Drasko , Thank you for your reply. > Yes and no. > mwh stands for "memory write half (word)", i.e.16 bits, i.e. 2 bytes (not 4 > as you mentioned). do you mean mwh should display 4 characters because each character are 4 bits? Is it so?

I posted bugs I received when trying my MIPS CPU to enter debug mode. But no response from the developer (Who wrote the programs for MIPS CPU support of OpenOCD?) so I started using my own program, inspired by HairyDairyMaid's program which uses PRACC | PROBEN | SETDEV | JTAGBRK masks to bring CPU into Debug mode and also PRRST | PERRST before the above to halt CPU #define TOF (1 << 1 ) #define TIF (1 << 2 ) #define BRKST (1 << 3 ) #define DLOCK (1 << 5 ) #define DRWN (1 << 9 ) #define DERR (1 << 10) #define DSTRT (1 << 11) #define JTAGBRK (1 << 12) #define SETDEV (1 << 14) #define PROBTRAP (1 << 14) #define PROBEN (1 << 15) #define PRRST (1 << 16) #define DMAACC (1 << 17) #define PRACC (1 << 18) #define PRNW (1 << 19) #define PERRST (1 << 20) #define HALT (1 << 21) #define DOZE (1 << 22) #define SYNC (1 << 23) #define DNM (1 << 28) #define ROCC (1 << 31) And that brings CPU into Debug mode nicely.
