 2022-02-17 17:32:00 +01:00
Florent Kermarrec 1052584cf7 integration/soc/add_sdram: Use new AXIUpConverter when up-converting is required (Instead of going through Wishbone). 2022-02-17 17:23:16 +01:00

Florent Kermarrec c494ea231b cpu: Add initial NaxRiscv support (From out of tree prototyping in litex_naxriscv_test). 
- Supporting rv32ima for now.
- No interrupt support yet.
- AXI4 direct interfaces to LiteDRAM (fixed at 128-bit for now).
- AXI4-Lite interfaces to LiteX main bus.
- Pre-generated netlist used for now (need to allow customization/re-generation).
- Running in simulation with: litex_sim --cpu-type=naxriscv
- Running on hardware with: python3 -m litex_boards.targets.digilent_arty --cpu-type=naxriscv --build --load

Demo with Linux and Doom on SDS1104X-E scope:

Florent Kermarrec 38a047bed1 cpu: Add initial NEORV32 support (From out of tree prototyping in litex_neorv32_test repo). 
- Only configured for rv32i for now (need to create variants).
- I/DBus interfaces probably not optimal (latency).
- Converted from VHDL to Verilog through GHDL-Yosys-Synth (should also support direct VHDL use with toolchains supporting it).
- Interrupt not yet implemented.
- Running in simulation with litex_sim --cpu-type=neorv32.
- Running on Arty with: python3 -m litex_boards.targets.digilent_arty --cpu-type=neorv32 --build --load:

The BIOS can now initialize I2C peripherals during the boot.

self.submodules.i2c = I2CMaster(pads)
self.add_i2c_init_table("i2c", i2c_addr=0x4c, table=it6263_i2c_hdmi_tx)

it6263_i2c_hdmi_tx = [
  (0x05, 0x40),
  (0x04, 0x3D),
  (0x04, 0x1D)
