So; it's so.

GB TR 2.0 arrives next Wednesday!

I have already received my KeeYees ch341a, and have been practicing on a few un-essentials around the house.

The KeeYees is not recognised by BS/Monterey (unless I re-boot with it attached (*and* connected to a chip!)); so, I attached it to my PI 4b, and used flashrom 1.0-1

Quadro FX 580: ATMEL918 25F512AN SU27 (never recognised after many, multiple tries)

ASUS Laptop (D550C)): WinBond 25Q(O?)C4FVSIG 1324 (after multiple tries, nothing; then (only once!) it received, and I was able to dump the .bin (no successful connection on multiple re-tries))

I really don't want to buy another of these cards, and (since I will be doing the same process with (probably) the last WX7100 1.1 on the planet) I really don't want to fsck anything up ;)

I understand that connection/reading of a Chip is non-destructive, but my initial tests have left me wanting.

Should I keep the bog-standard chip-clip, or order a Pamona (as seems to be the recommendation in online comments)?

Still, very exciting....

While many have had success using the CH341A unmodified, you may still want to err on the side of caution (to make sure that things are really kept nondestructive!):

A good USB hub can also fix that.

The standard clip is fine. I've used it extensively.

Good luck!

Oh, good: more R&R Love it :)

Oho! That will sure makes things a lot easier (pi's regularly on headless pi-hole duties).

What's 'good' in your book?

Very cool.

Thank you. I really appreciate the time you invest explaining all these things.

Well, I took a multimeter to it, and checked the v ... 5v on the data lines, as expected ;)

I'll give the by-pass a go; don't mind breaking a USD10 thingie, or two.

thx for the heads-up

[edit]

Ordered another USD13 ch341a kit in case I bjork the first one

Hi,

I have an issue with my presonus quantum 2626 connected to my Mac Pro mid 2020 with titan ridge 2.0 flashed card in it . The issue is with Big Sur, I have installed the latest universal controller from presonus and that works and quantum 2626 shows up in Big Sur with the proper 40 Kbs speed everything is fine but the sound is distorted there is an echo kind of sound a stutter and scratch sound so I can't use my interface with my daws. This is not the case with Mac OS X Catalina, it runs fine with that, I used open core 6.0 with that , I have to boot 2 x but that don't bother me non.

I would like to have it running with Big Sur also but unfortunately that does not work like I mentioned above.

Anyone any ideas, Does Martin Lo know maybe something about this issue

thanks in advance

hmm weird, sorry I don't really know what the issue is. You may have to roll back your OS, try to unplug then plug it back in while the computer is on to the other thunderbolt port and switch sample rates from 48k to 44.1 and then back 48k. I have to do that sometimes to wake up my board when its not showing up. Sorry can't be of more help.

Turns-out, since I decided to read the GC-TR 2.0 flash chips using my rPi 4b (derived from CaseySJ mini-guide), the only item I needed from either kit was the clip+wiring plugged into the 8-pin socket.

Once I determined which clip worked the best, reading both .bins was painless and quick (most of the time spent was in multiple reads, multiple shasum's and getting them to proper storage on the NAS).

With the GC-TB2.0 unflashed (TBC 1&3 jumped) installed, I can *almost* get 1 GB/s transfer speeds to my usb 3.1 gen2 ext. nvme attached to the StarTech 3.1 gen2 hub running off a TB port.

If it stays that way, I'm ok with it.

I'm going to take it nice and slow (more studying to do) before flashing a new .bin

[edit2]

ok, that's a no-go . . . GC-TR is effectively non-existent after re-boot, so no USB channels registered, at all.

Hi, i have an issue with my MP 5.1 with Mojave, Titan Ridge 2, Open Core and OWC Thunderbolt 3 dock....the mini display port won't recognized, I got my LED cinema hang on black screen, the dock is recognized from the system, the display through the dock not, any hint? thx in advance!!

Tested on my laptop, the mini display port from the dock works with the same display !

An interesting alternative that hasn't been mentioned before is the iMac19.2 Thunderbolt firmware:

Mac-63001698E7A34814-C0_6.84.0-C1_42.1-R0.bin

What's nice about this firmware is that
  1. it's from Apple and completely unmodified
  2. it's within 1 version of the v43 firmware for the GC-TITAN RIDGE
  3. the iMac19,2 has the same TPS65983 USB-C PD controller
I've confirmed that this firmware works (it can be flashed after padding with zeros to get 0x100000 bytes), but I don't have a lot of Thunderbolt hardware to determine that it's actually better than the modified v23 available in this thread. On the other hand, having extensively studied the Ridge firmware, I can say that the modified firmware files in circulation include several questionable modifications. In fact, a change of only three bytes is enough to get a working Mac-compatible firmware: 2 bytes for enabling Apple CM mode and 1 for disabling ARC...
Hello i use my titan ridge flashed with v23 firmware plus Ssdt with oclp 041

i Wanna try to flash my titan with this iMac firmware did you try it?

thanks

Hey Everyone! First of all, massive thanks to everyone for their work on this. I feel that I am achingly close to having thunderbolt on my MacPro 4,1 :)

I've got the card (Alpine Ridge V1) to register in system profiler with the full 40 Gb/s and I've got working and reliable USB 3.1. The issue is, I can't get a thunderbolt device to recognise at all.

