fm10k-dump

Utility that allows dumping the SPI Flash Non-Volatile Memory of the FM10000 family of cards.

Requirements

• GCC >= 4.4.0 or clang
• make
• fm10k kernel module compiled with UIO.
  • # cd src && make clean && make -j $(nproc) CONFIG_UIO=1 && make install CONFIG_UIO=1
  • # rmmod fm10k && modprobe uio && modprobe fm10k
  • If this works an UIO device (/dev/uio0) will exist. If not, check your bifurcation settings and/or whether the slot supports 16x PCIe 3.0

Compilation

• $ make clean && make
• You can specify whether to use gcc or clang this way: $ make CC=gcc / $ make CC=clang
• An executable named ./fm10k-dump should now exist.

Usage example

• If the chip on the card is known to the tool, it'll set the image size to match. Alternatively it will use the platform minimum of 8Mbit.
• # ./fm10k-dump /dev/uio0 outputImage.bin
• You can also force the image/chip size: # ./fm10k-dump /dev/uio0 outputImage.bin 32
