mithro: please help me with style (especially CAPS where not appropriate) and the issue mentioned on irc. any suggestions on how to get migen to emit binary? Am seeing "ERROR: expected configuration string starting with '0b' for parameter 'RGB0_CURRENT' on cell 'SB_RGBA_DRV'" because my binary was evaluate to a decimal constant (.RGB0_CURRENT(2'd3). Thanks. |
|
Note that this is not register compatible with foboot impl, I opted for a separate mux register to make the bits align. I'm planning an emulation of this block for other platforms and want it to be for n leds so the mismatching bits don't work too well. |
|
I think you need an str in there somewhere. Poke me tomorrow when I'm not in a bar. :-) |
|
@TomKeddie It seems like the str fixed the issue? |
|
mithro: yes, thanks. I feel like I need to test this code more but am looking for a nod that this is what you intended and is moving in the right direction. Thanks. |
|
mithro: when you have a moment please give this a once over, thanks. |

Actually put it where ever the sram region is suppose to go.

Can you rebase this on master? |
