ECC, 4 GB of memory in two ranks of 2 GB. - DDRC2: Five separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s, ECC, 2 GB of memory. Single rank. - SerDes 1 multiplexing: Two Vitesse (transmit and receive path) cross-point 16x16 switch VSC3316 - SerDes 2 multiplexing: Two Vitesse (transmit and receive path) cross-point 8x8 switch VSC3308 - USB 2.0 ULPI PHY USB3315 by SMSC supports USB port in host mode. - B4860 UART port is available over USB-to-UART translator USB2SER or over RS232 flat cable. - A Vitesse dual SGMII phy VSC8662 links the B4860 SGMII lines to 2xRJ-45 copper connectors for Stand-alone mode and to the 1000Base-X over AMC MicroTCA connector ports 0 and 2 for AMC mode. - The B4860 configuration may be loaded from nine bits coded reset configuration reset source. The RCW source is set by appropriate DIP-switches: - 16-bit NOR Flash / PROMJet - QIXIS 8-bit NOR Flash Emulator - 8-bit NAND Flash - 24-bit SPI Flash - Long address I2C EEPROM - Available debug interfaces are: - On-board eCWTAP controller with ETH and USB I/F - JTAG/COP 16-pin header for any external TAP controller - External JTAG source over AMC to support B2B configuration - 70-pin Aurora debug connector - QIXIS (FPGA) logic: - 2 KB internal memory space including - IDT840NT4 clock synthesizer provides B4860 essential clocks : SYSCLK, DDRCLK1, 2 and RTCCLK. - Two 8T49N222A SerDes ref clock devices support two SerDes port clocks - total four refclk, including CPRI clock scheme Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Shaveta Leekha <shaveta@freescale.com> Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Sandeep Singh <Sandeep@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
