A.1

Restore the Platform Kernel

Just in case if the kernel or flash is corrupted, follow the below steps to recover the
kernel and root file system.

1.

Connect the EKI-1121L/1122L/1124L with console.

2.

Press Ctrl + C when power on the EKI-1121L/1122L/1124L.

3.

You should see the following messages.

4.

Start your TFTP server and put the kernel.lzo and jffs2fs.img under the TFTP 
directory.

5.

Assume your TFTP server's IP is 172.21.73.101. Use the following commands.

6.

After EKI-1121L/1122L/1124L startups, You may encounter following or similar 
CRC errors:

jffs2_get_inode_nodes: Node header CRC failed at 0x06add4.

{df0e,e002,df4edf4e,df4edf4e}

This is because that part of flash space is not formatted according to the jffs2
format.Generally speaking, this is not a problem. In this case ,you just need
restart the EKI-1121L/1122L/1124L.

7.

After restart, it should be work. But if you encounter other warnings,please look 
over Chapter 5 "Troubleshooting".
