LimeSDR Mini V2 Build Instructions

To build gateware for the limesdr_mini_v2 target, run:

python3 -m boards.targets.limesdr_mini_v2 --build

Note

Ensure that the required toolchain is installed and configured before building. See Requirements for the board-specific requirements.
Run the build command from the project root directory.

Available Build Options

Command:

python3 -m boards.targets.limesdr_mini_v2 --build [--load] [--flash] [--flash-user] [--flash-golden] [--toolchain=TOOLCHAIN] [--cable <cable>]

Options:

--load: Load the bitstream into SRAM.
--flash: Program the combined user and golden image into SPI flash.
--flash-user: Program the user bitstream at address 0x00000000.
--flash-golden: Program the golden bitstream at address 0x00140000.
--toolchain=TOOLCHAIN: Select trellis or diamond. The default is trellis.
--cable <cable>: Specify the JTAG cable. The default is ft2232. Use openFPGALoader --list-cables to list supported cable names.

After generating the user bitstream, the following files are available:

limesdr_mini_v2.bin: Combined image containing both the golden and user bitstreams.
tools/limesdr_mini_v2.mcs: The same image in Intel Hex (iHex) format.

Note

Due to limitations in prjtrellis, Lattice Diamond must be installed and available in $PATH to generate tools/limesdr_mini_v2.mcs.

For supported programming cables and required hardware connections, refer to the following hardware documentation section:

Note

Only the section covering the FT2232H Mini Module and the required hardware connections is relevant for board programming with this project.

To write bitstreams to SPI flash:

Full flash image (user + golden):

python3 -m boards.targets.limesdr_mini_v2 --flash

User bitstream only:

python3 -m boards.targets.limesdr_mini_v2 --flash-user

Golden bitstream only:

python3 -m boards.targets.limesdr_mini_v2 --flash-golden
