Hi Stella,
the failure seems more Mini2440 platform related than PTXdist related. So, our
OSELAS community mailing list would be a better location to discuss this
issue.

Ohh, yes. I just start my kernels via TFTP and NFS. Longer time not tested if
they still fit into the NAND partition.... :(

The "2048k(kernel)" part defines a 2097152 space in the NAND for the kernel,
but the kernel file itself is of 2155440 bytes in size. *BANG*
Yes. The current 3.14 Linux kernel is too large for this small NAND partition.
You now have the choice (as Alexander already pointed out):
- enlarge the kernel partition by modifying Barebox's default configuration
in "configs/platform-friendlyarm-mini2440/barebox-128m-env/config" or at
runtime with the (same) file in "/env/config"
- or shrink the kernel. By accident I have left the symbol inclusion enabled
in the current kernel config.
Without these symbols the kernel is smaller and should fit again into the
existing NAND partition.

To disable the symbols, run:
$ ptxdist menuconfig kernel
General setup --->
-*- Configure standard kernel features (expert users) --->
[ ] Load all symbols for debugging/ksymoops <------------ disable it
These symbols are required for debugging purposes only.
This also reminds me: the 3.14 kernel config is a copy of the 3.13 config,
which is a copy of the 3.12 config, which is a copy of the 3.11 config...
All these kernel images will not fit into the NAND kernel partition due to
enabled debug symbols. m( ...I'm going to change it.
Regards,
Juergen
