| xobs | Hey all, I'd like to announce the release of `wishbone-bridge` as a Rust crate. It's up at https://crates.io/crates/wishbone-bridge and current docs are at https://docs.rs/wishbone-bridge/1.0.0/wishbone_bridge/ | 13:30 |
|---|---|---|
| tpb | Title: wishbone_bridge - Rust (at docs.rs) | 13:30 |
| xobs | It's the first release of the core that powers `wishbone-tool`, with the goal of making it easy to write thin wrappers around programs that interact with a device under test. | 13:31 |
| xobs | It's still all located within `https://github.com/litex-hub/wishbone-utils/`, and it's the same backend bridge library that's still being used by `wishbone-tool`. | 13:32 |

| TMM | This is probably a silly question but is there a programming limit on FPGAs like on flash? | 15:54 |
| daveshah | Flash FPGAs, yes | 15:55 |
| daveshah | SRAM FPGAs, no | 15:55 |
| TMM | Oh, some FPGAs have flash on the board itself? | 15:55 |
| TMM | or on the chip itself I guess | 15:56 |
| daveshah | Some FPGAs have flash on die | 15:56 |
| daveshah | MachXO and some microsemi ones | 15:56 |
| TMM | Ah, and others load it dynamically on 'boot'? | 15:56 |
| daveshah | Even MachXO does as the FPGA array is still SRAM based | 15:56 |
| daveshah | It just has microcontroller style built in flash that it loads from by default | 15:57 |
| daveshah | Some FPGAs, Microsemi in particular, do have genuine flash based arrays still aiui | 15:57 |
| TMM | Alright, so if I wanted to design a board with one 'empty' fpga that can be programmed from the OS on it I'd want one that ram based and load the code from the main cpu? | 15:57 |
| daveshah | Yes | 15:58 |

| atommann | Hi _florent_, The reset button of KC705 is active high. My board's reset signal is active low. How can I change this logic? | 16:25 |

| _florent_ | atommann: you can invert it as done on Arty for example: https://github.com/enjoy-digital/litex/blob/master/litex/boards/targets/arty.py#L41 | 17:06 |

| atommann | Hey, the RESET logic works fine now! | 17:34 |
| atommann | Thank you _florent_. | 17:34 |
| atommann | Memtest still fail. Tomorrow I read more issues to see the workaround. | 17:35 |
