evaput is a remote firmware uploader for the 5188, a client for EVA bootloader's FTP interface.

The 5188 is the only model which contains 2 AR7 SoCs. Both have their own RAM but only one has Flash for the firmware.
The second SoC gets the Bootloader uploaded via VLYNQ with the CPU variable set to 2 so the firmware knows where it runs.
After this the second SoC behaves like a normal box and can be "recovered" by evaput to receive the cloned firmware.

You can update eva urlader if you use mtd2+, be carefull.


rc.S of the 5188 first checks if /dev/mtd9 exists, if it does it is copied to /var/kernel.
If the size of /var/kernel is not zero its content is "flashed":

echo "Load RAM Kernel"
evaput26 -S $nfs_client_ip /var/kernel

If the size of /var/kernel is zero the content of mtdblock2 is "flashed":

echo "Load FLASH Kernel (ram kernel not valid)"
evaput26 -S $nfs_client_ip /dev/mtdblock2

If /dev/mtd9 does not exist the content of mtdblock2 is "flashed" too:

echo "Load FLASH Kernel (no ram kernel)"
evaput26 -S $nfs_client_ip /dev/mtdblock2
