Rev. 1.0 --5 September 2012 4 of 41 Mini3250 User Manual Chapter 1 Mini3250 Introduction Mini3250 is designed as a compact, stable, and reliable ARM-based module board. It is ready to be the core of your new product. The Mini3250 measuring only 75mm by 55mm, however it has integrated one LCD connector, one MicroSD card socket and one USB 2.0 OTG port on board, which helps to speed up your development sharply. 1.1 Processor Introduction The Mini3250 is based on NXP's 32-bit ARM926EJ core microcontroller LPC3000 series, which is the only ARM9 microcontroller that provides a vector floating-point co-processor. The LPC3000 series is able to run in ultra-low-power mode even down to 0.9V, as well as the lowest power consumption. The LPC3000 series owns abundant peripheral resource, one of the most distinguishing features is to provide 7 UART controllers which is rare in ARM microprocessors, moreover, it integrated a USB 2.0 OTG controller, Ethernet controller and so on. With such outstanding performance, the Mini3250 is perfect to be employed in Industrial field, Medical Equipment, Intelligent Instrument, Consumer Electronics, Communication Product, and etc. 1.2 Features Microprocessor: NXP LPC3250, operates at 208MHz up to 266MHz A 32 KB instruction cache and a 32 KB data cache on chip Up to 256 KB of internal SRAM Memory SDRAM: 64MB NANDFLASH: 128MB NORFLASH: 4MB, up to 32MB supported Connector Extended via double 2.0mm pitch 3 lines 27-pin respectively connectors One JTAG port on the rear of the board (Optional) One 40-pin LCD connector MicroSD Card Socket One USB OTG 2.0 connector, mini-B type, with ESD protection Indicator One power indicator One programmable LED Other facility Watchdog timer, supported with the microprocessor RTC Mini3250 User Guide Timll Technic Inc .

The Stage 1 Loader (S1L) is a robust third level boot loader written by NXP Semiconductor to simplify and enhance the LPC3250 booting procedure. The S1L is feature rich with the ability to configure clocking, virtual memory mapping, data and instruction caches, the ability to access NAND flash, and the ability to boot applications/images from the NAND flash, SD Card, or serial port to name a few of the features the S1L provides. Mini3250 adapt Uboot as the Bootloader for Linux. Uboot is a general free open source boot program that supports many kinds of processors; it is similar to BIOS on PC but much more powerful. Uboot supports features like booting from Ethernet and loading various kernels to NANDFLASH. Uboot is free open source code software based on GPL. 3.2 Linux Kernel If user need add or delete some character is respectively to or from kernel, or increase certained hardware support to kernel. To modify the drive compiled into kernel, user need recompile the kernel. The following steps will describe how to generate the kener image for the MINI3250 with the Linux develop kit in the supplied CD. 3.2.1 Generate Kernel Image The supplied CD provide the Linux develp kit for the Mini3250, user can use it to coustomilize the system and generate the kernel image. 1> Uncompress Linux kernel package The name of kernel source pack is "linux-2.6.27.8_mini3250.tar.bz2".
