Microsemi-SmartFusion2-SoC-FPGA-Code-Shadowing-ukusuka-SPI-Flash-to-DDR-Memory-01

Ikhowudi yokufihla ikhowudi yindlela yokuqalisa esetyenziswa ukuqhuba umfanekiso osuka ngaphandle, okhawulezayo, kunye neenkumbulo eziguqukayo (DRAM). Yinkqubo yokukopa ikhowudi kwimemori engaguquguqukiyo ukuya kwimemori eguquguqukayo yokuphunyezwa.

Ukufihlwa kwekhowudi kuyafuneka xa inkumbulo engaguquguqukiyo edityaniswe nomqhubekekisi ayikuxhasi ufikelelo olungacwangciswanga kwikhowudi yophumezo-kwindawo, okanye kukho ukungonelanga kwememori yofikelelo olungaguquguqukiyo olunganelanga. Kwizicelo ezibalulekileyo zokusebenza, isantya sokwenza sinokuphuculwa ngokuthunjwa kwekhowudi, apho ikhowudi ikopishwa kwi-RAM ephezulu yokusetyenziswa ngokukhawuleza.

Izinga ledatha enye (SDR)/DDR SDRAM iinkumbulo zisetyenziswa kwizicelo ezinomfanekiso ophunyeziweyo wesicelo kwaye zifuna ukusebenza okuphezulu. Ngokuqhelekileyo, imifanekiso emikhulu ephunyeziweyo igcinwa kwimemori engaguquguqukiyo, efana ne-NAND flash okanye i-SPI flash, kwaye ikhutshelwe kwimemori eguquguqukayo, njengememori ye-SDR / DDR SDRAM, kumandla okuphumeza.

Izixhobo ze-SmartFusion2 SoC FPGA zidibanisa ilaphu le-FPGA yesizukulwana sesine, iprosesa ye-ARM® Cortex®-M3, kunye nonxibelelwano oluphezulu lonxibelelwano kwi-chip enye. Abalawuli bememori yesantya esiphezulu kwi-SmartFusion2 SoC FPGA izixhobo zisetyenziselwa ukusebenzelana neenkumbulo zangaphandle zeDDR2/DDR3/LPDDR. Iinkumbulo zeDDR2/DDR3 zinokuqhutywa ngesantya esiphezulu se-333 MHz. Iprosesa yeCortex-M3 inokuqhuba ngokuthe ngqo imiyalelo evela kwimemori yangaphandle ye-DDR ngokusebenzisa i-microcontroller subsystem (MSS) DDR (MDDR). Umlawuli we-cache ye-FPGA kunye nebhuloho ye-MSS DDR iphatha ukuhamba kwedatha ukwenzela ukusebenza okungcono.

I-Hardware Boot yeNjini yeNdlela
Kule ndlela, i-Cortex-M3 iqala ngokuthe ngqo umfanekiso wesicelo esijoliswe kuyo kwiinkumbulo zangaphandle ze-DDR. Injini ye-hardware yokuqalisa ikopi ikopi yomfanekiso wesicelo kwisixhobo sombane se-SPI ukuya kwimemori ye-DDR, ngaphambi kokukhulula i-Cortex-M3 yokusetha kwakhona iprosesa. Emva kokukhulula ukusetha kwakhona, iprosesa ye-Cortex-M3 iqala ngokuthe ngqo kwimemori ye-DDR. Le ndlela ifuna ixesha elincinane lokuqalisa kune-multi-staginkqubo yesiqalo njengoko inqanda isiqalo ezininzitages kwaye ikhuphela umfanekiso wesicelo kwimemori ye-DDR ngexesha elincinci.

Olu luyilo lwedemo lusebenzisa ingqiqo ye-injini ye-boot kwilaphu leFPGA ukukopa umfanekiso ophunyeziweyo wesicelo ukusuka kwi-SPI flash ukuya kwimemori ye-DDR ukuze iphunyezwe. Olu luyilo lukwasebenzisa isilayishi se-SPI esinokukhanya, esinokwenziwa yiCortex-M3 iprosesa ukulayisha umfanekiso ophunyezwayo wesicelo kwisixhobo sombane seSPI usebenzisa ujongano olunikiweyo lomamkeli ngaphezulu kweSmartFusion2 SoC FPGA MMUART_0. I-DIP switch1 kwi-SmartFusion2 Advanced Development Kit ingasetyenziselwa ukukhetha ukuba inkqubo ye-SPI flash device okanye ukwenza ikhowudi kwimemori ye-DDR.

