Armzone QT2410

The armzone.com qt2410 is a 90% compatible chinese remake of Samsungs SMDK2410. Unfortunately it's only 90% compatible, not 100% - and those 10% difference are only marginally documented.

[edit] 概述

QT2410包含主板(Mainboard)和核心板(Kernel board). 核心板通过一个144脚的SDRAM插座插入主板.

[edit] Boot Selection

QT2410有一个位于主板的512k字节的NOR flash(SST39VF400A)和一个位于核心板的64MB NAND flash (Samsung K9F1208U0B).核心板有一个小开关来决定是从NAND flash启动还是从NOR flash 启动.

[edit] USB Downloader in NOR

NOR flash预置了"S3C2410X USB Downloader ver 0.2"的小程序，这个程序监听usb设备端口等待下载程序。下载完程序后，跳到刚刚下载的代码处运行。

原装的QT2410附带一些bogus的windows程序来向板子下程序. User:HaraldWelte已经写了叫做s3c2410_boot_usb的程序在Linux主机上同USB downloader交互。

[edit] JTAG flashing

NAND和NOR flash可以通过JTAG烧写。这是万不得已的方法，因为它极其耗时间。Samsung / Armzone附带了windows下的烧写工具，叫做sjf2410， User:HaraldWelte移植了一个linux版的，叫做sjf2410-linux。使用它，你可以重新烧写Bootloader到NAND，万一什么奇怪的事情发生的话

[edit] NAND

The 64MB NAND Flash is partitioned as follows: 

0x00000000: u-boot, 196kByte (can shrink later, lots of debug code)
0x00030000: u-boot environment, 16kByte (cannot shrink, 16k erase size of NAND)
0x00034000: kernel, 2MB (0x200000 bytes)

Armzone QT2410

The armzone.com qt2410 is a 90% compatible chinese remake of Samsungs SMDK2410. Unfortunately it's only 90% compatible, not 100% - and those 10% difference are only marginally documented.

概述

QT2410包含主板(Mainboard)和核心板(Kernel board). 核心板通过一个144脚的SDRAM插座插入主板.

Boot Selection

QT2410有一个位于主板的512k字节的NOR flash(SST39VF400A)和一个位于核心板的64MB NAND flash (Samsung K9F1208U0B).核心板有一个小开关来决定是从NAND flash启动还是从NOR flash 启动.

USB Downloader in NOR

NOR flash预置了"S3C2410X USB Downloader ver 0.2"的小程序，这个程序监听usb设备端口等待下载程序。下载完程序后，跳到刚刚下载的代码处运行。

原装的QT2410附带一些bogus的windows程序来向板子下程序. User:HaraldWelte已经写了叫做s3c2410_boot_usb的程序在Linux主机上同USB downloader交互。

JTAG flashing

The NAND and NOR flash can be flashed via JTAG. This is discouraged by all means, since it is extremely time-consuming. Samsung / Armzone ship (again) a windows based program for flashing, called sjf2410. User:HaraldWelte has done a Linux port of sjf2410, called sjf2410-linux. Using it you can re-program the Bootloader into NAND in case something strange happened.
