Starterware/AM3352: AM3352 MLO MMU Cache Enable

Part Number: AM3352

Tool/software: Starterware

Hi Team,

  My customer is facing a NAND read speed issue.

  They're using the AM3352 with StarterWare_02_00_01_01, the booting device is NAND flash. Now they have the application almost done, the main issue is that the booting time is somehow longer than expected. When deep investigating, they found that the time that MLO read the app is longer, 1.9 second for 200K. 

So now they are trying to consider to enable the MMU/CACHE for speeding up the NAND read process in the MLO stage. However, the MLO is always failed when enabling the MMU & CACHE. So I would like to ask whether it is possible to enable the MMU & CACHE in the MLO stage for speeding up the NAND read process?
