KE06Z Sim Driver Missing - Need UID

stevenlutz — Sat, 04 Dec 2021 02:39:03 GMT

I have realized that the sim driver (fsl_sim) isn't available in mcuxpresso for the MKE06Z and therefore accessing the UID of the chip isn't doable using the SIM_GetUniqueIdfunction as listed in the API here: https://mcuxpresso.nxp.com/api_doc/dev/1390/a00037.html#ga3691d99318793509be2fdc198ec7fd9e

Please advise on how I should move forward from here. Thank you

Hi @stevenlutz ,

This function read register at 0x4004_8018, named SIM_UUIDL. You can read it by yourself.

Thank you for the reply.
the SIM_UUIDL that you mentioned is only part of the UUID right? Or does that call the entire value?

Hi @stevenlutz ,

In the link you provided, it shows the return value of SIM_GetUniqueId (sim_uid_t *uid).

The sim_uid_t is defined as below

as mentioned in my original post, SIM_GetUniqueId() isn't a valid fucntion in my case. it seems that I need the SIM driver which isn't available.

Please advise on how to call this through the SDK
Thank you

Hi,

Use this instrument

uid=(*(unsigned int*) 0x40048018);

It seems no other function can read UID in SDK driver.
