Hi James,

Just letting you know I have an initial port of j1b to the ESP5 fpga. I intend to target the tinyFPGA-EX board once it get's released ..

I have used the opensource Yosys/nextpnr/trellis workflow ..

Initial timing suggests the j1b should run at 70Mhz and use ~6000 LUT's I will update once I have hardware ..
