U-boot Hang at Authenticate Image from DDR

trongthinh — Thu, 13 Dec 2018 03:38:45 GMT

I am using u-boot 2016.03 on iMX6Dual (meta-freescale, branch pyro). I followed 2 documents (IMX Application trust Architecture, High assurance Boot Hab dummy) to enable secure boot and sign u-boot/kernel.

=> load mmc 1 12800000 zImage

And

=> hab_auth_img 12800000 600000

U-boot hangs here. Bellow is the log:

Authenticate image from DDR location 0x12800000...

My question is "What is the possible cause?" Is there any suggestion?

Hello,

Please try to get HAB log, using JTAG to read data from 0x00904000, size 0x0B80.

Have a great day,
Yuri

Hi Yuri,

The problem is script genIVT has some fixed values (Jump location, Self Pointer, CSF pointer). I did not change these values to the correct one for my kernel. I solved the problem by changing these values. Here is a script var-genIVT of someone on GitHub that helps me do the job faster.

Thank for your help!
