Booting the system via NFS[edit | edit source]

It is assumed that the development environment has been set up properly as described here.

Assuming that:

  • the CPU module is booting with a working FSBL (or U-boot SPL for BELK-4.0.0/BXELK-2.0.0) and U-Boot image (either from flash NOR SPI or flash NAND or MicroSD card)
  • a kernel image is available and ready to be downloaded through tftp
  • the root file system has been uncompressed into a nfs share

the system can boot using the net_nfs[a] configuration, as described here.

  1. The net_nfs configuration, besides setting the system for booting from the network, triggers a command (program_fpga) which loads the FPGA binary from TFTP and programs the bitstream.
