| CottonUndies | @mntmn You have a Warp Engine in a A3000? Two SIMM slots? If yes, can you please check to see if the memory is confirmed in one or two chunks? In my system I cannot get the 64meg ram to be contiguous. | 11:39 |
| mntmn | CottonUndies: 4 simms | 12:36 |
| mntmn | CottonUndies: i use the A4000 version and sawed off part of the connectors to make it fit | 12:37 |
| mntmn | brutal | 12:37 |
| mntmn | CottonUndies: so i have 128 meg from it | 12:37 |
| mntmn | _Bnu: i agree, also totally possible with an SPI cable or something | 12:38 |
| mntmn | pci express over fibre channel | 12:38 |
| _Bnu | >:3 | 12:54 |
| Claude | _Bnu is running wild! befruchten all the Amiga opensourcen | 13:17 |
| Jope | a rampant bnu | 13:18 |
| Claude | mntmn: usb? Pi3a can act as 480mbps usb device | 13:40 |
| mntmn | Claude: also not bad! but then you have 2 usb stacks in there... | 13:42 |
| mntmn | latency this that | 13:42 |
| Jope | raspi3 has a pcie bus on it too doesn't it | 13:42 |
| Jope | or was it raspi4 | 13:42 |
| Jope | I remember a project where someone took out the usb controller from a raspi and connected to the pcie bus left behind | 13:43 |
| Claude | pi4 | 13:43 |
| mntmn | from 2012: > The Raspberry Pi SPI runs at APB clock speed, which is equivalent to core clock speed, 250 MHz. This can be divided by any even number from 2 to 65536 for the desired speed. The datasheet specifies that the divisor must be a power of two, but this is incorrect. Odd numbers are rounded down, and 0 (or 1) is equivalent to 65536. A divisor smaller than 2 is therefore impossible | 13:43 |
| mntmn | Jope: yeah but that's a huge ugly hackjob. the cm4 can give you a pcie port | 13:43 |
| Claude | yeah 64MHz is Ende Befruchtung | 13:43 |
| Claude | on SPI | 13:43 |
| Jope | mntmn, oh yeah absolutely :-D I wouldn't really consider it for anything serious | 13:44 |
| Claude | 8MB/sec | 13:44 |
| mntmn | Claude: i see... how many lanes can be combined ;) | 13:44 |
| Claude | how many gpio are accessible ? :) | 13:44 |
| mntmn | ah > SPI Dual Mode is not supported on Raspberry Pi, and is rarely supported in general. You may find other micro-controllers that support Dual or Quad SPI (QSPI) | 13:44 |
| mntmn | Claude: oh yeah just a parallel gpio bus might be faster | 13:45 |
| mntmn | Claude: see here https://mntre.com/media/ZZ9000_info_md/zz9000-manual-r3.pdf | 13:45 |
| Claude | I could bitbang dspi,qspi,ospi up to 60ish MHz | 13:45 |
| Claude | ospi as in 8bit parallel with clock :) | 13:46 |
| mntmn | Claude: 10 GPIOs on expansion port and a bunch of MIO pins | 13:46 |
| Claude | I have a rev1 | 13:46 |
| mntmn | Claude: doesn't matter, the expansion port was never changed | 13:47 |
| mntmn | only audio stuff was changed later | 13:47 |
| Claude | phew :) great , couldn't arse myself to open the a3000 | 13:47 |
| mntmn | Claude: so we could do 8pin parallel | 13:47 |
| Claude | ok 10 GPIOs , mit bad ! | 13:47 |
| Claude | not | 13:47 |
| mntmn | Claude: here's the R1 https://mntre.com/media/ZZ9000_info_md/zz9000-manual.pdf | 13:47 |
| Claude | but what can we do then ? for the 68k emulation I need all pins :/ | 13:48 |
| mntmn | Claude: ah, but that's not my fault!!!1112 | 13:48 |
| Claude | haha | 13:48 |
| Jope | are you guys scheming a zz9000 <-> pistorm interface :-) | 13:49 |
| mntmn | Jope: apparently the pistorm doesn't have any gpio!!12 | 13:49 |
| Jope | hehe it has lots! ;-) | 13:49 |
| Claude | ft232h or fx2lp connected to the pi ? 8bit sync FIFO should do 20-30-40 mb/sec easily | 13:49 |
| mntmn | Claude: can't we just sub-modulate something on the regular bus | 13:49 |
| mntmn | in the band gaps... | 13:49 |
| Jope | 68kbusio hehe | 13:49 |
| Claude | with a FX2LP I captured Amiga video already from the pi :) | 13:50 |
| mntmn | btw nobody says how you have to behave inside of a zorro transaction right... | 13:51 |
| Claude | latency is yeah usb .. but I don't think that pixels get one by one that often :) so it's bursty | 13:51 |
| mntmn | so you could do bursts inside of a zorro transaction | 13:52 |
| mntmn | over the regular bus | 13:52 |
| Claude | true , but I have no real idea about Zorro and how .. | 13:52 |
| Claude | hmm | 13:52 |
| mntmn | naja naja | 13:53 |
| Claude | like the pic doesn't acknowledge the transfer on Zorro and while the pic still holds the bus ownership bursting data ? | 13:53 |
| mntmn | yes | 13:54 |
| Claude | like playing a real slow Zorro card | 13:54 |
| mntmn | yes | 13:54 |
| mntmn | "we're gonna take a while here" | 13:54 |
| Claude | might work | 13:54 |
| mntmn | depends a bit on how noisy and slow those bus lines are | 13:54 |
| Claude | but I have no idea on how much the Amiga Chipset will interfere with that | 13:55 |
| Claude | like buster or whatever gets upset | 13:55 |
| mntmn | buster getting ~very~ angry!! | 13:55 |
| Claude | sounds like a plan! | 13:55 |
| Claude | from the feeling I would say usb is a feasible way , using e.g. a ft232h in sync FIFO on the 10 GPIOs | 13:57 |
| Claude | ftdi states 40MB/sec for that | 13:58 |
| Claude | not enough Io :( | 14:00 |
| Claude | ft1248 on ft232h in 4bit mode would fit then | 14:03 |
| _Bnu | Hahah. | 16:54 |
| _Bnu | You can hold up the bus for a pretty long time without the computer dying at least. | 16:55 |
| _Bnu | But yeah, even inventing a little USB protocol to say hello to the ZZ9000 and sending blobs of data/commands to it would probably work wonders. :D | 17:02 |
| _Bnu | (Suddenly better bandwidth available to/from the card on Zorro II than III. ;D) | 17:10 |
| _Bnu | Could even add a mapped memory range on the PiStorm to offer sort-of AXI DMA on an A500/A2000. | 17:11 |
