Closed neithanmo closed 2 years ago

neithanmo commented 2 years ago

The bootloader and uboot should be validated before booting the image, for this keys and certificates are used.

for the dk2 build, this has been already implemented and tested in a close board, in theory it is ready to be tested on imx board, the missing part is to fuse keys on imx and check that it boots a signed image. for dk2 see #29 and #32 and for imx see #32

Should I test it in my dk2 board? What is missing here?

carlosala commented 2 years ago

Tested and working properly in dk2. Closing!
