| Hasan | fixed file path bug, now it uses current working directory, looks for the pluto file in current working directory and generates pdf based on that. Fixed and tested Artur Scholz | 05:07:48 |

 Artur Scholz | Some updates on development guidelines: https://librecube.gitlab.io/development/overview/ | 12:06:11 |
| Artur Scholz | Babalola Emmanuel: Finally I was able to open your battery board expansion (https://gitlab.com/librecube/prototypes/platform-battery-expansion-board) with the latest KiCAD version. Good job - board will be produced in the next days. | 15:00:54 |
| Artur Scholz | cajt: Will you share your raspi design? | 15:14:26 |
| Artur Scholz | Turns out the Raspi 5 has 4 UARTS available at GPIO, so it can be routed directly to CubeSat connector. | 15:14:56 |
| Artur Scholz | bingnan: Babalola Emmanuel , and anyone else interested in KiCAD: I added the second CAN controller in the raspi-proto board schematic. What's left to do is the parts placement and routing: https://gitlab.com/librecube/templates_and_tools/prototype-boards/-/tree/main/src/electrical/prototype-board-raspi?ref_type=heads | 16:57:42 |

cajt: Will you share your raspi design? But its 4-layer and still misses some minor stuff, like interrupts lines and the second-chip select. Also some symbols and footprints might need some attention. Like the HC-49 crystal can ist probably too long. Didn't touch any of that due to the 4-slayer thing. | 19:19:47 |

| cajt | There is an Issue with collected RIDs.
Some major aspects of the design are left unchecked.
Also is there a refence Implementation for this, or is everything new? Especially the interfacing chain from mcp2518 upto the linux driver should be verified before commiting to board design and manufacturing. | 06:35:52 |

| cajt | ... that RISC-V FPGA thingy | 12:56:27 |
| cajt | btw, there is also seL4, RTEMS and Linux support for that thingy (at least the polarfire soc) | 14:59:41 |
| cajt | there is acutally a radiation hard version, different size fabric, but they don't give SEE test data without an NDA, but claim to reach at least 100kRad. But I have no use for that anyways. | 15:08:47 |
 Red | I just saw a server from the Open Compute project., with FPGAAAAA | 15:11:29 |
| cajt | Yeah, data processing and networking is a good fit for FPGAs | 16:08:51 |
| cajt | But IOs and timing critical stuff fits well | 16:10:34 |

hi everyone 🤠Hi 👋 | 17:55:42 |
| dpmj | I'm Juan, a telecom engineer from Spain. I'm developing a CubeSat board and came across librecube. Your work is really impressive, thanks a bunch. | 17:57:15 |
| dpmj | I have a technical question tho | 17:58:05 |
| dpmj | I started gathering documentation before I started development, about a year ago, and downloaded the librecube bus specification from you (a spreadsheet in gdocs). I've just realised that you've changed it | 18:00:56 |

| dpmj | In some areas, there's been a regression in redundancy and compatibility with some COTS and other open source projects (specially the CAN B placement). I'm not criticising, I'm just wondering why this change was made. | 18:09:06 |
