![Ljut ko... :azdaja:](./images/smilies/azdaja.gif)
No uglavnom, pokušavam isprogramirat FPGA preko bin file-a bez programatora i taj dio radi, jednostavno sam s logičkim analizatorom pratio komunikaciju između FPGA i usb blastera, napisao arduino program da čita bin file s sd kartice i ok uspio sam isprogramirat FPGA.
E sad pošto sve to trebam prebacit na STM32 a i bilo bi ok zapravo razumjet što se događa u komunikaciji zanima me dal neko ima kakvu literaturu o JTAG komunikaciji?? ovo sve što sam na google-u našao mi ne služi praktički nićemu.... sve je to površno.
Zapravo me zanima recimo nalazim se u data registru i hoću iči u instruction registar, dali smijem iči u "run test/idle state" ili moram odma u instruction registar ili će ono što je uprisano u DR biti izbrisano?
Odnosno dali je isto:
exit DR -> update DR -> select DR -> select IR -> capture IR -> shift IR
kao i:
exit DR -> update DR -> ->run test/idle -> select DR -> select IR -> capture IR -> shift IR
Isto tako nije mi baš najjasnije zašto nekad program ide kroz exit DR i update DR s data line = 1 a nekad je 0?
Zašto nekada program više puta u isti registar upisuje istu vrijednost??? Recimo dva tri puta prolazi kroz instruction registar i upisuje iste vrijednosti??
no kao što vidite nemam pojma ništa o JTAG-u pa ako neko ima nekakvu literaturu bilo bi super.
Ako nekoga interesira arduino program .. eto ga
