Hi! I'm using an S32K312 together with HSE_B FW (2.6.0).
Right now I'm trying to import and update a AES key into key catalogue through HSE.
The first time when I set the key I receive HSE_SRV_RSP_OK from HSE with the following key info:
key_info.keyType = HSE_KEY_TYPE_AES;
key_info.keyFlags = (uint16_t)(HSE_KF_USAGE_ENCRYPT | HSE_KF_USAGE_DECRYPT | HSE_KF_USAGE_SIGN | HSE_KF_USAGE_VERIFY);
key_info.keyBitLen = 128;
key_info.keyCounter = 0;
I have verifed that the key is correct inside the HSE with AES calculations on the HW and external testing.
From my understanding I should be able to update the key value if I update keyCounter to exactly 1 from the previous key, which in my case should be 1 (I have tried multiple other numbers as well). But I receive response HSE_SRV_RSP_NOT_ALLOWED.
The key catalogue is formatted to be HSE_KEY_OWNER_CUST, AES and correct size otherwise I wouldnt be able to import it in the first time.
I know that I'm CUST SuperUser as well (Hse Status = 0xb60).
I dont know what can be wrong? I dont set write protection and debug protection... any ideas?
