Thanks. Just to clarify, the small connector on the board isn't mSATA. Its actually M.2 SATA, which is considerably more common these days. Since converting from 2.5" SATA to mSATA or M.2 SATA with a small adaptor board, you can easily use either another mSATA or M.2 SATA SSD, with a very...
@Brooklyn It sounds like one or more of your ZuluSCSI boards may be operating in "raw passthrough" mode. If that's the case, the LED on the ZuluSCSI will blink three times upon initialization (to indicate it didn't find a valid image file OR filesystem).
Currently, the only way to change the...
Also, if the enclosure has its own SCSI termination, you may have a situation where you're double-terminating the bus without realizing it. If there's termination provided by the enclosure, you would want the termination on the ZuluSCSI itself to be OFF.
In that case, you should probably report it at https://github.com/ZuluSCSI/ZuluSCSI-firmware/issues
Please include a copy of the zululog from the device (when it detects the SD card) as it will contain answers to some of the most basic questions we'd otherwise have to ask.
Is it the only...
Hi @WarriorRocker, did you ever get this sorted? It looks like you don't have SelectionDelay=0 set. I just confirmed on my Mac Plus that it must be set before it will boot. You also need to have EnableSelLatch set to 1:
[SCSI]
EnableSCSI2=0
EnableSelLatch=1
SelectionDelay=0
@dramirez adding a supercap there willresult in the thermal fuse, F202 tripping, due to the inrush of current caused by the presence of the supercapacitor in the circuit. Without additional circuitry to manage that inrush, your board will just appear to have died, until the fuse cools off and...
There isn't, and here's why....the microcontrollers used with ZuluSCSI are limited to ~1MByte/sec (USB Full Speed), not USB High Speed. If you want to add the ability to access files via USB, the firmware is open source. We accept pull requests :)
On the ZuluSCSI PCBs, the names of the J303 expansion headers are silk-screened on the bottom of the ZuluSCSI PCBs. With that information, you can refer directly to the relevant datasheets for the GD32F205.
The full-sized ZuluSCSI RP2040, having only 56 pins, as opposed to the GD32F205's 100...
@jmacz and @tcole , please try the nightly build from https://github.com/ZuluSCSI/ZuluSCSI-firmware/releases/tag/latest which should fix the CD-ROM unmounting on reboot issue.
Thanks. I've wanted something like this for my own personal use for a while, and I'm glad you and others are also excited about it.
As others have already noted, it's a simple matter of not owning the intellectual property. I'd love to be able to license it, but there are numerous barriers to...
We've been doing testing on this, and, overall, compatibility seems good. There are a couple of notable, widely-available low-end SSDs (WD Blue, with the SanDisk-branded SATA controller) which fall over HARD when writes are attempted. Reads work fine, though, which is interesting.
Correct, no ROM is needed under Windows, _if_ you don't need to boot from it, although you'd still need a suitable SiI3112 driver. The Silicon Image reference PC boot ROM is available via archive.org, from the original Silicon Image website.
This is part of why we chose to _not_ use the generic Chinese cards as a starting point, even though it would have been easier, and less costly, to do. Those designs are just too cost-reduced, in our view. Here's the relevant section of the schematic from the reverse-engineered Adaptec...
This is where Mac-on-Linux comes in. It also provides convenient display and audio driver abstraction layers. I'm also not sure you're correct in the assertion that _all_ embedded PowerPC CPUs are this way. The e300c3 core is _not_ Book-E, which is what I believe you're referring to.
