| mithro | shenki: Actually that should be my or1k-fixing branch | 02:29 |

| shenki | $ export JIMMO=1 PORT=/dev/ttyACM1 CPU=or1k PLATFORM=mimasv2 TARGET=base | 03:12 |
| shenki | does that look correct? | 03:12 |
| mithro | Mimas doesn't work yet | 03:13 |
| shenki | which board can I use? | 03:13 |
| mithro | Only the Opsis at the moment | 03:13 |
| shenki | :( | 03:14 |
| shenki | I don't have a power supply at home for that | 03:14 |
| mithro | Don't have a 12V supply? | 03:14 |
| shenki | I will have to find one | 03:14 |
| mithro | I recommend looking at your old routers / switches / etc | 03:15 |
| mithro | Yay! tftp booting Linux on the Opsis | 03:19 |
| shenki | mithro: nice | 03:23 |
| shenki | ok, i have my opsis powered up | 03:24 |

| shenki | mithro: hrm. usb is not enumerating | 03:26 |
| mithro | shenki: Try moving JFX2-RST to pins 1-2 | 03:26 |
| shenki | mithro: hrm. where is that? | 03:28 |
| shenki | ah i see | 03:28 |
| shenki | mithro: no luck | 03:29 |
| mithro | shenki: You are using the large USB port on the front? | 03:30 |
| shenki | no :) | 03:31 |
| * shenki gets printer cable | 03:31 | |
| mithro | shenki: The other one can't be used for programming | 03:31 |
| shenki | mithro: cool. which make target should I use to load it up? | 03:33 |
| mithro | make flash | 03:33 |
| shenki | mithro: that worked. make firmware-connect did not tho | 03:37 |
| shenki | mithro: do i need to reset it? | 03:37 |
| mithro | shenki: After flashing need to power cycle | 03:37 |
| shenki | mithro: is there a button? | 03:37 |
| mithro | Nope | 03:37 |
| mithro | I need to figure out why | 03:38 |
| shenki | mithro: hrm, power cycling didn't seem to work | 03:42 |
| mithro | shenki: Once you have power cycled, you do a "make firmare-connect" then hit the button | 03:43 |
| shenki | ah, cool | 03:43 |

| shenki | then nothing | 03:43 |
| mithro | shenki: Yeah - it's jumping into the middle of nowhere now | 03:44 |
| mithro | shenki: Do a "hdmi2usb-mode-switch --clear-softcpu-firmware" then power cycle again | 03:44 |
| shenki | mithro: cool | 03:46 |
| shenki | mithro: any tips for setting up network booting? | 03:46 |
| mithro | shenki: Make sure you disable network manager from controlling the device | 03:46 |
| mithro | shenki: As it will loose link every reset and network manager gets unhappy | 03:47 |
| mithro | Then you should be able to do | 03:47 |
| mithro | "make tftpd_start" | 03:47 |
| mithro | and "make tftp" | 03:47 |
| shenki | mithro: should it work if i directly attach the board to my laptop? | 03:57 |
| mithro | shenki: Yes | 03:57 |

| shenki | not sure. i have my laptop configured to run one via xinetd | 04:05 |
| shenki | it's not getting a connection | 04:06 |
| mithro | hrm? | 04:06 |
| mithro | What does ethtool show now? | 04:06 |
| shenki | it shows a link | 04:06 |
| mithro | atftpd gives you a bunch of debug info... | 04:06 |
| shenki | mithro: does it need to be running at 1000mbit? | 04:12 |
| shenki | ethtool says it's at 100 | 04:12 |
| mithro | shenki: It should be running at 1000mbit | 04:12 |
| mithro | I'm going to run find some lunch | 04:13 |
| mithro | be back in 30 minutes | 04:14 |
| shenki | mithro: ok. i forced 1000 and turned off negotiation, and i got two packets from the opsis | 04:14 |
| mithro | It should have negotiated at 1000 -- I'm a bit worried about your network.... | 04:14 |
| shenki | im using the cable you gave me the other day | 04:14 |

| shenki | which makes sense, as it looks like i'm getting bad data from the opsis | 04:35 |
| shenki | there's no 'tftp get' packet | 04:35 |
| shenki | mithro: can we get any info out of the opsis? is there a way to make it respond to ping packets? | 04:39 |
| mithro | shenki: I pushed a small fix for the atftpd | 04:43 |

| tpb | Title: GitHub - mithro/qemu-litex at timer-fix (at github.com) | 05:55 |
| shenki | ok | 05:56 |
| mithro | If we can disable the or1k timer, that would be good | 05:56 |
| shenki | i thought we were going to go down the or1k timer path for now? | 05:57 |
| mithro | shenki: Until we got something booting / going | 05:57 |
| mithro | shenki: You got it all going now? | 06:07 |
| shenki | got it going until the panic. no userspace | 06:09 |
| mithro | Yeah - it panics on real hardware - gets to userspace in qemu | 06:09 |
| mithro | shenki: Fixing the uart past post early printk would help us see what the panic is | 06:16 |
| shenki | yeah | 06:17 |
| shenki | mithro: which device tree file does it use currently? | 06:18 |
| mithro | Dunno... the one committed? :-P | 06:20 |
| shenki | there are two that you have been modifying | 06:20 |
| shenki | it looks like the build process uses or1klitex.dts | 06:20 |
| mithro | rm arch/openrisc/boot/dts/or1klitex.dtb.S arch/openrisc/boot/dts/or1klitex.dtb | 06:21 |
| mithro | I assume that means we using that? | 06:22 |
| mithro | Wouldn't surprise me if the IRQ is configured wrong | 06:22 |
| shenki | yeah. i tested by removing or1ksim | 06:22 |
| mithro | shenki: Think you can make progress now? | 06:26 |
| shenki | yeah | 06:27 |
| shenki | i will make sure irqs are working | 06:27 |
