I am testing my new custom board with PN5190 integrated similarly to PNEV5190 (EVB).
It seems to work OK with the integrated DC-DC, I can use LPCD and read tags and all.
Now I am trying to setup the ULPCD, so I have connected VUP_TX to VBATPWR, and I get an error when trying to calibrate. I guess it might be the same error shown here but not sure how to overcome this programatically.
The raised error is as follows:
PN5190 Booted correctly -DEBUG-: [Thu Jan 1 00:00:00 1970] phDriver_PinConfig ( 34 ) -DEBUG-: [Thu Jan 1 00:00:00 1970] Install gpio isr service for gpio ( 34 ) -DEBUG-: [Thu Jan 1 00:00:00 1970] MIFARE key update... -DEBUG-: [Thu Jan 1 00:00:00 1970] NFC init as ULPCD ULPCD => 2x Calibration once => x2 LPCD calib...

Refer-ph_Status.h ULPCD Calibration Failed. Line: 588 Error - (0x027F) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h NFC Calib error !
As you can see the HF attenuator value is read (bHFATT_Val (0x11)) during calibration.
VDD_BOOST remains connected to VUP_TX, so it is the same as the EVB.
Can anyone help on this?
