I also have SAME54 Xplained board and flashing also worked for that.
What do you mean by it wasn't removed from anywhere - I couldn't find it from
latest version.

** [tickets:#224] samde53 openocd 0.10.0 Error: Failed to read memory at
0x400e0944**
**Status:** new

I tried to flash atsame53j18 with openocd 0.10.0. I used following .cfg file:
~~~
# Atmel-ICE JTAG/SWD in-circuit debugger.
source [find interface/cmsis-dap.cfg]
transport select swd
# Chip info
set CHIPNAME at91same53j18
source [find target/atsamv.cfg]
# this disables Failed to read memory at 0x400e0944
# if program is not following
gdb_memory_map disable
reset_config srst_only
~~~
There is whole command with following output.
~~~
openocd -f myopenocd.cfg -c "program build/$(PROJECT).elf verify reset exit"

It is possible to load elf to the board if I do this and then attach arm gdb:
~~~
>>openocd -f myopenocd.cfg
>>arm-none-eabi-gdb some.elf
(gdb) load some.elf
(gdb) run
~~~
However as soon as flash info is requested it fails:
~~~
(gdb) monitor flash list
{name atsamv base 4194304 size 0 bus_width 0 chip_width 0}
(gdb) monitor flash info 0
SWD DPIDR 0x2ba01477
Failed to read memory at 0x400e0944
auto_probe failed
~~~
What might cause this behaviour?
