| _Bnu | Yeah, though it's being reworked so individual bytes of the address lines can be set to save time. | 00:00 |
|---|---|---|
| _Bnu | And so that the IPL lines can be sampled directly. | 00:01 |

| CottonUndies | In one or two sentences can someone describe the audio add-on that is being considered? I saw the new twitter post with the new IN/OUT2 label, but in total I'm still not sure what I'm looking at, I do believe however that this will enable accelerated MHI (?) output over the OUT1 port? I guess anotther thing I should note is that while audio over HDMI is ok, I really need good analog or digital out, nothing to to with HDMI | 16:20 |
| CottonUndies | . Maybe I just don't understand the concept.... | 16:20 |

| apolkosnik[m] | Is that how hdmi packages audio? | 18:02 |

| mntmn | _Bnu: in the rtg of pistorm, do you offer 24/32 bit only or did you implement a trick for 8/16 bit somehow? does it do 8 bit? | 22:18 |
| mntmn | (color i mean) | 22:18 |
| mntmn | i guess 8bit LUT color could be done with a shader? | 22:30 |
| mntmn | ah i just watched a youtube vide of one dude setting up pistorm, and he had an 8bit mode. now i'm curious how it is implemented | 22:58 |
| mntmn | ah yeah a shader alright https://github.com/captain-amygdala/pistorm/blob/main/platforms/amiga/rtg/clut.shader | 23:05 |
| mntmn | i should really try out my pistorm to see what you've been up to! | 23:18 |
| isoriano_ | mntmn: Just one question .. those are Samtec connectors on the ZZ, right? | 23:18 |
| mntmn | isoriano_: i think so, why? | 23:19 |
| isoriano_ | ZZ for Sun | 23:19 |
| _Bnu | mntmn: 8-bit is done using a shader, yeah. | 23:20 |
| mntmn | btw i think i might make an adapter from ZZ9000's main board to an ECP5 + CM4 thing | 23:20 |
| mntmn | like, fpga->cm4 | 23:21 |
| mntmn | all other solutions seem either underpowered or massively overpriced | 23:21 |
| _Bnu | For RGB565, the Pi GPU doesn't support BE 565, so I have to flip all the bytes manually before uploading the frame buffer to texture, haha. | 23:21 |
| mntmn | ha! | 23:21 |
| _Bnu | For the Pi 4, I'll also have to make an RGBX8888 swizzle shader. | 23:22 |
| mntmn | _Bnu: btw i watched this video, skipped through some parts but it gave me an impression! https://www.youtube.com/watch?v=ZnKQYWEbEvM | 23:22 |
| mntmn | it was kinda wholesome | 23:22 |
| _Bnu | Because for some reason they dropped support for the one P96 uses by default. | 23:22 |
| mntmn | schwizzle | 23:22 |
| _Bnu | And if you use the other one, P96 flips all the bytes in software... on the 68k... | 23:22 |
| mntmn | ah i see! | 23:22 |
| mntmn | lol | 23:22 |
| isoriano_ | mntmn: this one please :-) https://shop.trenz-electronic.de/en/30631-MYC-CZU3EG-CPU-Module-with-4GB-DDR4-128MB-Flash-Ethernet-USB | 23:23 |
| mntmn | isoriano_: too expensive | 23:23 |
| mntmn | doesn't make sense if you look at the price of the cm4 | 23:24 |
| mntmn | and i can put the bus glue and the capture in a lower priced fpga | 23:24 |
| + RobDangerous (~Thunderbi@p200300ec8f00de0089a877ff9ee0a465.dip0.t-ipconnect.de) | 23:24 | |
| mntmn | speaking of capture... Claude did some denise -> MIPI CSI thingie right? how did that work out? | 23:25 |
| mntmn | alternatively i could give the fpga its own sdram buffer and use the code from va2000 and put a HDMI switch in there, but it seems overkill perhaps | 23:27 |
| _Bnu | Ah, as far as I know it works, but I haven't gotten to try it out yet. | 23:27 |
| _Bnu | The stuff in the github repo for it needs some setup that I don't yet know the details for, haha. | 23:27 |
| mntmn | oh TMDS251 is only like 2.50 eur | 23:28 |
| _Bnu | It works as a Denise passthrough though, that much I can confirm...! | 23:29 |
| mntmn | alright! | 23:29 |
| mntmn | argh but we have the sii chip on the zz9000 carrier | 23:30 |
| mntmn | so it might make more sense to redesign zz9000 and put the cm4 on it directly | 23:30 |
| mntmn | but then it's not a nice upgrade for existing users | 23:30 |
| mntmn | many question marks :3 | 23:30 |
| _Bnu | ZZSCSI...! | 23:31 |
| _Bnu | I can make a really horrible boot ROM for it... | 23:31 |
| mntmn | yeah anyway i want to improve the drive situation and also have autoboot and stuff | 23:31 |
| _Bnu | Ah yeah, and with the CM4 you could keep disk images on attached storage too. | 23:32 |
| mntmn | that's also possible with the zynq, for example on an usb stick | 23:32 |
| mntmn | and linux fw | 23:32 |
| mntmn | the mythical, not delivered linux fw | 23:32 |
| _Bnu | Could probably reuse a lot of the PiSCSI code for both options. | 23:32 |
| mntmn | that is nice. | 23:33 |
| mntmn | the hdmi port conundrum could be circumvented with an additional slot bracket | 23:34 |
| mntmn | so there could be a zz9000 upgrade as well as a zz9000+ where this is more streamlined or something | 23:34 |
| mntmn | naja naja much food for thought | 23:34 |
| _Bnu | Wurst! Wurst! Wurst! | 23:35 |
| mntmn | all that wurst yes | 23:35 |
| _Bnu | Possibly turkey bacon... | 23:35 |
| mntmn | zz9001 | 23:35 |
| mntmn | (it's over 9000) | 23:35 |
| mntmn | ok i'm really gonna go home now. ' | 23:35 |
| mntmn | n8n8n8 | 23:36 |
| _Bnu | o/ | 23:36 |
