* tsim

Download tsim from ftp://ftp.gaisler.com/gaisler.com/tsim/

Note that the free version of tsim supports 32MB of DRAM; you will need
to reduce the number of embedded binaries to get the kernel to fit in
tsim's memory.  Copy conf/embedbin/default.mk to conf/embedbin/local.mk
and adjust appropriately.

   % tsim-leon3 -mmu -nosram obj/kern/kernel.init
     ...
   tsim> go

* Run on real hardware

Download grmon-eval from ftp://ftp.gaisler.com/gaisler.com/grmon/
Disable firewall rules that might block grmon's UDP packets.

   % grmon-eval -nb -eth -ip 171.66.3.253
   grlib> load obj/kern/kernel.init
   grlib> run

To run grmon over a JTAG parallel port cable, as root:

   # grmon-eval -nb -grlib -jtag
