Q: linux failed to execute /init?

Q: linux failed to execute /init?

[Jack Harvard]

Hi,

I'm trying to boot Linux, but the /init process failed. Here is the
info:

=FF<6>/init exit code: -14
/init exit code: -14
<4>Failed to execute /init
Failed to execute /init
 <6>/sbin/init exit code: -14

Just wondering what do those different exit codes mean?

Thanks, -J

#define EFAULT          14      /* Bad address */

Also, before the init process hung up and printed out /init exit code:
-14, it printed out the following symbol
ÿ
Which doesn't make any sense to me, just wondering what could have
caused this? it's unlikely due to baud rate and printed out something
unreadable.

ÿ is 255. While this could indicate a serial transmission error (my
guess: bad timing), printing -14 repeatedly certainly does not.
Is the ÿ reproducable, does it happen every time?

This is reproduceable and it happens every time. IMHO, I also suspect
this could be caused by some obscure timing issues, as the kernel is
booting up from an FPGA-prototyped SoC, the same Linux image was
running fine on a previous build of FPGA-prototyped SoC,  but it's
coming across this /init failed problem repeatedly on the currently
running newly built bit file.

Here is the terminal printout from the correct bootup on a previous build.

<6>Freeing init memory: 584K
Freeing init memory: 584K
init started:  BusyBox v0.60.5 (2006.06.15-11:12+0000) multi-call binary
Bummer, could not run '/etc/init.d/rcS': No such file or directory
ÿ
Please press Enter to activate this console.

It looks that it's printing out several ÿ first and then replaced them
with "init started: BusyBox..." seems quite obscure, as the only
difference between those two FPGA builds is they were built at
different runs using exactly the same source files.

Sounds like a problem in your drivers, and/or your memory controller. 
Especially the memory controller.

-14 is EFAULT. This means that there was some access
to memory that was not mapped.

In the future, check /usr/include/asm/errno.h for exit
codes. Of course in user-space they are positive with
-1 being return from the function-call and errno being
set to this code. In the kernel, they are combined with
'error' being the negative of the return code.
