Ported S32K344_HSE_FW_INSTALL example to S32K342. Build OK, S32K342.mac reset completes, but code traps into Default_Handler (BusFault/HardFault) <STRONG>before reaching main</STRONG> — fails during startup. Pink is 0.13.0_2.40.0 FULL_MEM. What startup/linker changes are needed for S32K342?</P> Thu, 25 Jun 2026 07:20:38 GMT https://community.nxp.com/t5/S32K/S32K342-HSE-installation-issues/m-p/2386164#M59501 Jay9 2026-06-25T07:20:38Z https://community.nxp.com/t5/S32K/S32K342-HSE-installation-issues/m-p/2386394#M59510 <P>It could be possibly caused by used library (semihosting or so..) as I have recently faced similar issue.
