Embedded Linux®: Hardware, Software, and Interfacing

The Target PBRs

Each target platform will need to fulfill all of the following requirements in order to be used for Project Trailblazer designs:

• PBR-1— The target board will use Linux kernel 2.4 or greater. Running the same kernel version across all target platforms would be nice, but it is not necessary. The engineers discovered that the i386, ARM and PowerPC kernel development occurs at different paces. ARM and PowerPC kernel patches don't always exist for the most recent version of the kernel.

• PBR-2— The target board will execute the bash shell. Exiting from the bash shell causes the bash shell to re-execute.

  TIP

  Defining boot requirements and evaluating target boards forms a development system baseline. Having a bash prompt on all your targets ...
