Dears

I'm trying porting PN7150 to rockchip 's rk3326 platform , which runs android oreo 8.1

I have followed steps of AN11690 , and merged rockchip's source with GitHub - NXPNFCLinux/nxpnfc_android_oreo: Android patches for support of PN7150 NCI based NXP NFC Co... 

Then, I faced some issues which are not mentioned in AN11690 document.

hal_nfc_default  sepolcy coredomain assiociated build error

later , i added hal_nfc_default in treble_sepolicy_tests.py's coredomainWhilelist  to solve this issue.

Then compiled and run the firmware into board.

It has a runtime error of NFC hwbinder,  it can't find INfc/default interface of  manifest.xml

Afterward i add related INfc /default tag in the patch of manifest.xml to solve it

And AN11690 Step 3.1.5  doesn't mention the interface tag  should be added

After this patch ,  Android's Setting have NFC option , but it is not worked still.

The newest issue  is about   vndk sphal  can't load   android.hardware.nfc@1.0-impl,so 

but   android.hardware.nfc@1.0-impl,so  is actually located in /vendor/lib64/hw/

Is there any one also experienced porting nxp nfc to android oreo?

Hi,

You should fix your issue by making sure that you've added the service and it is running. Here is my {board}.mk file:


# NXP NFC support
PRODUCT_PACKAGES += \
NfcNci \
Tag \
com.nxp.nfc \
android.hardware.nfc@1.0-impl \
vendor.nxp.nxpnfc@1.0-impl \
vendor.nxp.nxpnfc@1.0-service \
nfc_nci.pn54x

# Add custom NFC files
PRODUCT_COPY_FILES += \
frameworks/native/data/etc/android.hardware.nfc.xml:system/etc/permissions/android.hardware.nfc.xml \
frameworks/native/data/etc/android.hardware.nfc.hce.xml:system/etc/permissions/android.hardware.nfc.hce.xml \
frameworks/native/data/etc/android.hardware.nfc.hcef.xml:system/etc/permissions/android.hardware.nfc.hcef.xml \
device/{venodr}/{board}/nfc/libnfc-brcm.conf:$(TARGET_COPY_OUT_VENDOR)/etc/libnfc-brcm.conf \
device/{venodr}/{board}/nfc/libnfc-nxp.conf:$(TARGET_COPY_OUT_VENDOR)/etc/libnfc-nxp.conf \
device/{venodr}/{board}/nfc/libnfc-nxp_RF.conf:$(TARGET_COPY_OUT_VENDOR)/libnfc-nxp_RF.conf

PRODUCT_DEFAULT_PROPERTY_OVERRIDES += \
ro.hardware.nfc_nci=pn54x

Best regards,

Dear Nikolaos:

Thanks for your kindly help .

Although I have done all the changes you mentioned already ,  the final issue still continue  print as the error log as the last screenshot.

"Could not load....... from sphal namespace"

Then i tried to trace source , it is related to libhidl/transport/ServiceManagement.cpp  .

My android.hardware.nfc@1.0.so has always been load as sphal library.

,then i change "if (path != HAL_LIBRARY_PATH_SYSTEM) " to if(0) and let it always run "else" condition--> "dlopen(fullPath.c_str(), dlMode);"  .

After this modification , Nfc /pn54x  works .

I think  NXP should refine the patch document  , depend on different platform , It usually needs additional modification to make it works

Hi Hanny,

Sorry but I cannot think of anything. So, you cannot see any obvious crash and the NFC HAL has all the appropriate permissions to access the nfc device? Can you please make sure that the 'nxpnfc_hal_svc' is starting only once, because it looks like something else is setting a value on the "ro.boottime.nxpnfc_hal_svc".