I've tried a variety of different SSDT files & flashes of the rom to no avail. There was a suggestion that the Alpine Ridge card required 3.3V from an external source to activate it... But I'm not entirely sure if the card is already "activated" since it appears in system profiler correctly. Would love some expert opinions, especially for anyone who has gotten an Alpine Ridge V1 working?

Thanks in advance!

Specs:

MacOS Big Sur 11.6.1
Mac Pro 4,1 (flashed to 5,1)
Martin Lo's OpenCore (0.7.5)
Gigabyte Alpine Ridge (V1) - Flashed and pins jumped. Installed in slot 4.
Config attached - Saved as txt file so I can upload it.
maybe my experience will be useful:
This week I replace USB3 pcie card to thunderbolt Alpine Ridge (flashed).
I tried to install it with Martin Lo original config, turned on the SSDT,
of course the chipset was shown as Intel DSL7540, but Alpine Ridge should have 6540.
Nevertheless, i plugged in Belkin thunderbolt dock with connected thunderbolt RAID HDD,
did a warm restart - HDD doesn't show - in system info thunderbolt pci shown,
but in thunderbolt section disappeared. Then i changed settings in config and replaced SSDT-TBOLT3.aml
with SSDT-TBOLT3-AR.aml (Alpine Ridge SSDT provided by the card seller)- it works now.
I still need to test the work for a long time,
but I am not yet satisfied with replacing USB3 card with a thunerbolt card,
since after sleeping and waking up all devices disappear,
I need to turn off the CMP, boot the system, and then do another warm reboot.
Since I have a backup disk connected via thunderbolt to the Belkin dock,
and now it’s obvious that I won’t be able to make a recovery from time machines.
if I need to restore the system, I will have to put the backup disk inside the cMP.
Or did I something wrong with set up the thunderbolt card? and your cMP works differently?
ADDED after a whole day of testing:
I found that if I don’t use Belkin thunderbolt dock, but connect HDD devices directly,
then the work becomes more convenient -
I have one thunderbolt connected to WD MY Book Thunderbolt Duo -
in SysInfo it is shown as a thunderbolt device,
and the second to WD My Book Duo -
it is shown as USB 3.1 device.
When turning on or rebooting the cMP, external hdd are now shown.
And I can even make a recovery from an external time machine.
BUT IMPORTANT!
the disk that shows up as connected to usb 3.1 I can eject (using mac os eject command)
and reconnect again,
then if I try to disconnect the disk that shows up as a thunderbolt,
the system immediately crashes,
the cMP tries to reboot,
the GPU crashes - the display shows a damaged picture.
Neither reseting smc nor reseting nvram helps,
and the system boot freezes.
I found, that for some reason, EFI opencore is damaged.
Only a complete overwrite of the entire EFI returns the cMP to work (even without resetting SMC and nvram).
STILL IMPORTANT!
after sleep and wakeup, HDD is not visible again,
if I try to replug HDD,
the system immediately crashes and the result is the same as described earlier.
In order not to crash after the sleep and wakeup,
I have to turn off and boot the cMP with the devices DISCONNECTED from the thunderbolt,
and reconnecting again after the system boots.
And after a warm restart, then the hdd is visible again.
cMP works as usual, it can be turned off and after turning on the HDD are visible and working.
For me it is impossible to make any manipulations with connecting
and disconnecting devices while cMP is ON,
except for the procedure described above.
My question is, how does it happen that the EFI is damaged?
how to avoid it?
MacPro 4.1/5.1, dual 5680, Radeon Pro W5700, 96Gb samsung RAM, 1Tb nvme 970EvoPlus,
2TB Crusial P2, Alpine Ridge thunderbolt, OC 0.7.7, MacOS Monterey (Mojave, BigSur)

Try with This SSDT
Thank You, but I use it. My thunderbolt Alpine Ridge works with SSDT-TBOLT3-AR.aml from this build, but i have all issues, that I describe in my post. Thunderbolt Alpine does not work with SSDT from Martin Lo release, because it written for Titan Ridge, but Alpine Ridge has another chipset and another configuration.
