Look-aside configuration of Intel FPGA

A configurator loads FPGA/CPLD bit streams into devices which is usually managed by a microcontroller. The Oasis configurator has served well until recently we run into shortage of NXP KL02 Cortex-M0+ microcontroller, which has always been used as a FPGA configurator.

For the short term, we have studied feasibility of

• Replace KL02 with KL03. This device has less RAM (2KB vs. 4KB) than KL02, but requires minimal change against KL03
• Replace KL02 with 8051. This old device had been used on many legacy products, but it is subjected to phase out

In the long term, replacing KL02 with STM32G061 and redesign of general configurator based on Zephyr is planned.
