To allow offline installation, the "liteiclink" package has to be installed before the "liteeth" package. Otherwise, to satisfy the dependency requirements, the setup will attempt to download the "liteiclink" package from the internet and will consequently fail. 2023-08-16 09:39:03 +02:00

Icenowy Zheng c1d8db396d build/gowin/common: Fix DDRInput
The DDRInput of Gowin seems to be never used and contains a typo that
prevents it from being really used.

Fix this typo.

Florent Kermarrec 577674bff2 test: Add minimal test_spi_mmap with simulation of SPIMaster. 2023-08-04 17:51:22 +02:00
Florent Kermarrec 688dae0112 cores/spi: Add new SPIMMAP core allowing doing SPI accesses directly from MMAP.
Implements a new SPIMMAP module, allowing accessing multiple SPI peripherals directly
from MMAP. It allows configurable SPI transactions: mode, bit order, and data width.

Developed and funded through a collaboration with MoTeC.

Example of integration:

# SPI MMAP ---------------------------------------------------------------------------------
spi_pads = Record([("clk", 1), ("cs_n", 8), ("mosi", 1), ("miso", 1)])
spi_mmap_tx_region = SoCRegion(origin=0x8000_0000, size=4096, cached=False)
spi_mmap_rx_region = SoCRegion(origin=0x8000_1000, size=4096, cached=False)
self.spi_mmap = SPIMMAP(
    pads          = spi_pads,
    data_width    = 32,
    sys_clk_freq  = sys_clk_freq,
    tx_origin     = spi_mmap_tx_region.origin,
    rx_origin     = spi_mmap_rx_region.origin,
    tx_fifo_depth = 32,
    rx_fifo_depth = 32,
)

self.bus.add_slave(name="spi_tx",
    slave  = self.spi_mmap.tx_mmap.bus,
    region = spi_mmap_tx_region,
)
self.bus.add_slave(name="spi_rx",
    slave  = self.spi_mmap.rx_mmap.bus,
    region = spi_mmap_rx_region,
)
self.irq.add("spi_mmap", use_loc_if_exists=True)

Root cause still need to be understand, but when testing with another AsyncFIFO (from verilog axis),
the behavior was similar. So is it an Efinity issue? Constraint issue?

Florent Kermarrec 72a1592bee litex/gen: Add initial/minimal LiteXContext to easily get build context from modules.
Still a PoC and need to think a bit more about it, but will allow fixing AsyncFIFO issue
on Efinix FPGAs.
