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 mmemme 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.
