tftp on ppcboot 1.1.5

tftp on ppcboot 1.1.5

[gao xiaoguo]

I want to use tftp to download file into target machine,but always failed.
The tftp server on linux has already been setup and tested, I tftp a file successfully
by using other tftp client on windows.

Following is my environment and operation log, and I found the ip/udp datagram on network
really is 0.0.0.69->192.168.1.105,so nobody will answer to the tftp request. Why the
ip address of server is changed from 192.168.1.105 to 0.0.0.69 ? Are there something
I leave.

Following is different in my case (8260ADS board):
- Load address is 0x500000 (this may not be a problem)
- ethaddr is 00:11:22:33:44:55 (this prevented tftp in my case
   with similar symptoms as you describe if I used
   a1:b2:c3:d4:e5:c6, and I dont know why, and could
   be the problem in your case)
- tftp server has full path in inetd.conf; i.e. in.tftpd -s /tftpboot
  and then use tftp 0x500000 /tftpboot/testfile (this may not
  be a problem)
- Another possibility (as in my case of another similar board),
  the board was not setup properly in start.S.

First octet must be an even number, i.e. a0:b2:c3:d4:e5:c6 should be o.k.
The last bit in the first octet is the multicast bit.
The first bit in the first octet is the I/G address bit (Individual /Group) and
signifies if the OUI (first half of the MAC address) is universal (set to 0) or local (set to 1).
The second bit in the first octet must be set to 0.

I believe this has been addressed before on this list.

K.D.

Get yourself a valid MAC address.

Also, questions like this are off-topic here; you should ask  PPCBoot
related stuff on the ppcboot-users mailing list.

8260 and SPI driver

[Julien Eyries]

Hello !

I have searched the archive for an 8260 SPI driver and found some
messages related to this topic, but it seems to me there is currently no
working 8260 SPI driver. could someone confirm me that point ?


thanks,
