If you have issues using OpenOCD 0.8.0, try these:
1. rebind the adapter to the WinUSB driver. See this link for instructions.
2. copy the following config into a file called fx3.cfg and put it into the [openocd_install_dir]/scripts/target folder
############################################
# Target: Cypress EZ-USB FX3 ARM926EJ-S #
############################################
if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME fx3
}
if { [info exists ENDIAN] } {
set _ENDIAN $ENDIAN
} else {
set _ENDIAN little
}
if { [info exists CPUTAPID] } {
set _CPUTAPID $CPUTAPID
} else {
set _CPUTAPID 0x07926069
}
# Reset configuration
reset_config trst_and_srst srst_pulls_trst
adapter_nsrst_delay 200
jtag_ntrst_delay 200
jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_CPUTAPID
########################
# Target configuration #
########################
set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME arm926ejs -endian $_ENDIAN -chain-position $_TARGETNAME -variant arm926ejs
adapter_khz 1000
3. run openocd.exe as follows:
openocd-x64-0.8.0.exe -f interface/ftdi/olimex-arm-usb-ocd-h.cfg -f target/fx3.cfg

Hi,
How do you debug threads?

Can you elaborate on what you meant by "debug threads"? What do you want to be debugged in the threads?

I mean:
1. view list of running threads (gdb: info threads)
2. switch between threads and look: what is instruction/function run now, what registers (gdb: thread #/frame #/bt)
3. view thread structures and so on.
Currently if I stop core SP and PC registers may points to random location and I can see backtrace only for current stack (that pointed by SP).
Threads is a ThreadX entity. OpenOCD supports ThreadX but only for Cortex-M3 and Cortex-R4 cores. Tomorrow I will try my patched OpenOCD version with arm926ejs support. May be it will be work 🙂
