I'm trying to flash the OBP on my Netra T1 105 by netbooting the flash image. However, booting fails with the message
Quote:
10a000 Memory Address not Aligned


I'm using patch 108673-02, which Sun indicates is the most recent revision. The system already has Gentoo installed and normally boots without difficulty. I have already verified that the motherboard jumpers are in the correct positions to allow flash updating.

To extract the OBP image, I downloaded the signed patch from SunSolve and did:
Code:
% jar xvf 108673-02.jar
% cd 108673-02.jar
% grep "^->" "Update.to.nordica.3.10.27.FCS+nvinit-.di@OS" | cut -c3- > bundle_tmp
% uudecode bundle_tmp && rm bundle_tmp
% uncompress flash_bundle.tar.Z && tar xf flash_bundle.tar


I verified the checksum of the flash update file with:
Code:
% sum -s obp_image | cut -f1 -d" "
% grep obp_image checksums | cut -f1 -d" "


Everything checked out, so I copied obp_image to /tftpboot and made a link to it from C0A80009. Then, from the OBP console, I did:
Code:
ok boot net


So far so good. Then comes:
Code:
10a000 Memory Address not Aligned


I've read that this can be caused by problems with the memory, but only the base memory module is installed, and I have no problems booting a Linux kernel on this machine. Has anyone encountered this problem before, or have any suggestions?

Thanks!
