Yep, I mentioned the standard API issue before... That opportunity was missed with the clockport, and as a result drivers have to probe the hardware themselves, with the potential to upset other hardware and drivers, and with things like clockport splitters having to be explicitly supported by the driver instead of simply attempting to open the clockport with a relevant unit number.
As for whether this interface would work with a clockport splitter, that depends on how the driver is written. It *should* work with a Prisma in most cases since the Prisma can be used on any port whereas non-splitter-aware drivers will only work on port 0. The only issue might be funky behaviour of either board from probing reads/writes of the other's driver. |

Excellent, great to see!
I too am very interested. |
Great project!
This will work on the clockport of a Deneb? If so, interested in three! |

Spidi what transfer rate you getting?
At the end of video you faded out just before that critical 'speed' test lol :) |
Speed is probably limited at ca. 100-150 kb/s in best case due to the clock port.
Still great I'd say. Take my money!!! ;) |

Test system - Amiga 1200 14MHz, 2MB Chip Ram, SPI controller for clock port. https://youtu.be/p47g-RUlOx4 |

Edit or sysinfo is being silly, let's find a reliable speed test tool and stick to it ? hmm |
Blimey, that SDHC makes a bit of a difference!
How many devices (CS lines) does the adaptor support? |
I would like to buy one of these too but to use in my a600 on the 604 expansions clock ports.

My SPI controller has a maximum clock of 25MHz. The same SPI controller in the Wicher500i card 50MHz shows a transfer rate of 48MB/s for any SDHC card and 250kB/s for a regular SD card. |

That looks very suspicious considering the speed of the clockport itself is a few 100 kbytes/sec.

Fortunately, it does not affect the correct operation of the driver with SDHC cards. |

Spidi, okay unsure then how this is happening or achieving greater performance than a couple hundred KB/sec without it being a bug. Are you faking the CRC's with 0xFF?
|
Any chance of an update ?
I'm craving to get one for Ethernet on my Miggy. :D |
