replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)). The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used. Signed-off-by: cuiziwei <cuiziwei@xiaomi.com> |

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.
