Project Info

It seems both routers are in working state (one maybe have some problems with software). For experiments with LEXRA LX5280 SoC which is romless processor with external memory in TSOP48 case.

LEXRA LX5280 was quite popular SoC for routers because I have RTL8181 and RTL8186 in 3 projects:
