west flash with --hex-file param does not find hex file

[zafersn]

Hi,

I am trying to flash merged.hex file which is located C:\zephyrproject\wsc\hello_world\build_u575\zephyr\merged.hex and I tried all combinations of west flash command to flash merged hex. But I got the error FATAL ERROR: download file merged.hex does not exist

i am using a st board with stm32cubeprogrammer.

for example, these are the combinations I used to flash

c:\zephyrproject\wsc\hello_world>west flash -d build_u575 --hex-file zephyr/merged.hex
c:\zephyrproject\wsc\hello_world>west flash -d build_u575 --hex-file merged.hex
c:\zephyrproject\wsc\hello_world>west flash -d build_u575/zephyr --hex-file merged.hex
c:\zephyrproject\wsc\hello_world>west flash -d build_u575/ --hex-file merged.hex

anyway no luck.

but when I run west flash -d build_u575, it flashes the zephyr.signed.hex

here is the runner output:

c:\zephyrproject\wsc\hello_world>west flash -d build_u575 --hex-file zephyr/merged.hex
c:\zephyrproject\wsc\hello_world>west flash -d build_u575 --hex-file merged.hex
.
. The result is the same like this below for the rest of the commands
.
-- west flash: rebuilding

I found a runners.yaml file in C:\zephyrproject\wsc\hello_world\build_u575\zephyr and noticed that there are variables:

 # Build outputs:
  elf_file: zephyr.elf
  hex_file: C:/zephyrproject/wsc/hello_world/build_u575/zephyr/zephyr.signed.hex
  bin_file: C:/zephyrproject/wsc/hello_world/build_u575/zephyr/zephyr.signed.bin

is there any simple way to edit these paths in project cmakelists.txt?

I only found this may help but it seems quite complicated (https://github.com/zephyrproject-rtos/zephyr/blob/main/cmake/flash/CMakeLists.txt)
