RT1050 UUID

[ffloree]

Does RT1050 have UUID (instead of UID)? if it does, which registers I can get it from?

I know RT685 has it, see the UM11147 Section 4.5.5.52, but I didn't find it in RT1050 reference manual, it just mentions a 8-byte UID which can be read from OCOTP->CFG0 and OCOTP->CFG1, but I don't think it's the standard 16-byte UUID following rfc4122 https://www.rfc-editor.org/rfc/rfc4122 .

UUID is from the fuse 0x410 and 0x420. We can use the shadow registers to get its value.For RT1050, you can use the following code to get the UUID. 

UUID_L = *(uint32_t *)0x401f4410;

UUID_H = *(uint32_t *)0x401f4420;

Hi @ffloree ,

Yes, there is a thread on similar topic, and you may refer to https://community.nxp.com/t5/i-MX-RT/Read-UID-Unique-ID-on-i-MXRT-RT1050/m-p/1202637 for details.

You may refer to chapter 22 in the RM for more details.

Hope that helps,

Have a great day,
Kan

@Kan_Li ,

Thank you, I've seen this ticket, it talks about the Unique ID instead of Universally Unique ID. You provided the 8-byte (reg0x410 and reg0x420) data is not the UUID either. Correct me if I'm wrong.
