Hi,

i want to use a recent Linux kernel as an updater linux for Mfgtool on custom MX28 board. I succeeded to port the FSL_UTP_UPDATER into Kernel 4.2.5, but the performance is bad (FSL 2.6.35 takes 4 minutes and Kernel 4.2.5 takes 11 minutes).

Any ideas what could be the reason for this?

I solved it. It was a combination of multiple issues:

  • suboptimal Kernel config
  • wrong version of FSL updater
  • missing DDR support in MMC driver
  • disabled streaming in Chipidea UDC driver

Hi Stefan

FSL 2.6.35 and 3.0.35 (please check attached Linux Manuals USB Chapters)

use ARC USB Driver, while 4.1.15  - CHIPIDEA USB Driver, so probably

this may be a reason.

Best regards

igor
