atomic DMA coherent pool is too small

Hi guys,

I used the JekPack 2.3.1 for our products.
Sometimes, Kernel was showing error msg :

How to fix this issue?


Alleen Wang,

Few questions.

  1. What is your product for? Did you follow the OEM DG for hardware?

  2. Did you modify kernel driver?

  3. Is it possible to use latest jetpack for your product?

This is for a TK1, but should apply. You may be interested in this:

Excerpt from the TK1 example using arguments to the kernel command line at boot:
