| MadHacker | xobs: re: mneasi's issues above - Catalina seems to work fine, got two tomus here I've just dfu-util'd to check and they're happy. | 08:29 |
|---|---|---|
| xobs | MadHacker: thanks for checking! | 08:29 |
| MadHacker | xobs: Guessing he might be having the problem with them locking up the bus depending on the hub thing if they're on the original firmware. | 08:29 |
| xobs | I think most of the Catalina issues we've run up against are based on quarrantining. | 08:30 |
| MadHacker | Oh wait. No. Fomu not tomu. | 08:30 |
| MadHacker | Sec. May have the wrong widget. <rummages in bag!> | 08:30 |
| MadHacker | No, both are fine. :D | 08:31 |
| MadHacker | (i.e. I've just dfu-util'd successfully both types of device on 10.15.2) | 08:32 |

| MadHacker | Hm, new Arduino just released. Seems expensive. | 09:38 |
| xobs | Yeah? | 09:38 |
| MadHacker | https://store.arduino.cc/portenta-h7 <-- I do not understand the target market for a 90eur board. | 09:39 |
| tpb | Title: Portenta H7 (at store.arduino.cc) | 09:39 |
| xobs | "AI" | 09:39 |
| MadHacker | On a 480MHz M7? Crappy AI. | 09:39 |
| MadHacker | I mean, you can get a Pi compute module 3+, which is MUCH more powerful, for about 20eur. | 09:40 |
| MadHacker | It feels poorly targetted. | 09:40 |
| MadHacker | The CPU on that board is about £13, qty 1. | 09:43 |
| xobs | Is Arduino looking for a new market, then? | 09:43 |
| MadHacker | Seems like they're trying to get into the SoM market for IoT gadgets. | 09:44 |
| MadHacker | But at that price, the SoM is going to dominate the cost of the gadget, and constrain the overall pricing horribly. | 09:44 |
| MadHacker | I mean, you've built commercial gear, can you imagine a Chumby with that as the brains? | 09:45 |
| MadHacker | Not viable. | 09:45 |
| MadHacker | (commercially) | 09:45 |
| MadHacker | I mean, a chumby guts kit, which I assume made some profit, was $139. And had a screen and various plastics etc. | 09:46 |
| MadHacker | (I'm just using chumby as a reference point here for an IoT widget that needed a moderately quick CPU) | 09:46 |

| mithro | xobs: I wonder if we should create our own custom fork of dfu-util which we can customize better with improve error messages and stuff? | 15:16 |
| MadHacker | Is upstream reluctant to accept changes? | 15:26 |
| MadHacker | That particular error about the DFU suffix is just confusing for everyone, for example. | 15:27 |
| tnt | which error ? | 15:29 |
| MadHacker | "dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!" | 15:30 |
| MadHacker | "dfu-util: Invalid DFU suffix signature" | 15:30 |
| MadHacker | It doesn't really care, never has, and the suffix doesn't seem to be helpful for anything. | 15:31 |
| tnt | Ah but isn't that because the file is named ".dfu" which in theory is a specific image format with metadata in it and here you just use it as a flat binary ? | 15:31 |
| MadHacker | It does the same with any flat binary. The error suggests that flat binary support is going away, which it isn't. | 15:33 |
| MadHacker | If it instead said "Please use --flat-binary for flat binaries" or something, it'd be more reasonable. As is, it's just unhelpful. | 15:33 |
| tnt | yeah true, re-reading the code logic it's a bit ui broken, but that change should definitely be upstreamed. | 15:35 |
