OpenOCD 0.10.0 + JTAGKey

Postby Hogehoge » Thu May 18, 2017 5:21 pm

At OpenOCD 0.10.0, Amontec JTAGKey is unable to use it is troubled.
At 0.9.0, it was usable.

For 0.9.0, I used the 'ft2232' interface (interface/jtagkey.cfg),
same 0.9.0 uses the 'ftdi' interface (interface/ftdi/jtagkey.cfg).
For 0.10.0 it is necessary to use the 'ftdi' interface.

The target is Raspberry Pi (Zero / 1).

bcm2835.cfg
Code: Select all
# BCM2835

if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME bcm2835
}

if { [info exists CPU_TAPID ] } {
set _CPU_TAPID $CPU_TAPID
} else {
set _CPU_TAPID 0x07b7617F
}

jtag_ntrst_delay 400
reset_config trst_only
adapter_khz 1000

jtag newtap $_CHIPNAME arm -irlen 5 -expected-id $_CPU_TAPID

target create $_CHIPNAME.arm arm11 -chain-position $_CHIPNAME.arm
$_CHIPNAME.arm configure -event gdb-attach { halt }

I don't think 'ft2232' and 'ftdi' are compatible.
Can you still use the ft2232 interface at 0.10.0?

Thanks.
