BleepshopAnybody herre toturing a Linsn RV901T ?03:19
BleepshopI'm wondering if the gateware has gotten to the point of being able to reflash the board via one of the PHYs.03:20

_florent_Bleepshop: Hi, I also have a Linsn RV901T, it should still work with LiteX but I haven't used it that much recently since switched to Colorlight boards for similar applications10:21
_florent_With Etherbone, you can control the internal bus of the SoC from your Host, so can reflash the board with a simple SPI peripheral10:23
_florent_ex on the ColorLight: https://github.com/enjoy-digital/colorlite/blob/master/colorlite.py#L77-L8310:24
_florent_with a simple script on the Host: https://github.com/enjoy-digital/colorlite/blob/master/scripts/test_flash.py10:24
_florent_Melkhior: Thanks for the framebuffer definition in the .dts. You are probably the first one trying to add a keyboard with Linux, we should probably first finish the GPIO IRQ support to enable that.10:30

cr1901_modern_florent_: What is the purpose of the "dev" option in litex_setup.py and why would one want to use it? If you're doing devel, wouldn't you _want_ to update litex_setup.py to merge/rebase?11:45
*** Melkhior has joined #litex12:01
Melkhior@_florent_ Yes, if there's no IRQ support for GPIO in Linux/Litex then ps2-gpio won't work12:02
MelkhiorI probably need the Ethernet more, but haven't investigated hwy it works as MII in the BIOS but doesn't work in Linux, maybe I'll try next week-end12:03
MelkhiorBut last week-end wanted to have a go at a 'Litex PC' with a screen and keyboard :-)12:04

_florent_cr1901_modern: litex_setup  by default does an auto-update, I use the dev option to disable it to be able to test the litex_setup when editing it14:36

Bleepshop_florent_: Thanks for the info. Now I need to get my shit together, get LiteX to install, hack together a JTAG adapter out of a Pi or Arduino and try this sometime as soon as I get the the CNC reassembled and off the workbench. LOL15:49

dormitoDoes litex (especially in the context of wishbone) have a method for handling crossing clock domains, or does that have to be done by han?19:42

*** cr1901_modern has left #litex19:43
zypdormito, as far as I know there's no wishbone cdc blocks yet, but there's an axi-lite cdc and adapters between wishbone and axi-lite19:50
