That's the issue I "reported" on IRC yesterday. Since Debian's pastebin expires I put \
this into the issue tracker.

** [tickets:#201] dpmv8_dpm_prepare(): Timeout waiting for dpm prepare when calling \
virt2phys**

When tracing an imx8 board running a linux kernel I'm seeing the following when \
calling virt2phys:
```
Debug: 502 26591 command.c:143 script_debug(): command - ocd_command ocd_command type \
ocd_virt2phys 0x10000
Debug: 503 26591 command.c:143 script_debug(): command - virt2phys ocd_virt2phys \
0x10000
Error: 507 27593 armv8_dpm.c:179 dpmv8_dpm_prepare(): Timeout waiting for dpm prepare
Debug: 508 27593 command.c:642 run_command(): Command failed with error code -4
User : 509 27593 command.c:705 command_run_line():
```
The same happens when trying to attach a remote gdb (I just noticed that it's simpler \
to reproduce with virt2phys).
Also all CPU cores are up ``target`` shows:
```
> targets
TargetName Type Endian TapName State
-- ------------------ ---------- ------ ------------------ ------------
0* imx8mq.a53.0 aarch64 little imx8mq.cpu running
1 imx8mq.a53.1 aarch64 little imx8mq.cpu examine deferred
2 imx8mq.a53.2 aarch64 little imx8mq.cpu examine deferred
3 imx8mq.a53.3 aarch64 little imx8mq.cpu examine deferred
```
The used JTAG debugger is a Olimex ARM-USB-TINY-H. The full log is attached. The \
board config used is:
```
transport select jtag
adapter_khz 1000
reset_config trst_and_srst
adapter_nsrst_delay 70
set CHIPNAME imx8mq
set CHIPCORES 4
source [find target/imx8m.cfg]
```
very similar to NXPs EVK.
