SWD and other transports will use bitbang() and transfer() new interface methods to work on the bus. queue_flush() / execute_queue() is jtag only function and should not be used for transports other than jtag, as it is too jtag-only as it works on commands queued on CMD_CTX, but these are jtag only. the idea is to become transport independent, so the context and queue will be now part of given transport. libswd for instance has swd_ctx holding all settings and queue, each libswd function works on this context, so there may be many different contexts in use with no collisions. this swd_ctx will be hold by void pointer in transport structure (void so any other context can be used as well). > i need is some way to type "my_function_in_ft2232.c some_arg" in the > telnet interface so that the function my_function in ft2232.c gets > called... > i managed to make the chip do what i needed without using swd. > maybe i can get around with some patch on ft2232.c and jtag interface... > > how are you testing stuff without the "jtag" command in the cfg files? target operations are not yet ready. jtag functions are jtag only. agree there is a mess because i am using some functions or structures having "jtag" in their name only because some time ago noone considered other transports than jtag, so instead oocd_interface there is jtag_interface etc. this must be fixed after transport is functional, i wanted to rename this stuff before but it took too much time, so i decided to first make transport working and later reorganize openocd interals as time is limited... Best regards! :-) Tomek btw. maybe automatically executing autoreconf for libswd submodule will fix the problem you mentioned.. i have created configure script to avoid this, but there seems to be someissues with that.. will have to take closer look :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
