Hi @michael_yang,
I hope you are doing well
Both part number has the below differences.
MCIMX6Y2CVM05AB: 528 MHz, industrial grade for general purpose
MCIMX6Y2CVM08AB: 792 MHz, industrial grade for general purpose
According to the values written in the SPEED_GRADING[1:0] fuses, the frequency will be selected from the U-boot as mentioned in
soc.c file.
Hence No software changes are required.
The fuse SPEED_GRADING[1:0] can be referred from the
Table 5-9. Fusemap Descriptions from the reference manual
IMX6ULLRM.
Thanks & Regards,
Dhruvit Vasavada
