keesjis there an example of include some verilog code, perffably I would like a wishbone slave where I can instanciate my module13:40
keesjI did find litex_read_verilog (to read convert to python) but from memory there was also some "include" possibilites13:41
acathlakeesj, find an example with something like : "platform.add_source()"13:50
_florent_keesj: you have a look at: https://github.com/enjoy-digital/litex/wiki/Reuse-A-Verilog-VHDL-nMigen-Core14:11
_florent_and also to some cores integrated in Betrusted, I2C for example: https://github.com/betrusted-io/gateware/blob/master/gateware/i2c/core.py14:12

keesjok nice.. and.. if I want to replace my Soc with magic python code I set cpu_type to None?14:29
keesjI remember also somebody being able to use the uart and debug on fomu14:30
_florent_setting cpu_type=None removes the CPU from the SoC (ie you just get the SoC infrastructure)14:31
keesjbecase the litescope adds with_etherbone but I guess there must then be a similar options for taking over the serial as wishbone master14:32
_florent_yes with add_uartbone14:33
keesjyes, it looks like serial is still already obtained by SoCCSRHandler https://pastebin.com/1PeBgNnn even when I set the cpu type to None15:00
tpbTitle: INFO:SoC: __ _ __ _ __ INFO:SoC: / / (_) /____ | |/_/ - Pastebin.com (at pastebin.com)15:00
acathlakeesj, you must set : kwargs["uart_name"] = "crossover"15:12
acathlaso your uart won't be connected to anything but accessible through wishbone reads/writes15:13
keesjthat does produce a different result :P15:13
acathlaand the real uart used as a wishbonebridge15:13
keesjhttps://pastebin.com/pV5yJZjL a lot of grep and code reading involved here :P15:15
tpbTitle: INFO:SoCBusHandler:csr added as Bus Slave.INFO:SoCCSRHandler:bridge added as C - Pastebin.com (at pastebin.com)15:15
keesjgetting hot !15:17
keesjyup.. awesome...15:21
keesjnow I need to combine this with a verilog module, nice15:37
