Hi there,

You are now in the Rescue.

If you want to :
1/ Reset your counter, invoke "reset_boot_count"
sh: rescue.jeeves.bootfrom: unknown operand
2/ Repair your product (will erase both rootfs bank), invoke "update "
3/ Wipe your drive (will totally wipe the drive), invoke "wipe "
4/ Mount the user data, invoke "mount_user_data mount"

Then reboot your product.

===== Notes =====

==== Toolchain ====

  * The Ubuntu 12.04.2 LTS version of the arm-linux-gnueabi toolchain is broken for this target. A U-Boot image will successfully compile but will not boot. The LaCie GPL U-Boot source will not compile at all (processor Thumb support error).
  * The Ubuntu 13.04 version of the same toolchain works.

==== Functional Specs ====

=== CPU Address Decoding ===
Sheeva CPU core has 13 address windows:
  * 4x for CPU access to DRAM CS
  * 1x for CPU access to internal registers
  * 8x configurable for CPU access to remaining chip resources
== DRAM Windows ==
  * 8-bit BASE & SIZE registers
  * BASE corresponds to address bits [31:24]
  * Min. SIZE (0x01) = 16MB; max. SIZE (0xFF) = 4GB
  * SIZE is a mask; only 8 legal values (0x01, 0x03, 0x07, 0x0F, etc.)
== Register Window ==
  * Fixed SIZE of 1MB
  * BASE register
== Configurable Windows ==
  * 16-bit BASE & SIZE registers
  * BASE corresponds to address bits [31:16]
  * Min. SIZE (0x0001) = 64KB; max. SIZE (0xFFFF) = 4GB
  * SIZE is a mask; 16 legal values
=== SATA Address Decoding ===
  * 4x address windows
  * SDRAM and PCIe interface access
=== GbE Address Decoding ===
  * 6x address windows
  * SDRAM interface access only
=== USB Address Decoding ===
  * 4x address windows per USB port
  * SDRAM interface access only
=== SDIO Address Decoding ===

Wish I found this earlier (kirkwood/cpu.c): Linux expects the internal registers to be at 0xF1000000

Internal registers base address is set in register offset 0x20080 (arch-kirkwood/kirkwood.h): i.e. 0xF1020080 = 0xF1000000
