Lattice Mico32

The Lattice Mico32 port uses the system_config.h generated by the Mico System Builder to retrieve the properties of the peripherals.

Implemented (in shared/ subdirectory) Polled console driver (uart) Clock interrupt with 10 ms tick Networking using Lattice tri-speed ethernet MAC

TODO

Support more peripherals:

• uart driver using interrupts

To on the simulator included in lm32-gdb use these commands:

tar sim --hw-device lm32cpu \
  --hw-device "lm32uart/reg 0x80006000 0x100" \
  --hw-device "/lm32uart > int int0 /lm32cpu" \
  --hw-device "lm32timer/reg 0x80002000 0x80" \
  --hw-device "/lm32timer > int int1 /lm32cpu" \
  --memory-region 0x08000000,0x4000000
load

The simulator is VERY VERY slow when RTEMS is idle. To speed this up, add SIMULATOR_FAST_IDLE=1 to the configure command.
