Icesugar-pro FPGA Development Board Lattice ECP5 Open Source RisC-V Linux SODIMM
More information https github com wuxx icesugar proIntroduction iCESugar pro is a FPGA board base on Lattice LFE5U 25F 6BG256C which is fully supported by the open source toolchain yosysnextpnr the board is designed in DDR2 SODIMM form with 106 usable IOs with on board 32MB SDRAM it can run RISC V Linux the on board debugger iCELink base on ARM Mbed DAPLink support drag and drop program you can just drag the FPGA bitstream into the virtual disk to program and with a additional USB CDC serial port direct connect to FPGA so you can only use one TYPE C cable to develop and test Features Master chip Lattice ECP5 LFE5U 25F BG256 24K LUT MEM Block RAM Multiplier PLL The onboard debugger iCELink supports drag and drop burning virtual serial port JTAG connects to 32MB SDRAM and supports RISC v Linux Mount 32MB SPI Flash W25Q256 Use DDR SODIMM ports to route 106 I OS Fully developed using open source toolchainMain control chip Lattice LFE5U 25F 6BG256C 24 k LUTs 18Kb x 56 sysMEM Blocks 1008 KB Embedded Memory 194 KB Distributed RAM bits 28 18 x 18 Multipliers PLLxlThe debugger The onboard iCELink debugger Support drag and drop to burn Bitstream filescommand line burn Supports virtual serial ports Support JTAG compatible with CMSIS DAP debuggingPeripherals Type c USB is used for power supply download and debugging 32 MB SPI Flash W25Q256 32 MB SDRAM IS42s16160B RGB leds are used for testing Onboard 25Mhz clock crystal oscillator SDCARD
