| wolfspraul | llhdl and antares still 404... | 00:00 |
|---|---|---|
| wolfspraul | maybe I dig in my archives somewhere and upload a mirror | 00:01 |
| wolfspraul | ok I temporarily uploaded llhdl and antares until Sebastien gets to it, then I delete again... https://github.com/weidu/llhdl https://github.com/weidu/antares | 01:48 |
| Fallenou | wolfspraul: ok thanks for the upload :) | 07:40 |
| wolfspraul | very welcome | 07:41 |

| Fallenou | nice | 11:58 |
| wpwrak | hmm. so the layout guys converted one of the ground layers of m1rc3 to a signal layer. | 12:07 |
| wpwrak | so we should look for parallel green-green lines, as they could have crosstalk. the light green power trace behind J16 has a dark green trace underneath it for a while. | 12:08 |
| wpwrak | and there's also green-green fun below the label "C225" | 12:09 |
| Fallenou | they removed a ground layer ? | 12:10 |
| wpwrak | and of course north and northeast of J27 | 12:10 |
| Fallenou | I guess they know what they're doing since they do layout for graphics card, mother boards etc | 12:10 |
| Fallenou | at least they know better than me :p | 12:10 |
| wpwrak | looks promising, though. the routing of the dvi signals looks nice. i just hope trace length isn't nearly as critical as some of those data sheets want to make us believe | 12:11 |
| wpwrak | trust is good. control is better ;-) | 12:12 |
| Fallenou | I guess we won't be able to output 4k resolution anyway :p | 12:13 |
| Fallenou | 4k is the new "HD" marketing term, it will soon pop on every package =) bigger bigger bigger ! | 12:14 |
| wpwrak | 4k was yesterday. now it's 8K UHDTV | 12:14 |
| Fallenou | 8k OLED | 12:14 |
| Fallenou | \o/ | 12:14 |
| wpwrak | if the folks at ITU have done a good job, then even 8K UHDTV will have some CGA-like fallback mode. like even USB 3.0 still includes good old low-speed. marketine people like this. "<B>USB <BLINK>3.0</BLINK> compliant ports</B> <FONT size="0.5pt">Low-speed</FONT>" | 12:17 |
| Fallenou | lol ! | 12:18 |
| Fallenou | AFAIK USB 3.0 is so "different" than 2.0 they had to include a complete 2.0 host inside the 3.0 host | 12:19 |
| Fallenou | in order to keep compatibility | 12:19 |
| wpwrak | remember, they did just the same with high-speed | 12:19 |
| Fallenou | hum really ? | 12:20 |
| wpwrak | took years before the EHCIs started to disappear | 12:20 |
| wpwrak | UHCI for full and low plus an EHCI for high | 12:20 |
| Fallenou | oh ok | 12:20 |
| Fallenou | then you have OHCI for both full low and high ? | 12:20 |
| wpwrak | they're in the same chip. with a switch for the signal lines. doesn't get much cruder ;-) | 12:20 |
| wpwrak | yes, low an high were always together | 12:21 |
| wpwrak | i.e., there's no USB 0.x that only does low-speed ;-) | 12:21 |
| Fallenou | hop polled uart is working :) | 19:32 |
| Action: Fallenou has a bios prompt working with irq disabled | 19:32 | |
| lekernel | :) | 19:46 |
| Fallenou | ok exception handler is executed when I read from a non mapped address on real FPGA | 20:20 |
| Fallenou | right now exception handler disables MMU and prints "TOTO" and then return | 20:20 |
| Fallenou | it returns to the code which was previously running :) | 20:20 |
| Fallenou | so far, so good | 20:20 |
| Fallenou | now let's analyze existing mapping an re-map the faulty page | 20:21 |
| Fallenou | and* | 20:21 |
| Fallenou | not sure if I can retrieve the virtual address which caused the fault from the exception handler right now | 20:21 |
| Fallenou | let's commit a bit in order to show that progress has been made :p | 20:24 |
