White Rabbit and soft-CPU. The "White Rabbit Core" contains a soft-CPU based on lm32. Here, some information is given on the development environment of this soft-CPU. The lm32 on PEXARIA2A is a bit different, since PEXARIA2A does not have a UART. Therefore, the console output is redirected to the JTAG interface. Please keep in mind, that this is a temporary solution.
