Using NCS 3.0.0
When placing the app slot 1 in external flash, mcuboot cannot open the flash area.
I am testing this with nrf54L15 + 8 MB SPI flash on the DVK.
This same issue occurs with nrf52840 + 2MB QSPI flash.
static partition config:
1641.pm_static.bl54l15_dvk_nrf54l15_cpuapp.mcuboot.ext_flash.yml.zip