Ukuba usetyenziso lwethagethi oluphunyeziweyo luyafumaneka kwisixhobo sombane seSPI, ikhowudi yokuthungatha ukusuka kwisixhobo sombane seSPI ukuya kwimemori yeDDR iqalwa kumandla-phezulu wesixhobo. Injini yokuqalisa iqalisa i-MDDR, ikhuphela uMfanekiso kwisixhobo sombane se-SPI ukuya kwimemori ye-DDR, kwaye iphinde ibuyisele isithuba sememori ye-DDR ukuya kwi-0x00000000 ngokugcina i-Cortex-M3 iprosesa iseti ngokutsha. Emva kokuba injini yokuqalisa ikhuphe ukusetwa kwakhona kweCortex-M3, iCortex-M3 iphumeza usetyenziso olujoliswe kuyo kwimemori ye-DDR.

I-FIC_0 iqwalaselwe kwimowudi yeKhoboka ukufikelela kwi-MSS SPI_0 ukusuka kwi-FPGA ilaphu le-AHB inkosi. I-interface ye-MDDR AXI (DDR_FIC) yenziwe ukuba ifikelele kwimemori ye-DDR ukusuka kwi-FPGA yelaphu ye-AXI master.

Le yeyona nxalenye iphambili yedemo yokufihla ikhowudi ekhuphela umfanekiso wesicelo kwisixhobo sombane seSPI kwimemori yeDDR. Injini yokuqalisa yenza le misebenzi ilandelayo:

  1. Ukuqalisa i-MDDR yokufikelela kwi-DDR3 kwi-320 MHz ngokugcina iprosesa ye-Cortex-M3 iseti ngokutsha.
  2. Ukukhuphela umfanekiso wesicelo ekujoliswe kuso kwisixhobo sememori ye-SPI kwimemori ye-DDR usebenzisa i-AXI master kwilaphu leFPGA ngokusebenzisa ujongano lwe-MDDR AXI.
  3. Ukubuyisela imemori ye-DDR idilesi yokuqala ukusuka kwi-0xA0000000 ukuya kwi-0x00000000 ngokubhalela kwirejista ye-DDR_CR yenkqubo.
  4. Ikhulula ukusetwa kwakhona kwiCortex-M3 iprosesa ukuqala kwimemori yeDDR.

Kuyilwa iSicelo sokuJonga esiJongene kwimemori ye-DDR
Umfanekiso onokuthi uphunyezwe kwimemori ye-DDR uyafuneka ukuqhuba idemo. Sebenzisa i-"production-execute-in-place-externalDDR.ld" inkcazo yekhonkco file oko kubandakanyiwe kuyilo files ukwakha umfanekiso wesicelo. Inkcazo yomnxibelelanisi file ichaza idilesi yokuqalisa imemori ye-DDR njengo-0x00000000 ukususela ekubeni i-bootloader/injini yokuqalisa yenza imemori ye-DDR yenza imemori kwakhona ukusuka ku-0xA0000000 ukuya kwi-0x00000000. Iskripthi se-linker senza umfanekiso wesicelo kunye nemiyalelo, idatha, kunye namacandelo e-BSS kwimemori idilesi yayo yokuqala yi-0x00000000. I-diode elula ekhupha ukukhanya (i-LED) ukuqhwanyaza, isibali-xesha kunye nokutshintsha okusekelwe kukuphazamiseka komfanekiso wesicelo sokuvelisa file inikezelwe kule demo.

SPI Flash Loader
Umlayishi we-SPI uphunyeziwe ukulayisha imemori yeflash ye-SPI ekwibhodi ngomfanekiso wesicelo esiphunyeziweyo osuka kumamkeli wePC ngojongano lweMMUART_0. I-Cortex-M3 iprosesa yenza isithinteli sedatha esiza ngaphaya kojongano lweMMUART_0 kwaye iqalise iperipheral DMA (PDMA) ukubhala idatha ekhuselweyo kwi-SPI flash nge-MSS_SPI0.

Ukuqhuba iDemo
Idemo ibonisa indlela yokulayisha umfanekiso wesicelo kwi-SPI flash kwaye uphumeze loo mfanekiso wesicelo kwiinkumbulo zangaphandle ze-DDR. Ibonelela nge exampumfanekiso wesicelo “sample_image_DDR3.bin”. Lo mfanekiso ubonisa imiyalezo eyamkelekileyo kunye nokuphazamiseka komyalezo wesibali kwi-serial console kwaye uqhwanyaza i-LED1 ukuya kwi-LED8 kwi-SmartFusion2 Advanced Development Kit.
