** [tickets:#344] Error executing event examine-end on target stm32f1x.cpu**

trying to program the DAPLink ([https://github.com/ARMmbed/DAPLink](https://)) bootloader using a DAPLink (STM32F103 based https://daplink.io/) as programmer with OpenOCD.

works ok (bootloader written) - although the error appears - when using the .hex file:
```
$ openocd -d0 -c "source [find interface/cmsis-dap.cfg]; transport select swd; source [find target/stm32f1x.cfg]" -c "init; reset init; flash write_image erase stm32f103xb_bl_crc_0257_16mhz.hex; verify_image stm32f103xb_bl_crc_0257_16mhz.hex; exit"

```

it seems like init fails partly and OpenOCD tried to program the .bin file to the wrong location. unfort i am no TCL expert, so i've no clue what is going on / missing.

not sure, if this helps, but the .hex file starts like this:
```
:04000005080004F9F2
:020000040800F2
:10000000004F0020F90400084505000835060008E7
:100010004D05000851050008550500089A90FFAFEE
:10002000939D939B0899969701010000590500083C
```
and ends in:
```
:10BBD000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF75
:10BBE000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF65
:10BBF000FFFFFFFFFFFFFFFFFFFFFFFF4C103CFFBA
:00000001FF
```
