| mithro | futarisIRCcloud: That board was released at the TensorFlow summit a while back? | 00:38 |
| xobs | futarisIRCcloud: yep! Solved the problem. Now the only outstanding issue is dfu needs fixing. But that's a C issue. | 00:39 |

| mithro | xobs: How goes Fomu thins and were in the world are you these days? :-P | 00:43 |
| xobs | mithro: I have an update queued. | 00:45 |
| mithro | xobs: Bunnie's patching videos looked cool :-P | 00:46 |
| xobs | I screwed up dvt1, yeah, but now my patches are validated so I placed a purchase order for DVT2. | 00:47 |
| xobs | ...which might become pvt1 | 00:47 |
| xobs | Next week will be work on the case. | 00:47 |
| mithro | xobs: Did you see the email from the Solokey people? | 00:48 |
| xobs | I expect to have an MVP Fomu dfu bootloader done this week. Finally. | 00:48 |
| mithro | xobs: Great | 00:48 |
| xobs | And I'm in Hong Kong today and tomorrow. Busy busy. | 00:48 |
| xobs | mithro: I did see the email. I also need to respond to that. | 00:55 |
| mithro | You should probably forward the crowdsupply announcements to the tomu-discuss mailing list? | 00:56 |

| tnt | xobs: btw, I think it was in your ccc talk about the arm usb stack that you mentionned that not caring about the address field was fine. I found at least one hub where this fails. Device works fine but no new device can be connected to the hub afterward. | 13:11 |
| xobs | tnt: I could see that being the case for broadcasts, but the device never actually creates any packets with the address field. | 13:40 |
| xobs | Also, most FS/LS devices connected to a USB HS hub will go through a TT. | 13:41 |
| tnt | yeah of course, but my guess is the hub just broadcast the enumeration with addr 0 to all its ports or something ... | 13:41 |
| tnt | tbh I didn't dig much deeper than "answering to all packets regardless of addr" seemed to cause issue in that particular case :p | 13:42 |
| tnt | might be worth putting an analyzer on there. | 13:43 |

| xobs | tnt: I do, why do you ask? | 14:33 |
| tnt | Just wondering how small the vexriscv can be. I guess the cache doesn't come for free and if the app runs out of spram purely, that shouldn't matter right ? (I assume cache is mostly if XIP from flash ?) | 14:34 |
| tnt | huh 2-stage-no-cache-debug.v == 2-stage-1024-cache-debug.v ? | 14:35 |

| xobs | Is it no flash? I thought it had cache. I might have screwed up the naming. | 14:37 |
| xobs | That's the Makefile that I'm using to create the various versions of the CPU. | 14:37 |
| tnt | the verilog files for the 1024-cache and no-cache version are the same. | 14:38 |

| poranek | Hello | 16:26 |
| poranek | Is possible increase memory? | 16:26 |
| poranek | mruby need 400kB memory for running. | 16:27 |
| poranek | mruby have many constans variable and big flexible compiler | 16:27 |
| poranek | on fomu | 16:30 |
| tnt | no | 16:41 |
| tnt | The FPGA has 1 MBits SRAM (i.e. 128 kbytes), nothing you can do about that. | 16:41 |
| poranek | ;( Ruby are more flexible language ;) | 16:41 |
| tnt | if this is 'static data', you can possibly use flash. | 16:42 |
| poranek | flash are separately? | 16:42 |
| tnt | and XIP (eXecute In Place) | 16:42 |
| tnt | yes, the flash is a separate chip, but for the purpose of a CPU it's pretty much read-only memory. | 16:42 |

| poranek | is possible using tomu as koprocessor? | 18:34 |
| poranek | for example i put it to raspberry pi and can learn network artifical | 18:34 |
| tnt | the tomu or fomu ? | 18:38 |
| poranek | You tell me | 18:41 |
| poranek | for example my C program can put data and run program on fomu/tomu? | 18:46 |
| poranek | can You show/tell me any example? | 18:46 |
| tnt | nope sorry. never used either of them. | 18:47 |
| poranek | You dont use C? | 18:49 |
| poranek | I'm not undestand | 18:52 |
| poranek | ok | 18:59 |
