Good news - I have managed to perform bidirectional communications with the STM32(Primer2) using ft2232h device (kt-link) + libswd incorporated into urjtag using its drivers!
I had some hard time recently caused by incompetent people at ARM writing documentation - even most "up to date" documentation is sooo buggy: -APnDP should be 0 not 1 on idcode read -there is an additional IDLE state required after synchronous reset/dap_select sequence, but there is no word about it on the documents (aarrgggGHH^WT^#@&ET^!&T!^&!!!!! this stole some time from me) -it is written so that most of the diagrams are partialy msb-first and some lsb-first on the same timeline and this is confusing -adi documentation dissaperared from their repository -because no logic analyzer i was not able to compare my signalling with one generated by rlink but the second generates lots of short and fast bursts of bits I did not even imagine ARM documentation to be that bad. Anyway, the work should accelerate now as most of the libswd is verified and functional :-) Best regards, Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
