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>

/* This linker script supports running NuttX in the 'Non-Secure' (ns) domain
|
|
* in conjunction with TrustedFirmware-M (tfm).
|
|
*
|
|
* NuttX will run as the 'Non secure application' in the 'Non-Secure image
|
|
* primary primary slot Area 1' in internal flash. Compare [UM2851],
|
|
* Figure 7. Furthermore, see Figure 18 for the SRAM1 area used for 'Non-
|
|
* Secure application volatile data'
|
|
*
|
|
* While the 'Non-Secure Image primary slot Area 1' is actually 640KiB large
|
|
* in the referenced setup, the image will be enriched with a header of 0x400
|
|
* bytes and a trailer of 0x2000 bytes. Thus the 'flash' statement in the
|
|
* MEMORY definition below.
