Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00 on A2GX260


 I'm attempting to use U-Boot 2013.01.01 to boot a Linux-3.10.31 kernel on a Arria II GX development kit board that is running a Nios II soft-core processor (with a MMU) with a 1 MB JFFS2 partition as the root file system. The on-board flash appears to probe correctly by identifying to two unique erase regions and the view reduction from 65536KiB to 16384KiB is expected. Everything seems to be fine during the booting process until the very end when the system is unable to access the shared libraries followed by a "Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00" error. The system appears to actually mound the JFFS2 file system before the panic occurs so it's not clear to me it's unable to access the proper directory for the shared library.  Some other relevant address information:  I have included a copy of the boot screen as a reference.CPU : Nios-II SYSID : 00000000, Mon Jul 06 13:50:05 2015 BOARD : 2agx260 *** Warning - bad CRC, using default environment  Net: No ethernet found. Hit any key to stop autoboot: 0 # # Booting kernel from Legacy Image at ce000000 ...  Image Name: Linux-3.10.31-ltsi-05131-g55fdf0  Image Type: NIOS II Linux Kernel Image (gzip compressed)  Data Size: 974773 Bytes = 951.9 KiB  Load Address: c8000000  Entry Point: c8000000  Verifying Checksum ...

Where did you install '' in your root file system?

Hi Kazu, 


I have since resolved the problem since my original post. It turns out that I didn't allocate enough space in the JFFS2 partition to for all of the file system. Once I increased the size of the partition, everything worked as expected.  


I assume one possible reason that couldn't be found was that particular file/directory didn't make into the file system when the smaller partition was in place. 


However, I appreciate your reply.
