Technical Specifications Lattice ECP5-25F FPGA In csfBGA285 Package (-8 Speed Grade) - 24K LookUp Tables - 1008 Kb Embedded Block RAM - 194 Kb Distributed RAM - 28 18x18 Multipliers - PLLs: 2 - Internal Oscillator - Flexible I/O For DDR3 Memory Support DDR3L Memory - 128 Mbytes (1Gbit) - 64M x16 - 1.35V Low Voltage Operation Micro USB Connection - Full-Speed (12Mbit) USB With Direct Connection To The FPGA Non-Volatile Storage - 128Mbit QSPI FLASH Memory - Bootloader (First 4Mbits) - User Bitstream - User Storage (Firmware/MSC Backend) - QSPI Compatible - MicroSD Socket - 4Bit SD Interface (CK, CMD, DAT0-3) Power Supply - High Efficiency DCDC For Main Supplies - Battery Charger (100mA) With Charge Indicator LED - LiPo Battery Connector (PH Type) 48MHz Onboard Oscillator Standard 0.05" JTAG Connector User I/O - 1x Button - 1x RGB LED - 20x I/O On 0.1" Headers Analog System - Analog Mux - SAR ADC, External RC/Input Comparator Of FPGA - Digital Bypass - Internal Channels For Supply Monitor - Battery Voltage Sensing Feather Format Board - Dimensions: 22.86mm x 50.8mm Review: OrangeCrab r0.2.1 with 512MiB memory - The board I got is actually the r0.2.1 with 512MiB of memory, way better! Looking at the chip I see D9SHD, which if I look up on the Micron website is a MT41K256M16 (256*16bit). It has a USB-C connection instead of Micro-USB. The orangecrab-examples verilog examples and linux-on-litex-vexriscv examples work, once I change 25F to 85F (e.g. --device 85F, or the appropriate change to --85k instead of --25k in the Makefiles). Have to use 'dfu-util --alt-0 -D' to program new bitstreams.
