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:
|
|
|
|
```shell
|
|
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.
