TL611 / TL631 debug cards not working on Z490 i higher chipset boards ?

[DynaxSC]

I have both of these chinese made debug cards, but they seem to work only on the Z390 family and older chipsets.

Does anybody know whats the reason for this ?

Are there any other debug cards out there working on Z490 - Z790 chipset families ?

Does not work anymore. So now it is harder to diagnose. Have to use onboard led. I had not seen any new debug card in china market.

Hi, I just made an completely astonishing discovery 😀!

The TL631 works on LGA1700 Gigabyte and ASUS boards the following way:

Gigabyte:

• the TL631 must be inserted into the las PCIe slot (farest from CPU) - using the short PCIe connector

ASUS:

• the TL631 must be inserted into the 5 pin com debug port as on the picture below - using the bigger LPC2 connector (pin 1 into pin 1):

I was looking how to do it for a long time, will not disclose for how long, because it's a shame 😁.

I confirmed this now on one Gigabyte Z790 UD and one ASUS PRIME Z690-P board, but most probably it will work also on other boards of these vendors.

This means that maybe there is also a way to use it also on other vendor boards, will have a look on it.

The older TL611 does not work on the ASUS PRIME Z690-P board, did not check it on the Gigabyte Z790 UD.

Let me know if anybody can confirm this, and if other vendors LGA1700 boards work.
