DAPLINK hloov JLINK OBSTLINK STM32 burner down-loader emulator ARM

Cov yam ntxwv ntawm cov khoom
(1) Hardware schematic PCB yog qhov qhib kiag li, software qhib qhov chaw, tsis muaj kev pheej hmoo.
Tam sim no, jlink / stlink ntawm kev ua lag luam yog pirated, thiab muaj qee qhov teeb meem raug cai hauv kev siv.Thaum qee qhov jlink siv nrog IDE xws li MDK, nws yuav ua rau piracy thiab tsis tuaj yeem siv ib txwm, thiab qee qhov jlink versions muaj teeb meem poob firmware tom qab siv rau lub sijhawm.Thaum lub firmware ploj lawm, koj yuav tsum manually restore lub software.
(2) Ua tawm SWD interface, txhawb nqa PC debugging software, suav nrog keil, IAR, openocd, txhawb nqa SwD download, ib kauj ruam debugging.
(3) JTAG interface, nrog openocd tuaj yeem pab txhawb kev debugging ntawm yuav luag tag nrho SoC chips thoob ntiaj teb, xws li ARM Cortex-A series, DSP, FPGA, MIPS, thiab lwm yam, vim tias SWD raws tu qauv tsuas yog ib txoj cai ntiag tug txhais los ntawm ARM, thiab JTAG yog tus qauv thoob ntiaj teb IEEE 1149.Lub hom phiaj emulator ib txwm nti yog feem ntau ARM Cortex-M series, uas tsis qhia JTAG interface, thiab cov khoom no qhia JTAG interface, uas yog tsim rau koj los tsim thiab debug ua hauj lwm nyob rau hauv lwm lub platforms.
(4) Txhawb qhov chaw nres nkoj virtual (uas yog, nws tuaj yeem siv los ua tus emulator lossis ua cov cuab yeej chaw nres nkoj, hloov ch340, cp2102, p12303)
(5) DAPLink txhawb USB flash drive firmware upgrade, tsuas yog hauv av nRST, ntsaws rau hauv DAPLink, PC.Yuav muaj USB flash drive, tsuas yog rub lub firmware tshiab (hex lossis bin file) rau hauv USB flash drive kom ua tiav cov firmware upgrade.Vim tias DAPLink siv lub bootloader nrog U disk muaj nuj nqi, nws tuaj yeem ua tiav qhov hloov kho firmware tau yooj yim.Yog tias koj muaj STM32-raws li cov khoom lag luam hauv kev tsim khoom loj, thiab cov khoom yuav tsum tau hloov kho tom qab, cov khau raj loader code hauv DAPLink yog qhov tsim nyog rau koj siv, tus neeg siv khoom tsis tas yuav teeb tsa IDE complex lossis hlawv cov cuab yeej ua kom tiav. hloov kho dua tshiab, tsuas yog rub mus rau U disk tuaj yeem ua tiav koj cov khoom hloov kho kom yooj yim.

Q&A
1. Hlawv tsis ua hauj lwm, qhia RDDI-DAP ERROR, yuav daws li cas?
A: Vim hais tias lub simulator kub ceev ceev, lub teeb liab ntawm dupont kab yuav tsim crosstalk, thov sim hloov lub luv dua Dupont kab, los yog cov kab txuas nrog Dupont, koj tuaj yeem sim txo qhov kub ceev, feem ntau tuaj yeem daws tau. ib txwm.
2. Yuav ua li cas yog tias lub hom phiaj tsis tuaj yeem kuaj pom, qhia tias kev sib txuas lus tsis ua haujlwm?
A: Thov ua ntej xyuas seb lub hardware cable puas yog (GND, CLK, 10,3V3), thiab tom qab ntawd xyuas seb lub hwj chim ntawm lub hom phiaj yog qhov qub.Yog hais tias lub hom phiaj lub rooj tsavxwm yog powered los ntawm lub simulator, txij li thaum lub siab tshaj plaws tso zis tam sim no ntawm lub USB tsuas yog 500mA, thov xyuas seb lub hwj chim mov ntawm lub hom phiaj board yog tsis txaus.
3. Qhov twg chip debugging hlawv yog txhawb los ntawm CMSIS DAP/DAPLink?
A: Cov xwm txheej siv ib txwm yog los ua haujlwm thiab kho qhov MCU.Raws li kev xav, cov ntsiav ntawm Cortex-M series tuaj yeem siv DAP rau kev hlawv thiab kev debugging, cov chips raug xws li STM32 tag nrho cov chips, GD32 full series, nRF51/52 series thiab lwm yam.
4. Kuv puas tuaj yeem siv DAP emulator rau kev debugging hauv Linux?
A: Hauv Linux, koj tuaj yeem siv openocd thiab DAP emulator rau kev debugging.openocd yog qhov nrov tshaj plaws thiab muaj zog qhib qhov debugger hauv ntiaj teb.Koj tuaj yeem siv openocd nyob rau hauv windows, los ntawm kev sau cov ntawv tsim nyog tsim nyog tuaj yeem ua tiav qhov kev debugging ntawm nti, hlawv thiab lwm yam haujlwm.
