(2) Wepụta SWD interface, na-akwado sọftụwia debugging PC, gụnyere keil, IAR, openocd, nkwado nbudata SwD, nbibi otu nzọụkwụ.
(3) JTAG interface, na openocd nwere ike ịkwado debugging nke ihe fọrọ nke nta ka ọ bụrụ ihe niile SoC ibe n'ụwa nile, dị ka ARM Cortex-A usoro, DSP, FPGA, MIPS, wdg, n'ihi na SWD protocol bụ naanị a nzuzo protocol kọwara site ARM, na JTAG bụ ọkọlọtọ IEEE 1149 mba ụwa. Ihe mgbawa ebumnuche emulator na-emekarị bụ usoro ARM Cortex-M, nke na-adịghị ewebata interface JTAG, yana ngwaahịa a na-ewebata interface JTAG, nke dabara gị mma ịzụlite na debug ọrụ n'okpuru nyiwe ndị ọzọ.

Ajụjụ & A
1. Ọkụ na-ere ọkụ, na-egosi RDDI-DAP ERROR, otu esi edozi?
A: N'ihi na simulator ọkụ na-agba ọsọ ngwa ngwa, mgbaàmà n'etiti dupont akara ga-emepụta crosstalk, biko gbalịa ịgbanwe mkpụmkpụ Dupont ahịrị, ma ọ bụ na njikọ chiri anya Dupont akara, ị nwekwara ike na-agbalị ibelata ọkụ ọkụ, n'ozuzu nwere ike dozie. na-emekarị.
2. Kedu ihe a ga-eme ma ọ bụrụ na enweghị ike ịchọta ihe mgbaru ọsọ, na-egosi ọdịda nkwurịta okwu?
A: Biko buru ụzọ lelee ma eriri ngwaike ọ bụ eziokwu (GND,CLK,10,3V3), wee lelee ma ọkọnọ ike nke bọọdụ ebumnuche ọ bụ ihe nkịtị. Ọ bụrụ na bọọdụ ebumnuche bụ simulator na-akwado ya, ebe ọ bụ na ihe kacha arụ ọrụ ugbu a nke USB bụ naanị 500mA, biko lelee ma ike nke bọọdụ ebumnuche ezughi oke.
3. Kedu mgbawa debugging ọkụ na-akwado CMSIS DAP/DAPLink?
A: Ihe omume a na-ahụkarị bụ ịhazi na debug MCU. N'ụzọ doro anya, kernel nke usoro Cortex-M nwere ike iji DAP maka ọkụ na debugging, ụdị ibe dị ka STM32 zuru ezu usoro nke ibe, GD32 zuru ezu usoro, nRF51/52 usoro na na.
4. Enwere m ike iji DAP emulator maka debugging n'okpuru Linux?
A: N'okpuru Linux, ị nwere ike iji openocd na DAP emulator maka debugging. openocd bụ ihe nbibi isi mmalite kachasị ewu ewu na ike n'ụwa. Ị nwekwara ike iji openocd n'okpuru windo, site na ịde ederede nhazi kwesịrị ekwesị nwere ike nweta nkwụsị nke mgbawa, ọkụ na ọrụ ndị ọzọ.
