    NAND flash and SDRAM. The lifetime of memory chips is limited and availability can also be limited from time to time. Embedded Artists make every effort to mount the original design chip on the board. In case that is impossible a compatible chip will instead be mounted without any prior notice. There can be small programming differences between mounted brands.

  • Page 26: Nand Boot Problem Fix

    Board is formed by AND:ing N_STCS0 and N_STCS1. This, in turn, enables the databus buffer (U11 on LPC3152 OEM Board) when the DBUF_EN jumper (pin 1-2 on J40) is inserted on the LPC31xx Base Board. See Figure 8 to locate DBUF_EN jumper on the LPC31xx Base Board.
  • Page 27 For the XNOR gate the output is high when both inputs are low. This will also solve the problem, since the databus buffer (U11 on LPC3152 OEM Board) will not be enabled during NAND boot when both N_STCS0 and N_STCS1 are low.

  • Page 28: Getting Started

    The LPC31xx Base Board contains a USB-to-Serial bridge chip (FT232R from FTDI) that connects the UART channel on the LPC3152 to a virtual COM port on the PC (via USB). It is this serial channel that is the console interface to the system.

    The LPC3152 User’s Manual from NXP contains all details about booting including the pre-defined MMU table. The rest of this section gives an overview of what is supported by the LPC3152 OEM Board and LPC31xx Base Board, and how to quickly get started with the download process.

  • Page 33: Creating A Boot Image

    LPC3152 Developers Kit - User’s Guide Page 33 USB – DFU class The boot image is downloaded via the USB by utilizing the DFU class (Device Firmware Upgrade). A Windows application exists that connect to the DFU device (that the LPC3152 implement in boot mode).
  • Page 34 LPC3152 Developers Kit - User’s Guide Page 34 Figure 14 – lpc3131xImgCreator Command Line Options To add a CRC header to the binary file, i.e., to create a CRC attached boot image, the command is: lpc313xImgCreator -o ./ -pc -i lpc313x.bin The -o option specifies the output directory (the current directory in this case).

  • Page 35: Booting Via Uart

    When booting via UART, a terminal program (on a PC) that can send binary images must be connected to the LPC3152 UART channel. The USB-to-serial bridge can be used to connect to the LPC3152 UART channel. Alternatively the RS232 interface can be used directly. Make sure the jumpers on the LPC31xx Base Board are correctly set for the interface option selected.
