Thanks with your brilliant work and PoC.

Somehow, when I was trying to run perform the sniffing on a Infineon SLB96350, I cannot receive any data. It just stuck on [*] Start sniffing.

The LED on iCEStick is always in red, not blinking all the time.

Then I double checked that opio is enabled on channel B, also I could flash the board with compiled bitstream and got a SUCCESS message.

I have seen some related issues with TPM 1.2 on other lpc-sniffer based project, maybe something is messed up when dealing with old TPM standard?

Sorry for my bad English and thanks again.

Brilliant work! Unfortunately I am not able to get it working with ST19NP18-TPM which is built-in in a Lenovo W520, also V1.2...

The Icestick is not blinking a single time, Saleae shows me the signals (see https://www.dropbox.com/s/ivrs4a5sng3uk3l/Lenovo_W520_LPC.sal?dl=0)
What could possibly be wrong/not working?
