USB_D 6 AC23 IFC_ADDR 24 USB_D 7 For more information see P7010 QorIQ Integrated Processor Hardware Specifications 2 Implementing Mux Strategy In QorIQ SDK 1 0 1 the mux strategy for PIOLORDB is static by nature The interfaces are decided at the time of power on reset POR depending upon the reset configuration which means primarily the POR signals that the device samples at the time of reset The same interfaces remain available in u boot and Linux The above strategy has been implemented primarily for the boot interfaces bus interfaces such as SD IFC and USB ULPI For other interfaces that are multiplexed on P101O0RDB such as TDM CAN and SPI CSO can be configured through nwconfig through CPLD register writes This table describes the QorIQ SDK 1 0 1 muxing Table 2 SDK 1 0 1 Muxing Switch Selection Interfaces Available in u boot and Linux Boot location through Bus selection SD USB ULPI IFC NOR IFC NAND IFC CPLD SPI Flash TDM amp CAN sw4 through SPI SLIC swe NAND Flash IFC CSO on No No Yes Yes Yes Conf Conf Conf NAND Flash NOR Flash IFC CSO on No No Yes Yes Yes Conf Conf Conf NOR Flash Enabling SD Interface on P1010 Reference Design Board Rev 0 2 Freescale Semiconductor Enabling SD Interface Table 2 SDK 1 0 1 Muxing continued Switch Selection Interfaces Available i2. 92103 559 German 33 1 69 35 48 48 French www freescale com support Japan Freescale Semiconductor Japan Ltd Headquarters ARCO Tower 15F 1 8 1 Shimo Meguro Meguro ku Tokyo 153 0064 Japan 0120 191014 or 81 3 5437 9125 support japan freescale com Asia Pacific Freescale Semiconductor China Ltd Exchange Building 23F No 118 Jianguo Road Chaoyang District Beijing 100022 China 86 10 5879 8000 support asia freescale com For Literature Requests Only Freescale Semiconductor Literature Distribution Center 1 800 441 2447 or 1 303 675 2140 Fax 1 303 675 2150 LDCForFreescaleSemiconductor hibbertgroup com Document Number AN4336 Rev 0 07 2011 Information in this document is provided solely to enable system and software implementers to use Freescale Semiconductor products There are no express or implied copyright licenses granted hereunder to design or fabricate any integrated circuits or integrated circuits based on the information in this document Freescale Semiconductor reserves the right to make changes without further notice to any products herein Freescale Semiconductor makes no warranty representation or guarantee regarding the suitability of its products for any particular purpose nor does Freescale Semiconductor assume any liability arising out of the application or use of any product or circuit and specifically disclaims any and all liability including without limitation consequential o
