flash / ram sizes for custom boards

[dave]

Hi,

When creating custom boards using the nrf connect vs code extension (ncs 2.7 with nrf9160)  The flash and ram values in the <board>.yml and <board>_ns.yml file are different

test_ns.yml

identifier: test/nrf9160/ns
name: Custom Board auto generated by nRF Connect for VS Code
vendor: test
type: mcu
arch: arm
ram: 128
flash: 212
toolchain:
  - gnuarmemb
  - xtools
  - zephyr
supported:
  - gpio
  - i2c
  - pwm
  - watchdog
  - netif:modem
  - uart
  - spi

test.yml

identifier: test/nrf9160
name: Custom Board auto generated by nRF Connect for VS Code
vendor: test
type: mcu
arch: arm
ram: 88
flash: 1024
toolchain:
  - zephyr
supported:
  - i2c
  - pwm
  - watchdog
  - netif:modem
  - gpio
  - uart
  - spi

Is this expected?  Which values are the correct ones to use?

Hi,

See Processing environments.

_ns is with TF-M, and then TF-M uses parts of the memory.
