Tool/software:
Dear Team member,
We are considering adopting the DRA714.
The maximum frequency of this chip's MPU is 600MHz.
DRA71x Infotainment Applications Processor datasheet (Rev. G)
■Question
When configuring to 400MHz or 300MHz,
is that still within TI's guaranteed operating range?
According to previous posts,
the frequency can be adjusted by modifying the device tree included in the SDK as shown below.

We understand that support may be limited because this chip is an old chip,
and we sincerely apologize for asking multiple questions.
we appreciate your help and look forward to your reply.
