## Known Issues
## Known Issues
- Many IPMI commands are unimplemented in this initial release, causing the OCCs to fail to come online [^2] [^3]. These commands will be implemented over the coming weeks and months.
- NextPNR continues to indicate timing failure even though the design operates as intended. This needs to be investigated and resolved.

- Microwatt is consuming around half of the entire FPGA on the Versa ECP5 -45 devices. This is due to issues within GHDL/Yosys/NextPNR, apparently triggered by the Microwatt codebase, that need to be investigated and resolved.
- Microwatt/LiteX is consuming around half of the entire FPGA on the Versa ECP5 -45 devices. This is due to issues within GHDL/Yosys/NextPNR, apparently triggered by the Microwatt/LiteX codebase, that need to be investigated and resolved.

Kestrel is an active development project at Raptor Engineering, and as such features will continue to be implemented over time. Our current focus is the remaining IPMI commands, followed by Microwatt size reduction in an effort to (re)enable Ethernet support. Linux is also on our roadmap, although timing is currently unknown due to the aforementioned blocking factors.

Kestrel is intended to be used on an upcoming Raptor Computing Systems product incorporating a much larger ECP5 FPGA. This product is not a standard PC form factor device, nor will it be a cost focused product, but it is designed partly as a development platform for Kestrel technologies. Look for more information on this specialty product later in 2021!
