Encrypted firmware via JTAG?

[luishs]

Hi.

I have already solved the problems with JTAG and SWD.

One more question, please:

To upload an encrypted firmware image to RT1020, can I use Jlink through JTAG, or do I have to do it via USB with MFG Tools?

Hello,

   To use encrypted boot the image should be loaded and run by boot ROM, using 

any available boot option. In this sense only the MFG may be used to work with HAB,

assuming other possible channels, such as JTAG are disabled or applied in secure

mode.  

Have a great day,

Yuri
