Re: [dts] [patch V1] fix retrieve_eeprom in userspace_tools test suite

["Liu, Yong" <yong.liu@intel.com>]

Hi Yufen,
We cannot assume tester and dut are using the same platform. Now what we can grantee is that DTS is running on the tester.
So all temporary used file generated on DUT need to be copied to tester and then analyze the result. 

Regards,
Marvin
