This BSP is for the LEON2 SPARC V8 processor developed by the European Space Agency and Gaisler Research. The LEON2 includes serial ports and timers on the CPU so one BSP can support many of the LEON2 boards. LEON2 is available as a synthesizable VHDL model, allowing custom implementations on FPGA and/or ASIC. There are also standard components available, in particular the rad-hard Atmel AT697 for space applications.

The BSP supports two network interfaces: the Opencores Ethernet MAC and the LAN91C111 i/f. The Opencores MAC is a soft macro and used pre-dominantely on FPGA boards, while the LAN91C111 is used on boards with the AT697.

The startup procedure for LEON BSPs is explained in SparcBSPStartup.

Board Setup

If there are special jumper or ROM monitor settings, describe them.

Downloading and Executing
