Hi all, I need to debug the Beaglebone Black using JTAG. I got a TI LaunchPad CC1310. Launchpad has a XDS110 debugger with a (ARM - not sure) 10 pin JTAG out which can be used to debug external targets. The Beaglebone has a cTI 20 pin JTAG interface. Pin layouts for the ARM10 and cTI20 is given here.
http://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html#connector-information Can we map the pins, point to point without adapters to debug the BBB using Launchpads's XDS110? Following is what I came up with just refering the above given pin layouts. *ARM10 to cTI20* 1==5 (VTRef/VCC) 2==1 (SWDIO/TMS) 3==8 (GND) 4==9 (SWCLK/TCLK) SWDCLK(9) and TCK(11) are separate in cTI 5==10 (GND) 6==7 (SWO/TDO) 7 KEYED 8==3 (NC/TDI) 9==12 (GNDDetect) 10==15 (nRESET) Will this work? (EMU pins are not used here) Also I found a discussion in TI' forum which says, "Controlling the EMU0 and EMU1 signals, which are mandatory to place the AM335x in debug mode." https://e2e.ti.com/support/processors-group/processors/f/processors-forum/777331/am3358-how-to-evaluate-if-a-jtag-chain-works-correctly Also the hardware Mod for libdebugger in RTEMS connects the SWO/TDO(7) to the EMU0(13). https://docs.rtems.org/branches/master/user/bsps/bsps-arm.html#debugging-using-libdebugger My Project Proposal: https://docs.google.com/document/d/1CN3ri7g6NJeFPb5h8y4smr1aziGWyXbiiXUsFMhdUu4/edit?usp=sharing Best regards, Husni Faiz.
