From my Linux workstation I did screen /dev/ttyUSB0 115200Īnd then I powered up the DockStar. I only had a 5V usb-ttl cable, but it works. : today I opened up the DockStar and connected a usb-ttl cable to the internal serial port. The connector of the DockStar looks like this seen from the front (with the ethernet jack away from you): Which is connected to a cable with the following connector: : config of usb-serial cable: 1 x TTL-232R-5V with the following pinout: After modifying the dockstar.cfg file a openocd -f dockstar.cfg Info : accepting 'telnet' connection on tcp/4444 Info : feroceon.cpu: hardware has 1 breakpoint/watchpoint unitĮrror: unexpected Feroceon EICE version signature Warn : Bypassing JTAG setup events due to errors Info : This adapter doesn't support configurable speedĮrror: JTAG scan chain interrogation failed: all zeroesĮrror: Check JTAG interface, timings, target power, etc.Įrror: Trying to use configured scan chain anyway.Įrror: feroceon.cpu: IR capture error saw 0x00 not 0x01 Warn : use 'feroceon.cpu' as target identifier, not '0' Trst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain connect_deassert_srst Srst_only separate srst_gates_jtag srst_open_drain connect_deassert_srst Info : only one transport option autoselect 'jtag' Warn : Adapter driver 'buspirate' did not declare which transports it allows assuming legacy JTAG-only Write new image to DockStar]$ openocd -f.
