[ptxdist] Mini2440 not mounting

Hi Everyone

I have, what it seems, a problem with my mini2440 in that its not mounting
to my host, I think I might be missing some settings and if anyone can
correct me I'd really appreciate it. I'm using a Mini2440 1gig nand.

I have the following:

1. Using BSP and ptxdist versions 2012.12.0.

2. my host network setup is : a) Address  - 192.168.1.7
                                           b) Netmask - 255.255.255.0
                                           c) Gateway - 192.168.1.2

3. my target network setup is : a) Address  - 192.168.1.27
                                             b) Netmask -  255.255.255.0
                                             c) Gateway -  192.168.1.2
                                             d) ethaddr -
00:04:f3:00:06:35
                                             e) Serverip -    192.168.1.7

4. I have NFS on my host, not sure if i should use NFS or TFTP and not sure
what the difference is, if any.

5. The log from my mini2440 serial output:

6. I did not run ptxdist platformconfig, because I don not fully understand
what the image has to be. Do I have to run this and select an image, if so,
what image should i use?

7. I do not know where the mini would mount to, maybe that is the main
issue. In the docs its written that the tftp server is /tftpboot, but I
dont have a directory like that anywhere.

8. I made some changes to the
"configs/platform-friendlyarm-mini2440/barebox-128m-env/config" like
changing the autoboot timeout, but when I run go 0x31000000, it boots and
uses default 3 second timeout.

9. I am not sure what the nfsroot setting should be, and when I change it,
it defaults to what it was:

        if [ -n $user]; then
                                 nfsroot =
"${eth0.serverip}:/home/${user}/nfsroot/${machine}"

        else
                  nfsroot = "/path/to/nfs/root"

10. I do not receive any errors as my bootup log shows, yet i can not copy
the barebox image from the board support package to the directory ised by
the tftp server "cp platform-mini2440/images/barebox-image
/tftpboot/barebox-mini2440" because the directory
/tftpboot/barebox-mini2440 does not exist.

thank you for any help

Regards

Ruben Louw

Hi Dave

Thanks for the reply, I managed to get the kernel booting and my board
mounted, I realized that tftp was not configured correctly.

All seems to work 100% now.

Thanks

Regards

Ruben,

It might be more appropriate to post to this group:

http://blog.gmane.org/gmane.comp.embedded.ptxdist.oselas.community

for mini2440 related stuff.


I'll try to answer:

6) you have to run this command and for your device:
   ptxdist platform configs/platform-friendlyarm-mini2440/
   platformconfig-NAND-128M
7) you generally make a directory in root on your host called /tftpboot and I
   think it generally has user permissions.   
8) modifying boot behaviour is covered in the Quickstart guide.  It took a
   a fair while for me to get my head around, the result of which is the
   diagram on the bottom of page 47
9) for my NFS setup the line after the else statement is:
   
   nfsroot="home/davef/Pengutronix12/platform-mini2440/root"

   Change to wherever you have installed the latest mini2440 BSP
