[Vendor: Embedded Solutions AG]

The UNC20 Developer’s Kit for Linux includes a UNC20 module, a baseboard with schematics, and LxNET ES, a Linux distribution based on uCLinux for ARM7 processors.

Features of LxNET ES include . . .

uCLinux v2.4.290 kernel for the ARM7TDMI
uClibc v0.9.16
BusyBox v0.60.3
Dynamic loading of modules
Supported filesystems: CRAMFS, JFFS2, NFS
Support for on-chip 10/100 Ethernet
Debugging via gdbserver over serial or Ethernet
Embedded web server (thttpd)
Flash programming utilities
EEPROM support

As part of LxNET ES, a complete GNU toolchain is provided, including C and C++ compilers (GCC v2.95.3) and debugger (GDB v5.2.1) and DDD graphical user interface. LxNET ES requires a Linux workstation. All sources are included, including code developed by Embedded Solutions, and can be used royalty-free.

The UNC20 Developer’s Kit includes the Parallel port JTAG (PPJ) which is built directly onto the development baseboard. Using PPJ, developers can debug and reprogram flash memory by using a PC parallel port. A parallel port cable is included in the Developer’s Kit. No additional BDM or JTAG tools are needed to work with the UNC20 Developer’s Kit

The UNC20 microcontroller module combines a 32-bit RISC processor, 16 Mbyte SDRAM, up to 8 Mbyte Flash and Ethernet MAC and PHY in a compact 48 pin DIP package – ready to be designed into your system.

The microcontroller on the UNC20 is the NetSilicon’s NS7520, a 32-bit microprocessor specifically designed for use in intelligent networked devices and Internet appliances. The NS7520 includes a 32-bit RISC ARM7TDMI core, 10/100BaseT Ethernet MAC and two independent serial ports.

Features of the UNC20 module in the Developer’s Kit include . . .
