Added LPUART_CTRL = 0; in hal_prepare_boot() to disable the UART controller before jumping to the application. Previously, only the TX completion was waited for, leaving the UART in an initialized state that could interfere with the application's UART reinitialization.
When building with SIGN=NONE, the test-app failed to link due to undefined keystore references. Fixed by:
Wrapping keystore function calls in app_s32k1xx.c with #ifndef WOLFBOOT_NO_SIGN
Making keystore.o conditional in the test-app Makefile (ifneq ($(SIGN),NONE))
Added --trigger-magic flag to nxp-s32k142-flash.sh for use with --test-update. This automatically includes the "pBOOT" trigger magic bytes at the end of the update partition, causing the update to start automatically on first boot (matching behavior of other ports like nrf5340 and va416x0).
Usage: ./tools/scripts/nxp-s32k142-flash.sh --test-update --trigger-magic
