README

^^^^^^

README for NuttX port to the SAM4CMP-DB board.
|
||||
|
||||
http://www.atmel.com/tools/SAM4CMP-DB.aspx
|
||||
|
||||
The board is intended to test NuttX SMP features for dual Cortex-M4.
|
||||
|
||||
|
||||
Settings
|
||||
^^^^^^^^
|
||||
1. Both CPUs are running at 92.160MHz with PLLB.
|
||||
2. Serial console can be used via on-board USB-UART (115200/8/N/1)
|
||||
3. Interrupt handlers such as timer and UART are handled on CPU0
|
||||
4. Both CPUs share internal SRAM0 (128KB)
|
||||
5. SRAM1 is used to boot CPU1.
|
||||
6. Cache controllers are disabled because of no snooping features.
|
||||
|
||||
Status
|
||||
^^^^^^
|
||||
Currently SMP freature works on the board but is not stable.
|
||||
|
||||
1. "nsh> sleep 1 &" works without crash.
|
||||
2. "nsh> smp " sometimes works but some assertions might happen.
|
||||
3. "nsh> ostest " causes deadlocks during the test.
