Notes
|
|
=====
|
|
|
|
This BSP supports single LEON3-processor system with minimum peripheral
|
|
configuration of one UART. BSP reads system configuration area to get
|
|
information such as memory mapping and usage of interrupt resources and
|
|
installs device drivers based on this information.
|
|
|
|
There are no restrictions on memory mapping of UARTS. Console driver
|
|
operates in polled mode.
|
|
|
|
Console driver uses timer 0 of General Purpose Timer and must be configured
|
|
to use separate interrupts for each timer. No restrictions on memory mapping.
|
|
Interrupt request signal can not be shared with other devices.
|
|
|
|
Ethernet MAC core can be mapped in arbitrary memory address space and use
|
|
arbitrary interrupt request signal. Interrupt request signal can not be
|
|
shared with other devices.
