SmartFusion2 SoC FPGA - Code Shadowing kubva kuSPI Flash kuenda kuLPDDR Memory

Nhanganyaya
Iyi demo dhizaini inoratidza SmartFusion2 SoC FPGA mudziyo kugona kwekodhi shadowing kubva kune serial peripheral interface (SPI) flash memory mudziyo kune yakaderera simba kaviri data data (LPDDR) synchronous dynamic random access memory (SDRAM) uye kuita kodhi kubva kuLPDDR SDRAM. Mufananidzo 1 unoratidza iyo yepamusoro-level block dhizaini yekodhi shadowing kubva kuSPI flash mudziyo kuenda kuLPDDR memory.

Mufananidzo 1 Yepamusoro-Level Block Diagram yeDemo

Code shadowing inzira yekubhowa iyo inoshandiswa kumhanyisa mufananidzo kubva kunze, nekukurumidza, uye nekusagadzikana ndangariro (DRAM). Ndiyo maitiro ekukopa kodhi kubva kusinga-volatile ndangariro kuenda kune volatile memory yekuitwa. Code shadowing inodiwa, kana ndangariro isiri-inoshanduka yakabatana ne processor isingatsigire kuwana zvisina kujairika kune kodhi yekuitisa-mu-nzvimbo, kana paine kusakwana kusiri-kuvhuvhuta kungoerekana kwaitika ndangariro. Mukuita-akakosha maapplication, kumhanya kwekuita kunogona kuvandudzwa nekodhi shadowing, uko kodhi inokopwa kune yakakwirira throughput RAM kuti iite nekukurumidza. Single data rate (SDR)/DDR SDRAM ndangariro dzinoshandiswa mumashandisirwo ane hombe application inogoneka mufananidzo uye inoda kushanda kwepamusoro. Kazhinji, mifananidzo mikuru inogoneka inochengeterwa mundangariro dzisiri-dzinoshanduka, senge NAND flash kana SPI flash, uye inokopwa kune inoshanduka ndangariro, senge SDR/DDR SDRAM ndangariro, pasimba rekuurayiwa. SmartFusion2 zvishandiso zvinosanganisa chizvarwa chechina flash-based FPGA jira, iyo ARM® Cortex®-M3 processor, uye yakakwirira mashandiro ekutaurirana maficha pane imwechete chip. Iwo akakwira ekumhanya ndangariro anodzora muSmartFusion2 zvishandiso anoshandiswa kubatanidza neyekunze DDR2/DDR3/LPDDR ndangariro. Iyo LPDDR ndangariro inogona kushanda nekumhanya kwakanyanya kwe166 MHz. Iyo Cortex-M3 processor inogona kumhanyisa mirairo kubva kunze kweDDR memory kuburikidza neiyo microcontroller subsystem (MSS) DDR (MDDR). Iyo FPGA Cache Controller uye MSS DDR bhiriji inobata kuyerera kwedata kuti iite zvirinani.

Demo Dhizaini Tsananguro

Iyi demo dhizaini inoshandisa kodhi shadowing maitiro kubhuya iyo application mufananidzo kubva kuDDR memory. Iyi dhizaini inopawo host interface pamusoro peSmartFusion2 SoC FPGA yakawanda-mode universal asynchronous/synchronous receiver/transmitter (MMUART) kurodha iyo yakanangwa application inogoneka mufananidzo muSPI flash yakabatana neMSS SPI0 interface.
Iyo code shadowing inoitwa nenzira mbiri dzinotevera:

• Zvakawanda-stage boot process nzira uchishandisa iyo Cortex-M3 processor
• Hardware boot injini nzira uchishandisa iyo FPGA jira.

Zvakawanda-StageBoot process Method

1. Gadzira mufananidzo wekunyorera weDDR memory uchishandisa iyo Libero SoC software.
2. Rodha SPI Flash loader muSPI flash uchishandisa Libero SoC software.
3. Mhanya iyo Code Shadowing Demo GUI kuronga iyo FPGA uye kurodha iyo application mufananidzo kubva kuSPI flash kuenda kuLPDDR memory.

Mufananidzo wekushandisa unomhanyiswa kubva kunze kweDDR ndangariro mune maviri anotevera boot stages:

• Iyo Cortex-M3 processor inobhutsu yakapfava bootloader kubva yakamisikidzwa isiri-inotenderera ndangariro (eNVM), iyo inoita iyo kodhi mufananidzo wekufambisa kubva kuSPI flash mudziyo kuenda kuDDR memory.
• Iyo Cortex-M3 processor inobhutsu mufananidzo wekushandisa kubva kuDDR memory.

