tests: arm: adjust test for relocated rom (a1e3083d) · Commits · Wenxi XU / zephyr

Add a memory barrier to make sure write to NVIC is completed before continuing with the test fails in scenarios where CONFIG_ROMSTART_RELOCATION_ROM is enabled for boards like MPS3 Corstone310 and k_sem_take is called before the isr's are called. Signed-off-by:
