Tokomane ena e fana ka litataiso tsa ho kopanya molaoli oa NFC oa PN7220 NXP NCI sethaleng sa Android ho latela pono ea software.
E qala ka ho hlalosa mokhoa oa ho kenya mokhanni oa kernel e hlokahalang, ebe e hlalosa mohato ka mohato mokhoa oa ho iketsetsa mehloli ea AOSP ho eketsa tšehetso bakeng sa molaoli oa PN7220 NFC. Setšoantšo sa 1 se bonts'a meralo ea pokello eohle ea Android NFC.

Setšoantšo sa 1. Android NFC stack

PN7220 e arotsoe ka maemo a moamoheli a le mong le a nang le batho ba babeli. Ka kakaretso, stack e tšoana bakeng sa moamoheli ea habeli, re eketsa SMCU.

• NXP I2C Driver ke kernel module e fanang ka phihlello ea lisebelisoa tsa hardware tsa PN7220.
• Mojule oa HAL ke ts'ebetsong ea karolo e ikhethileng ea HW ea taolo ea NXP NFC.
• LibNfc-nci ke laeborari ea lehae e fanang ka ts'ebetso ea NFC.
• NFC JNI ke khoutu ea sekhomaretsi lipakeng tsa lihlopha tsa Java le Native.
• Moralo oa NFC le EMVCo ke mojule oa moralo oa ts'ebeliso o fanang ka phihlello ea tšebetso ea NFC le EMVCo.

Mokhanni oa Kernel

The NFC Android stack e sebelisa nxpnfc kernel mokhanni ho buisana le PN7220. E fumaneha mona.

2.1 Lintlha tsa mokhanni
Mokhanni oa kernel oa nxpnfc o fana ka puisano le PN7220 holim'a sebopeho sa 'mele sa I2C.
Ha e kentsoe ka har'a kernel, mokhanni enoa o pepesa sebopeho ho PN7220 ka node ea sesebelisoa e bitsoang /dev/nxpnfc.

2.2 Ho fumana khoutu ea mohloli
Koala polokelo ea mokhanni oa PN7220 bukeng ea kernel, u nkela ts'ebetsong e teng:
$ rm -rf bakhanni / nfc
$git clone"https://github.com/NXPNFCLinux/nxpnfc.git“-b PN7220-Bakhanni ba bakhanni/

Sena se qetella ka foldara driver/nfc e nang le tse latelang files:

• README.md: lintlha tsa polokelo
• Etsa file: mokhanni heading make file
• Kcon fig: tlhophiso ea mokhanni file
• License: lipehelo tsa tumello ea ho khanna
• foldara e nyane ea nfc e nang le:
  - commoc. c: ts'ebetsong ea mokhanni ea tloaelehileng
  – e tlwaelehileng. h: generic driver interface definition
  - i2c_drv.c: ts'ebetsong ea mokhanni oa i2c ka ho khetheha
  – i2c_drv.h: i2c specific driver interface definition
  - Etsafile: etsafile e kenyellelitsoeng ho makefile ea moqhobi
  – Kbuild => haha file
  - Kconfig => tlhophiso ea mokhanni file

2.3 Ho aha mokhanni
Ho kenyelletsa mokhanni ka har'a kernel le ho e etsa hore e be mojaro nakong ea bootla ea sesebelisoa e etsoa ka lebaka la sefate sa mochine.
Ka mor'a ho ntlafatsa tlhaloso ea sefate sa sesebelisoa, sefate sa sesebelisoa se amanang le sethala se tlameha ho tsosolosoa. NXP e fana ka maikutlo a ho sebelisa mofuta oa kernel 5.10, kaha phetolelong ena ho entsoe netefatso e felletseng.

1. Khoasolla kernel
2. Fumana khoutu ea mohloli oa mokhanni.
3. Fetola tlhaloso ea sefate sa sesebelisoa (ka ho khetheha ho sesebelisoa seo re se sebelisang).
4. Haha mokhanni.
   a. Ka mokhoa oa menuconfig, kenyelletsa mokhanni ea shebiloeng mohahong.

Ka mor'a ho tsosolosa kernel e feletseng, mokhanni o tla kenngoa setšoantšong sa kernel. Re tlameha ho etsa bonnete ba hore litšoantšo tsohle tse ncha tsa kernel li kopitsoa moahong oa AOSP.

AOSP ho ikamahanya le maemo

NXP e fana ka li-patches ka holim'a khoutu ea AOSP. Seo se bolela hore mosebelisi a ka qala ho fumana khoutu ea AOSP mme a sebelisa li-patches ho tsoa ho NXP. Karolo ena e hlalosa mokhoa oa ho phethahatsa sena. AOSP ea hona joale tag eo re e sebelisang ke [1].

3.1 Mohaho oa AOSP

1. Re tlameha ho fumana khoutu ea mohloli oa AOSP. Sena re ka se etsa ka:
   $ repo init -u https://android.googlesource.com/platform/manifest-b android-13.0.0_r3
   $ repo sync
   Tlhokomeliso: Sesebelisoa sa repo se tlameha ho kenngoa tsamaisong. Latela litaelo [2].
2. Ha re e-na le khoutu ea mohloli, re ka kenya directory ebe re e haha:
   $cd Android_AROOT
   $source build/envsetup.sh
   $lunch select_target #target ke DH eo re batlang ho e sebelisa bakeng sa example: db845c-userdebug $make -j
3. Ha AOSP e hahuoa ka katleho, re tlameha ho fumana li-patches tsa NXP. Sena re ka se etsa ka:
   $git clone"https://github.com/NXPNFCLinux/PN7220_Android13.git” morekisi/nxp/
4. Mothating ona, bohle re hloka ho kenya li-patches bakeng sa tšehetso ea PN7220. Re ka sebelisa li-patches ka ho sebelisa mongolo oa install_NFC.sh.
   $chmod +x /vendor/nxp/nfc/install_NFC.sh #ka linako tse ling re hloka ho kenyelletsa litokelo tse ka phethoang ho script
   $./vendor/nxp/nfc/install_NFC.sh
   Hlokomela: Sheba sephetho ka mor'a ho sebelisa install_NFC.sh. Haeba ho hlokahala, re tlameha ho etsa liphetoho tse itseng ka letsoho.
5. Hape re ka eketsa li-binary tsa FW:
   $git clone xxxxxxx
   $cp -r nfc-NXPNFCC_FW/InfraFW/pn7220/64-bit/libpn72xx_fw.so AROOT/vendor/nxp/pn7220/firmware/lib64/libpn72xx_fw.so

6. E eketsa NFC ho aha
   Ka sesebelisoa.mk etsafile (mohlalaample, device/brand/platform/device.mk), kenyeletsa maketse e itsengfiles:
   $(call inherit-product, vendor/nxp/nfc/device-nfc.mk)
   Ho BoardConfig.mk etsafile (mohlalaample, device/brand/platform/BoardConfig.mk), kenyeletsa e itseng makefile:
   - kenyeletsa morekisi/nxp/nfc/BoardConfigNfc.mk
7. E eketsa ts'ebeliso ea DTA
   $git clone https://github.com/NXPNCPProject/NXPAndroidDTA.git $git checkout NFC_DTA_v13.02_OpnSrc $patch -p1 AROOT_system_nfc-dta.patch
   $ cp -r nfc-dta /system/nfc-dta
   $ /system/nfc-dta/$ mm -j
8. Joale re ka haha ​​​​AOSP hape ka liphetoho tsohle tseo re li entseng:
   $ cd moralo / motheo
   $mm
   $cd ../..
   $ cd morekisi/nxp/frameworks

   $etsa -j
   Hona joale, re khona ho khantša moamoheli oa sesebelisoa sa rona ka setšoantšo sa Android se kenyelletsang likarolo tsa NFC.