Iyi dhizaini inoshandisa bhootloader chirongwa kurodha iyo yakanangwa application inogoneka mufananidzo kubva kuSPI flash mudziyo kuenda kuDDR memory yekuitwa. Chirongwa chebootloader chinomhanya kubva kuNVM chinosvetukira kune chinongedzo application chakachengetwa muDDR ndangariro mushure mekunge iyo yakanangwa application mufananidzo wakopwa kuDDR memory.

Mufananidzo 3 Code Shadowing Multi-StageBoot process Demo Block Diagram

Iyo MDDR yakagadzirirwa LPDDR kushanda pa166 MHz. "Appendix: LPDDR Configurations" papeji 22 inoratidza LPDDR zvigadziriso. Iyo DDR inogadziriswa isati yaita iyo huru yekushandisa kodhi.

Bootloader

Iyo bootloader inoita mabasa anotevera:

1. Kukopa iyo yakanangwa application mufananidzo kubva kuSPI flash memory kuenda kuDDR memory.
2. Kudzorera DDR ndangariro yekutanga kero kubva 0xA0000000 kusvika 0x00000000 nekugadzirisa DDR_CR system register.
3. Kutanga iyo Cortex-M3 processor stack pointer sekuenderana nechinangwa chekushandisa. Nzvimbo yekutanga yechinangwa chekushandisa vector tafura ine stack pointer kukosha. Iyo vector tafura yechinangwa chekushandisa inowanikwa kutanga kubva kukero 0x00000000.
4. Kurodha kaunda yepurogiramu (PC) kuseta zvakare mubati wechinangwa chekushandisa chekumhanyisa iyo yakanangwa application mufananidzo kubva kuDDR memory. Reset mubati wechinangwa chekushandisa chinowanikwa mune vector tafura pakero 0x00000004.

Mufananidzo 4 Dhizaini Inoyerera yeMulti-StageBoot process Method

Hardware Boot Injini Nzira

1. Gadzira bhinari inogoneka file uchishandisa iyo Libero SoC software.
2. Rodha iyo binary file muSPI flash uchishandisa iyo Libero SoC software.
3. Mhanya iyo Hardware Boot Engine Dhizaini kuronga iyo FPGA uye kurodha iyo application mufananidzo kubva kuSPI flash kuenda kuLPDDR memory.

Munzira iyi, iyo Cortex-M3 inobhutsu yakanangana nechiratidzo chekushandisa kubva kunze kweDDR ndangariro. Iyo hardware boot injini inokopa mufananidzo wekushandisa kubva kuSPI flash mudziyo kuenda kuDDR memory, isati yaburitsa Cortex-M3 processor reset. Mushure mekusunungura iyo reset, iyo Cortex-M3 processor bhutsu yakananga kubva kuDDR memory. Iyi nzira inoda nguva shoma yeboot-up pane yakawanda-stage boot process sezvo ichidzivirira akawanda boot stages uye inokopa mufananidzo wekushandisa kuDDR memory munguva shoma. Iyi dhizaini yedhizaini inoshandisa boot injini logic muFPGA jira kukopa iyo yakanangwa application inogoneka mufananidzo kubva kuSPI flash kuenda kuDDR ndangariro kuti iitwe. Iyi dhizaini zvakare inoshandisa SPI flash loader, iyo inogona kuitwa neCortex-M3 processor kurodha yakanangwa application inogoneka mufananidzo muSPI flash mudziyo uchishandisa yakapihwa host interface pamusoro peSmartFusion2 SoC FPGA MMUART_1. Iyo DIP switch1 paSmartFusion2 Chengetedzo Yekuongorora Kit inogona kushandiswa kusarudza kana kuronga SPI flash mudziyo kana kuita kodhi kubva kuDDR memory. Kana iyo inogoneka chinangwa application iripo muSPI flash mudziyo, iyo kodhi mumvuri kubva kuSPI flash mudziyo kuenda kuDDR memory inotangwa pane mudziyo simba-kumusoro. Injini yebhutsu inotanga MDDR, inokopa Mufananidzo kubva kuSPI flash mudziyo kuenda kuDDR ndangariro, uye inodzosera iyo DDR ndangariro nzvimbo kusvika 0x00000000 nekuchengetedza Cortex-M3 processor mukugadzirisa. Mushure mebhoti injini yaburitsa iyo Cortex-M3 reset, iyo Cortex-M3 inoita chinangwa chekushandisa kubva kuDDR memory. Mufananidzo 5 unoratidza yakadzama dhizaini yedhizaini yedemo. Iyo FIC_0 inogadziriswa muSlave mode kuti iwane iyo MSS SPI_0 kubva kuFPGA jira AHB master. Iyo MDDR AXI interface (DDR_FIC) inogoneswa kuwana iyo DDR ndangariro kubva kuFPGA jira AXI master.
