| xobs | CarlFK: thanks, I'll update it. | 02:09 |
|---|---|---|
| xobs | CarlFK: Updated. You can see all of my ECOs there, too: https://tomu.im/fomu-evt1/ | 02:36 |
| CarlFK | xobs: neat. | 02:40 |
| CarlFK | lm32 and risc-v cores - are both little-endian? (passing on Q's from adafruit) | 03:04 |
| xobs | They're different endiannesses. I think it's lm32 that's big. | 03:07 |
| CarlFK | oh oh.. that means Circuit Python on lm32 may not fly... | 03:10 |
| *** samsagaz has quit IRC | 03:16 | |
| CarlFK | are all of the fupy's all lm32? | 03:27 |
| CarlFK | circuitpython danh says "we make that assumption a lot of places. (little-endian) we assume stack grows down, etc." | 03:34 |
| xobs | I haven't tried fupy with vexriscv yet. And my setup isn't designed for xip at the moment. I should give it a shot though. | 03:35 |
| CarlFK | shucks. one of the CP devs is in town for another 2 days. I was hoping for "let me show you CP running on an fpga" but I don't think that's going to happen | 03:40 |
| cr1901_modern | Little endian is a very short-sighted assumption. :/ | 03:54 |
| cr1901_modern | And the truth is, fupy is most stable on lm32. I had to do some horrifying things to get picorv32 to work. | 03:54 |
| cr1901_modern | (not endian related) | 03:55 |
| cr1901_modern | well, ummm, the micropython problems aren't endian related; other issues certainly were :) | 03:55 |

| CarlFK | cr1901_modern: is there a list of what soft cores fupy builds on? | 04:07 |
| cr1901_modern | lm32 and picorv32 | 04:09 |
| cr1901_modern | and well prob vexriscv, but I've not had much luck | 04:09 |

| CarlFK | mithro: have you seen http://www.fourwalledcubicle.com/LUFA.php "open-source complete USB stack for the USB-enabled Atmel AVR8" | 21:27 |
| tpb | Title: Four Walled Cubicle - LUFA (Formerly MyUSB) (at www.fourwalledcubicle.com) | 21:27 |
| CarlFK | im guessing you are working on the "USB-enabled" bit for the fpga ? | 21:28 |
