Hello I am very new to JTAG and i am trying to do the setup for jtag in beaglebone black(BBB) rev c board using buspirate(BP) and openocd. I have installed the P2 header in BBB manually. I have connected the BBB and BP as follows
JTAG BP BBB TMS CS P2(1) P2 header pin 1 TDI MOSI P2(3) VTREF VPU P2(5) TDO MISO P2(7) TCK CLK P2(11) TRST AUX P2(2) GRND GND P2(10) I am using my user configuration file(BP_userconfig.cfg) for openocd which has following content. source [find interface/buspirate.cfg] buspirate_vreg 0 buspirate_mode open-drain buspirate_pullup 1 reset_config srst_only buspirate_port /dev/ttyUSB0 source [find board/ti_beaglebone_black.cfg] Now while running the command *sudo openocd -f BP_userconfig.cfg* I am getting following error. *lenova@lenova-ThinkPad-T410:~/jiten/JTAG$ sudo openocd -f BP_userconfig.cfg Open On-Chip Debugger 0.10.0+dev-00167-g29cfe9c (2017-07-20-14:08)Licensed under GNU GPL v2For bug reports, read http://openocd.org/doc/doxygen/bugs.htmlWarn : Adapter driver 'buspirate' did not declare which transports it allows; assuming legacy JTAG-onlyInfo : only one transport option; autoselect 'jtag'srst_only separate srst_gates_jtag srst_open_drain connect_deassert_srsttrst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain connect_deassert_srstadapter speed: 1000 kHztrst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain connect_deassert_srstInfo : Buspirate Interface ready!Info : This adapter doesn't support configurable speedInfo : JTAG tap: am335x.jrc tap/device found: 0x2b94402f (mfg: 0x017 (Texas Instruments), part: 0xb944, ver: 0x2)Info : JTAG tap: am335x.dap enabledError: JTAG-DP STICKY ERRORError: Could not initialize the APB-AP*Does anyone have any idea about this error? and do i need to do anything else in BBB apart from installing P2 header? Please let me know if i am doing anything wrong. Thanks in advance.
