Peter McGoron 06cf8807c3 Progress on PicoRV32 ... 1) The PicoRV32 bus was not generated correctly. Running "finalize" on the bus, which is what the SoC does, does not generate the bus logic correctly. I don't know if this is a bug or if the SoC bus generator is only meant to be used in the main SoC. Currently the bus logic is copied from the LiteX finalize code. 2) Add test micropython code to load code. 3) Removed BRAM. The Wishbone cache was messing with the direct implementation of the BRAM because the BRAM did not implement all the bus features correctly. LiteX has a Wishbone "SRAM" module, and despite it's name it can also generate BRAM if there are available BRAM. This is how the ROM and the startup RAM are implemented. The PicoRV32 ram is now using this SRAM.		2024-02-20 15:36:53 +00:00
