Is there a document or command that list of all available EMC frequencies on the Jetson platforms? Like I would for the CPU/GPU frequencies?

Thanks

Not tried on Xavier, but you may try:

sudo ls /sys/kernel/debug/bpmp/debug/emc/tables/regular/

Hi Matthew, there is a table that lists the memory frequencies for the nvpmodel presets included in the L4T Documentation under ‘Clock Frequency and Power Management’ in the ‘Power Management for Jetson-Xavier Devices’ and ‘Max-Q and Max-P Power Efficiency’ section.

Here is the output of the command that HP mentioned above:

$ sudo ls /sys/kernel/debug/bpmp/debug/emc/tables/regular/
1065600  1331200  1600000  1866000  204000  2133000  408000  665600  800000
