| mithro | xobs: Greg is here looking at foboot on his OrangeCrab | 13:34 |
| mifune | got my python cpu emulator running in circuitpython with the help of xobs | 13:42 |
| buZz | mifune: what cpu are you emulating? :) | 13:45 |

| mifune | buZz: self designed 8bit isa. Primarily to learn and experiment with how a cpu works and the tools needed to implement one. | 14:10 |
| buZz | nice :) | 14:11 |
| xobs | Also handy for exercising python issues :) | 14:13 |

| pinoaffe | Hi everyone, I'm trying to build nextpnr but am running into an issue where it says make[2]: *** No rule to make target '/usr/local/share/icebox/chipdb-384.txt', needed by '/tmp/guix-build-nextpnr-ice40-0.0.0-0.c192ba2.drv-0/source/ice40/chipdbs/chipdb-384.bba'. Stop. | 15:32 |
| daveshah | You probably need to pass -DICEBOX_ROOT= to the nextpnr cmake with the path you have installed icestorm too | 15:33 |
| daveshah | it defaults to /usr/local/share/icebox | 15:33 |
| pinoaffe | daveshah: ah, that sounds reasonable, i'll give that a try | 15:34 |
| *** m0it has quit IRC | 15:35 | |
| Yatekii | xobs: do we have hardware pickup at the workshop or before? | 15:37 |
| xobs | Yatekii: either. You can come by and pick it up now if you like. Just show that you've got the toolchain installed. | 15:38 |
| Yatekii | xobs: I do have it installed ofc :) | 15:39 |
| Yatekii | xobs: where are you folks at? | 15:39 |
| Yatekii | I wanted to get into oss fpga ever since a talk like 5yrs ago | 15:39 |
| xobs | Hardware Hacking area, just to the right of the stage. | 15:39 |
| Yatekii | but I somehow always managed to miss/drop it and since there is a workshop now, that's the eprfect oportunity =)) | 15:39 |
| Yatekii | xobs: ok I'll try =D | 15:40 |

| CarlFK | the red USB block - seems at odds with "Fomu implements its USB in a softcore." | 17:54 |
| CarlFK | is the red block just the 4 usb connector fingers and maybe buffery components ? | 17:54 |
| tnt | The red block is the connector ... | 17:55 |
| tnt | and maybe 2 * 33R resistors. | 17:55 |
| tnt | Also, btw, it's not PSRAM (Pseudo Static RAM) it's SPRAM (Single Port RAM) | 17:56 |
| *** henrik has quit IRC | 18:00 | |
| daveshah | and, iirc, 15k not 16k of BRAM | 18:02 |
| daveshah | (120kbit) | 18:03 |
| tnt | yup | 18:03 |

| mifune | xobs: ive encountered a weird bug where my entire laptop locks up when using circuit python. The difficulty is that im not able to reproduce it, though it is during heavy load and in one ocasion had my mouse and keyboard were doing weird stuff. | 20:31 |
| mifune | is there a way to disable some of the usb periphals that appear when loading circuitpython? | 20:31 |
| xobs | mifune: not that I'm aware of. | 20:32 |
| CarlFK | mifune: were you doing any usb things, other than serial connection to python? | 20:59 |
| CarlFK | like HID or mouse or storage.... | 20:59 |
| mifune | it was probably doing something with storage, most issues are when it is parsing the python script | 21:04 |
| mifune | what i'm guessing is that it is related to the issues i had earlier this day, where the 0.1.1 version was suffering from not having enough time to handle the usb while accesing the flash. | 21:05 |
| *** alon has quit IRC | 21:27 | |
| xobs | Probably. We really do need to improve flash speed... | 21:34 |

| alon | note for fomu workshop people: reboot via wishbone-tool causes an endless loop - to workaround it you can use the following trivial script: | 22:28 |
| alon | ❯ cat $(which fomu-reboot)#!/usr/bin/python3# writing to the reboot CSR results in an endless loop. until fixing wishbone-tool this# is a workaround to reboot without clicking Ctrl-Cfrom subprocess import Popen, PIPEp = Popen(['wishbone-tool', '0xe0006000', '0xac'], stderr=PIPE)for i in range(3): l = p.stderr.readline()p.kill() | 22:28 |
