真佩服他们的创造力，BGA用双面板就搞定了！如果把软件做好，这个路由器价格可是天下无敌！ [upload=jpg]UploadFile/20036917201428420.jpg[/upload]

型号图上可以看到的，CX82100。在电脑市场很多摊上都是。 正好你可以测试一下你的JTAG，看看是否支持。要不要转给你？

台湾公司也一样，不把DATASHEET公开。我已经问他们要了一份。需要的话。我传上来。

原来该芯片没有串口，失败啊。只好通过外扩串口芯片了。 • Single-chip, high-performance processor with integrated network interfaces − ARM940T processor − Advanced Microcontroller Bus Architecture (AMBA) with two internal busses ♦ Advanced System Bus (ASB) ♦ Advanced Peripheral Bus (APB) − 16k x 32 internal ROM − 8k x 32 internal RAM − External Memory Controller (EMC) − Two identical 10/100 Mbps IEEE 802.3 Ethernet Media Access Controllers (EMACs) with MII/7-WS interfaces − USB 1.1 Slave Interface − General Purpose Input/Output (GPIO) signals − Timers − Interrupt Controller (INTC) − Clock Generators • ARM940T processor − ARM9TDMI Core − Advanced System Bus (ASB) interface − Advanced Peripheral Bus (APB) interface − Separate 4 kB instruction and 4 kB data caches − Write-back cache scheme and write buffer optimize performance and minimize ASB traffic − Five-stage pipeline with fetch, decode, execute, memory and write stages − ‘TrackingICE’ mode allows a conventional ICE (in-circuit emulator) mode of operation • Dual Media Independent Interface (MII) interface to 10/100 Ethernet PHY • Host Parallel Expansion Bus interface to Flash ROM and other devices • Parallel interface to SDRAM/SRAM • JTAG interface • 22 general purpose I/O lines (13 available for application use, 6 available for application use if optional signals for EEPROM, Host Parallel Expansion Bus, and Clock are not used, and 3 dedicated to system signals) • 196-pin FPBGA

台湾Marvell的88E6052。台湾的好东西就是多，又便宜。 The 88E6052 is a 5+2 integrated switch,with five PHY ports and two MII ports.

ARM网站上有很多path下载，可能你需要打打补丁。
