Hi community,

Our partner want to access to i.MX6S ENET_MMFR register to read/write Ethernet PHY after boot kernel.

They have confirmed it is possible by u-boot, but not confirmed after boot kernel (L3.0.35_4.1.0_ER) because don't know how to do it.

Could you let me know whether it is possible and how to do it if they can?

Best Regards,

Satoshi Shimoda

Hi Satoshi

probably one can use memtool:

Attached document sect.34.6 "Using the Memory Access Tool"

shows details.

Best regards
