| cr1901_modern | mithro: Why is .bss in firmware/linker.ld placed in main RAM? | 02:39 |
|---|---|---|
| cr1901_modern | err, SRAM* | 02:40 |
| cr1901_modern | Shouldn't everything be placed in main RAM since that's what we have access to by the time HDMI2USB boots? | 02:40 |
| cr1901_modern | Just for testing purposes, I'm going to put "__attribute__ ((section ("main_ram")))" on the bitbang and bus buffers | 02:42 |
| * cr1901_modern feels dirty using a gcc extension | 02:42 | |
| mithro | cr1901_modern: I think we place stuff in SRAM because of legacy reasons -- a while back the CPU would lock up if you tried to read/write from the DDR while DMA operations were happening | 03:21 |
| mithro | I believe _florent_ fixed that problem a long time ago.... | 03:21 |
| cr1901_modern | mithro: Is there a define to indicate we are executing within qemu-litex when compiling (I'll need one to create a working timeout for qemu-litex since the timer is broken) | 03:41 |
| cr1901_modern | Current status is: xmodem impl passes tests but crashes early on when I try running it from the firmware :/. The serial wrapper provided by libmodem works outside of the xmodem_rx function. Investigating now. | 03:42 |
| mithro | No and probably a bad idea to enable - much better to fix the timer support in qemu-litex :-P | 03:42 |
| mithro | cr1901_modern: If the timer is blocking your work, I can try and take a look at fixing it... | 04:09 |

| mithro | cr1901_modern: You're not trying on real hardware? | 05:38 |
| paddatrapper | mithro: do you mind having a look at the set_interface issue on the opsis? My latest blog post describes where it seems to be coming from | 06:24 |
| mithro | paddatrapper: I'll try and get to it this evening, can you ping me again in ~3-4 hours? | 06:26 |
| paddatrapper | mithro: sure | 06:28 |
| *** twoolie has quit IRC | 07:36 | |
| mithro | paddatrapper: poke me in about an hour. | 09:03 |
| mithro | paddatrapper: do you also want to have a VC and sync up about your progress? | 09:04 |
| mithro | Ishan_Bansal: ping? | 09:04 |
| Ishan_Bansal | mithro : pong | 09:14 |
| mithro | I will be around in about 1-2 hours, can you be around so that we can go through the process of getting all your stuff merged? | 09:15 |
| Ishan_Bansal | mithro : I have a class after 2 hours. | 09:15 |
| Ishan_Bansal | The class is probably for 1 hour before and after I am free. | 09:17 |
| paddatrapper | mithro: I'm currently in very dodgy cell reception, camping with my dad so VC would be difficult | 09:54 |
| mithro | Ishan_Bansal: okay | 10:19 |
| *** twoolie has joined #timvideos | 10:19 | |
| paddatrapper | mithro: poke about the set_interface | 10:25 |
| mithro | paddatrapper: Okay, just eating dinner :-P | 10:25 |
| paddatrapper | No problem | 10:25 |
| mithro | paddatrapper: So what should I be reading? | 10:48 |
| *** rohitksingh has quit IRC | 10:54 | |
| paddatrapper | mithro: my latest blog post | 11:01 |
| paddatrapper | The issue is if I try and ISO packets, it fails to set interface when switching to the ISO streaming interface. I think it gets stuck in an infinite loop | 11:02 |

| cr1901_modern | mithro: "cr1901_modern: You're not trying on real hardware?" No, I've been trying on real hardware. There were some... bugs w/ the serial wrappers I wrote for litex in my library (b/c I churned them out quickly b/c I wanted to test, rather than carefully studying them). In any case, xmodem _xfer_ is working successfully now. | 23:14 |
| cr1901_modern | (still working on actually writing to flash w/ xmodem results, but that's trivial) | 23:14 |
| cr1901_modern | "but that's trivial" Watch me eat those words... | 23:15 |
| mithro | :-P | 23:30 |
| mithro | cr1901_modern: I'll be around in a couple of hours | 23:46 |
| cr1901_modern | mithro: Ack | 23:50 |
