| mithro | cr1901_modern: So - Formally Verified SPI core, huh? :-P | 00:16 |
|---|---|---|
| cr1901_modern | mithro: Yes, under certain conditions | 00:21 |
| cr1901_modern | mithro: I started adding asserts/assumes to Migen as well, so I can go back to coding using Migen. Too much Verilog is bad for the digestive tract. | 00:21 |
| mithro | cr1901_modern: Yeah :-P | 00:23 |
| cr1901_modern | In any case, what I've formally verified is "if no transfer is taking place, the contents of a hypothetical shift register attached to my SPI core >> | 00:28 |
| cr1901_modern | will match the value of `din` to my SPI core _just_ before the transfer took place for all time/all reachable states." | 00:28 |
| mithro | cr1901_modern: I have no idea what that actually means :-P | 00:29 |
| cr1901_modern | I've formally verified my SPI core actually transfers data to its destination correctly, and ditto for receive | 00:29 |
| cr1901_modern | mithro: Adding asserts to HDMI2USB might be interesting | 00:31 |
| cr1901_modern | I wouldn't know what to prove though :/ | 00:31 |

| mithro | cr1901_modern: So -- where are we at with xmodem stuff? | 01:19 |
| cr1901_modern | mithro: Current status is debugging qemu xfers; they don't work :D. That's all I know right now. Timer fix appears to be working just fine. And the xfer terminates w/ 11 NAKs (normal failure) | 01:20 |
| cr1901_modern | Everything else works and this is the only thing blocking me from making a pull | 01:21 |

| mithro | _florent_: Confirmed that the Arty Ethernet now works here! | 06:41 |
| _florent_ | mithro: ok cool, what are you doing with Arty? Preparing miniconf? | 07:08 |
| mithro | Yeah | 07:08 |
| mithro | Just about to test Linux | 07:09 |
| _florent_ | ok, is linux alreadt working on one board? | 07:09 |
| _florent_ | already | 07:09 |
| mithro | We get early parts of the kernel booting fine, doesn't quite get to user space.... | 07:10 |
| mithro | Gets to userspace in QEmu | 07:12 |
| _florent_ | ok that's what i was going to ask | 07:12 |
| _florent_ | do you have an idea of what is going on? | 07:14 |
| mithro | _florent_: I believe shenki thinks it is something with the IRQ stuff | 07:14 |
| mithro | As the crash happens as soon as we switch trying to using the uart via IRQ rather than polling | 07:15 |
| _florent_ | mithro: ok, where is the linux code? (just want to look at the uart code) | 07:20 |
| mithro | _florent_: https://github.com/mithro/linux-litex/tree/litex-minimal | 07:21 |
| tpb | Title: GitHub - mithro/linux-litex at litex-minimal (at github.com) | 07:21 |
| mithro | _florent_: You need to be using the or1k-linux branch of litex | 07:33 |
| mithro | Interesting, it looks like we are saying that the IRQ value for the uart is 2, but the "interrupt_map" seems to indicate it should be 0? | 07:59 |
| mithro | constant,uart_interrupt,0,, | 08:00 |
| mithro | constant,timer0_interrupt,1,, | 08:00 |
| mithro | constant,ethmac_interrupt,2,, | 08:00 |

| mithro | shorne: morning! Any chance we could get you set up with our environment this weekend? | 21:36 |
| mithro | shorne: it would be a huge stress relief to have someone who knows what they are doing with the Linux kernel having the thing going. | 21:39 |
| mithro | shorne: as shenki decided to run off to Taiwan for 2 weeks | 21:39 |
