Hello,
I intend to implement a firmware update feature for my project, which
is based on stm32f4discovery.
My idea is to load a separated ELF file on the dataflash, which is
loaded using the approach described in the following video:
https://www.youtube.com/watch?v=oL6KAgkTb8M
When running this
I noticed several instances of preprocessor logic like this example
from register_driver() in fs_registerdriver.c:
#ifdef CONFIG_FILE_MODE
node->i_mode= mode;
#endif
But there doesn't seem to be such a Kconfig option.
Did I miss something? Or is this a remnant from a bygone era?
Thank

Hehehe, you are not the first one to notice it, in fact I commented
that this kind of code exist but is not implemented:
https://issues.apache.org/jira/browse/NUTTX-8
Patch are welcome! ;-)

To be a POSIX, Unix-like system, NuttX should support privileges.

Hi Tanushree,
It seams the error is related to documentation, maybe if you disable
generating it the binutils will compile.

NxFLAT is currently only supported on ARM 32-bit and ARM Thumb ISAs.
Some development would be required to extend that to other architectures.
1. Can an ELF file be executed from dataflash too?
No. ELF cannot run XIP (eXecute In Place) in NOR FLASH. That is
because the ELF module is only partially linked and requires run-time
relocations to the ELF image to access the data area arbitrarily located
in RAM.
An option is to use
beside the privilege, it's more useful to modify the timestamp for IoT
device by utime:
https://pubs.opengroup.org/onlinepubs/009604599/functions/utime.html
BTW, the permission is meaningless in FLAT mode with the unsafe
language(e.g. C/C++).
