I had the same problem installing Debian 8 'Jessie' on a SheevaPlug. I solved it temporarily by doing the following:
- In u-boot: setenv machid 00000692 saveenv - Then install normally. The 'make the system bootable' phase will fail because flash-kernel fails: ---- /var/log/installer/syslog: May 16 13:47:28 in-target: Setting up u-boot-tools (2014.10+dfsg1-5) ...^M 4-kirkwood May 16 13:47:46 in-target: Unsupported platform. May 16 13:47:46 flash-kernel-installer: error: flash-kernel failed May 16 13:47:46 main-menu[170]: WARNING **: Configuring 'flash-kernel-installer' failed with error code 1 May 16 13:47:46 main-menu[170]: WARNING **: Menu item 'flash-kernel-installer' failed. ---- - Then select 'execute a shell' and write: cd /target/boot/ /target/usr/bin/mkimage -A arm -O linux -T kernel -C none -n uImage -a 0x00008000 -e 0x00008000 -d vmlinuz uImage /target/usr/bin/mkimage -A arm -O linux -T ramdisk -C none -n uInitrd -d initrd.img uInitrd - It may be neccesary to change 0x00008000 to 0x00800000 in both cases, but in my case it worked the way above. - Then 'exit' the shell and select 'continue without boot loader'. - I think that this last phase of mkimage should be repeated on every kernel upgrade because I think flash-kernel (which calls mkimage) will fail again.
