Task aware debug support for Threadx in Openocd

Community Development Platforms

Hi,

I’m breaking my head to make task aware debug on Cypress Superspeed exlplorer kit. Its an arm926ejs core.

There’s eclipse sdk provided, but without the task aware support for threadx.

By task awareness I mean it should be able to show me all the threads call stack in the eclipse or in gdb “info threads” command should work.

At present, I can only see the thread which is currently executing. There’s no way to check the call stack of other threads.

Below is the openocd cf file used:

#
# USB-Serial IC (CY7C65215) JTAG
#
# 
#

gdb_port 3333
interface openjtag

# Target:    CY FX3 ARM926ejs

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
}

Now, I’ve tried by enabling -rtos auto option but does not seem to work.

My question is that does openocd support multiple threads for Threadx rtos ?

Cheers
