Hello,
I am currently developing Secure Boot on the S32K3 series, and I have encountered an issue where I am unable to program via JTAG.
I would like to ask: when the device enters Recovery Mode, is it expected that JTAG cannot be used together with the IDE for direct programming?
Here are the test conditions:
1.HSE AB Swap is installed
2.ADKP is enabled
3.LifeCycle is set to OEM_PROD
4.Using Basic Secure Boot, with an intentionally incorrect GMAC TAG
5.IVT_AUTH is disabled
6.Before programming, ADKP was successfully unlocked using the official Python script
Could you please advise whether these settings would prevent JTAG programming in Recovery Mode, and if there are any recommended steps to resolve this issue?
Thank you for your support.
Best regards,
