When i debug the code below, then my JLink can no longer to connect with the mcu.
1. code
/* Reprogram secure byte in Flash configuration field */
#if (FSL_FEATURE_FLS_HAS_PROGRAM_PHRASE_CMD == 1u)
address = 0x408u;
size = FTFx_PHRASE_SIZE;
#else /* FSL_FEATURE_FLASH_HAS_PROGRAM_LONGWORD_CMD == 1u */
address = 0x40Cu;
size = FTFx_LONGWORD_SIZE;
#endif /* FSL_FEATURE_FLS_HAS_PROGRAM_PHRASE_CMD */
ret = FlashProgram(&flashSSDConfig, address, size, unsecure_key, pCmdSequence);
if (ret != FTFx_OK)
{
return ret;
}
2. error log
