20 | ===== |
---|
21 | |
---|
22 | This BSP supports single LEON3-processor system with minimum peripheral |
---|
23 | configuration of one UART. BSP reads system configuration area to get |
---|
24 | information such as memory mapping and usage of interrupt resources and |
---|
25 | installs device drivers based on this information. |
---|
26 | |
---|
27 | There are no restrictions on memory mapping of UARTS. Console driver |
---|
28 | operates in polled mode. |
---|
29 | |
---|
30 | Console driver uses timer 0 of General Purpose Timer and must be configured |
---|
31 | to use separate interrupts for each timer. No restrictions on memory mapping. |
---|
32 | Interrupt request signal can not be shared with other devices. |
---|
33 | |
---|
34 | Ethernet MAC core can be mapped in arbitrary memory address space and use |
---|
35 | arbitrary interrupt request signal. Interrupt request signal can not be |
---|
36 | shared with other devices. |
