Hello,
I have been getting the run around with no one wanting to giving me access to this software
Hmm, there is no FW you can get standalone. Either you order sample with FW from factory or you write your own HSM FW.
I am not sure about the ordering of secure sample, but you need to contact local vendor or NXP ask ask specifically for it.
I do not see any issue to get hand on them, as those are not new devices and there is already HSE-B module on new ones.
Have you sign NDA with NXP?
Best regards,
Peter
