Abstract	Cov ntaub ntawv no piav qhia txog yuav ua li cas rau chaw nres nkoj PN7160 / PN7220 cov khoom nruab nrab tso tawm rau Android 14.

Phau ntawv qhia no muab cov lus qhia ntxaws txog yuav ua li cas koom ua ke NXP NCI-based NFC controllers, PN7160 thiab PN7220, rau hauv ib puag ncig hauv Android. Cov txheej txheem suav nrog kev txhim kho cov neeg tsav tsheb tsim nyog thiab kev teeb tsa ntawm MW (saib [1]). Yog xav paub ntxiv, xa mus rau nplooj ntawv khoom rau PN7160 [2] thiab PN7220 [3]. Lub Android Open Source Project (AOSP) tau hloov kho los koom nrog kev txhawb nqa rau PN7160 thiab PN7220 NFC cov tswj hwm.

PN7220 los ntawm ob qho kev teeb tsa: ib leeg-tus tswv thiab dual-tus tswv. Cov pawg feem ntau yog tib yam rau ob qho tib si. Hauv hom dual-tus tswv tsev, SMCU tau ntxiv uas txhais tau hais tias tag nrho EMVCo cov haujlwm ntsig txog raug ua tiav ntawm SMCU. Hauv singlehost EMVCo raug tua hauv EMVCo MW pawg

Kernel tsav tsheb

Txhawm rau tsim kev sib txuas nrog PN7220 lossis PN7160, pawg hauv Android siv nxpnfc kernel tsav. Nws tuaj yeem pom hauv [4]

Cov ntaub ntawv tsav tsheb

PN7220 txhawb nqa I2C lub cev sib cuam tshuam, thaum PN7160 txhawb nqa I2C lossis SPI lub cev sib cuam tshuam. Thaum ntsia rau hauv lub ntsiav, tus tsav tsheb raug nthuav tawm ntawm lub cuab yeej node hauv /dev/nxpnfc.

Nco tseg: PN7160 thiab PN7220 siv ob tus tsav tsheb sib txawv, xaiv tus tsav tsheb kom raug raws li hom nti.

Tau txais PN7160 tus tsav tsheb qhov chaws

Luam the nfcandroid_platform_drivers/drivers/pn7160/nfc driver repository to the kernel directory, hloov cov kev siv uas twb muaj lawm. Xa mus rau [4] rau lub kernel files.

$rm -rf drivers/nfc
$ git clone "https://github.com/nxp-nfc-infra/nfcandroid_platform_drivers.git" -b

Tsim tus tsav tsheb

Lub devicetree yog lub luag haujlwm rau ntxiv tus tsav tsheb rau lub ntsiav thiab thauj khoom ntawm lub khau raj ntaus ntawv.

Tom qab kev kho dua tshiab ntawm devicetree specification, lub platform-txog devicetree yuav tsum tau rov ua dua. NXP pom zoo siv kernel version 5.10 vim nws muab kev lees paub dav dav.

Txhawm rau tsim tus tsav tsheb, cov kauj ruam hauv qab no yuav tsum tau ua:

1. Tau tus neeg tsav tsheb kernel
2. Tau qhov chaws code rau tus tsav tsheb
3. Hloov kho lub devicetree txhais, uas yog tshwj xeeb rau cov cuab yeej siv.
4. Tsim tus tsav tsheb:

ib. Los ntawm cov txheej txheem menuconfig, ntxiv lub hom phiaj tsav tsheb rau hauv kev tsim.

Tom qab rov tsim kho cov ntsiav ua tiav, tus tsav tsheb yuav raug suav nrog hauv daim duab kernel. Tag nrho cov duab kernel tshiab yuav tsum tau theej rau hauv AOSP tsim.

AOSP adaptation

NXP ntxiv kev hloov kho rau AOSP code. Qhov no txhais tau hais tias AOSP code yog siv los ua lub hauv paus, tab sis txuas ntxiv rau NXP cov yam ntxwv tshwj xeeb. [5] yog AOSP tam sim no tag siv los ntawm NXP. Tom qab tau txais AOSP tsim, AOSP code uas twb muaj lawm yuav tsum tau hloov, thiab ntau thaj ua rau thaj yuav tsum tau siv.

Nco tseg: Ib qho txawv version ntawm AOSP code tuaj yeem siv tau, tab sis yuav tsum tau ua cov kev hloov kho ntxiv.

AOSP tsim

Tau txais AOSP qhov chaws code.

$ repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r2 $ repo sync

Nco tseg: Cov cuab yeej repo yuav tsum tau muab tso rau hauv qhov system. Xa mus rau [6] rau cov lus qhia.

Tsim qhov chaws.

$cd Android_AROOT
$source build/envsetup.sh
$ pluas su select_target #target yog DH peb xav siv rau example: evk_8mn-userdebug
