Is there a register on the I.MX8M that distinguishes between Silicon Rev. A and B (rev 1.0 and rev 1.1)? EB00870 (i.mx 8m Mask Set 1N14W to 2N14W Migration Guide) refers to a "Silicon version register address" at 0x30350040, but there doesn't seem to be a reference to it in the Reference Manual.
Aldo,
Our I.MX8MQxA boards report back:
Hello,
Sorry for the confusion,
Rev 1.0 ---> A0 chips
Rev 2.0 ---> B0 chips
Rev 2.1 ---> B1 chips
Hope this helps,
Best regards,
Aldo.
Hello,
The mscale B1 uses OCOTP_HW_OCOTP_READ_FUSE_DATA register for chip id, it returns 0xff0055aa.
Also, you may take a look to the part marking of the device you are using i.e.
MIMX8MQxxxxxxxA -----> Rev 1.0
MIMX8MQxxxxxxxB -----> Rev 1.1
This information is available in the product datasheet Figure 2. Part number nomenclature
Hope this helps,
Best regards,
Aldo.
