Hi Sheng,

Thanks for your email and response.

1. Yes I used unsigned binary - PSE_FW that came along with 638228_PSE

2. In Device Tree

 device pci 1d.0 off     end # Intel Programmable Services Engine IPC (local host to PSE)

 device pci 1d.1 on      end # Intel Programmable Services Engine Time-Sensitive Networking GbE 0
 device pci 1d.2 on      end # Intel Programmable Services Engine Time-Sensitive Networking GbE 1

3. This is not an RVP but a platform with EHL SoC and I could boot to OS/Ubuntu with coreboot BIOS

Do these TSN GbE devices need MAC programming? I don't see them enumerated from EFI Shell or in OS/spci

Thanks

Ranga

Hi Ranga,

Are you using Intel RVP? Yes you should at least be able to see the PSE TSN working if the PSE binary is included correctly (remember to include the 'unsigned' PSE binary from Intel), by turning on PSE TSN devices in devicetree.cb:
device pci 1d.1 on end # Intel PSE Time-Sensitive Networking GbE 0
device pci 1d.2 on end # Intel PSE Time-Sensitive Networking GbE 1

Thanks,

Sheng

Hi All,

Did anybody work on Elkhart Lake that comes with PSE Firmware?

I don't see any devices getting enumerated which are under PSE I2C,UART, Gbe,TSN 

The logs shows 

PSE Firmware Status is A138 read from address FE400034
BIOS: PSE FW is loaded and running

Looks like FSP is disabling PSE devices to enumerate

Is this binary enough for coreboot? PSE_FW.bin

Appreciate any pointers that would help to enumerate PSE devices in EFI Shell 

Thanks

Ranga
