Welcome to the wiki!

Requirements:

Shall have:

• RP2040 with dedicated Flash (>= 2MB): 4 MB selected
• ICE40UP5K FPGA with dedicated flash (>= 2MB): 4MB selected
• Micro USB connector or USBC: Micro USB
• FPGA programming from the RP2040
• TBD additional lines from the RP2040 to the FPGA for misc data transfer: using 8 wires for this.
• RP2040 can program FPGA flash (Flash boot) as well as FPGA directly (SRAM mode)
• RP2040 exposes Flash as a flash drive for drag-drop programming of the FPGA
• Reset button to the RP2040
• Dedicated pushbutton for RP2040 and FPGA
• Dedicated LED for RP2040 (3 color?), 3 color LED for FPGA
• Clean 12MHz clock: RP2040 supplies a clock to the FPGA using GPIO_0

Should have:

• All FPGA pins brought out to headers: Done
• All RP2040 pins brought out to headers: Most pins are brought out.
• As many pins on PMOD ports as possible: We have 3 dual-PMOD (FPGA) and 1 dual PMOD (PICO)

May have
