[aleksanderbiryu]

Hello.

I want create encrypted linux image for ls1046a, then copy this image on flash.

Before booting, decrypt this image use "blob dec" u-boot command and then boot linux.

What tool can I use to create encrypted linux image on x86 host?

Hello Aleksander Biryukov,

Please refer to the following Encap boot commands under u-boot.

nand read <uImage DDR> <uImage NAND> <uImage size>
esbc_blob_encap <uImage DDR> 0x10000000 <uImage size> 0x11223344556677889900aabbccddeeff
nand erase <encapsulated uImage NAND> <encapsulated uImage size>
nand write 0x10000000 <encapsulated uImage NAND> <encapsulated uImage size>

Please refer to the following decap boot commands under u-boot.

nand read <encapsulated uImage DDR> <encapsulated uImage NAND> <encapsulated uImage size>
esbc_blob_decap <encapsulated uImage DDR> 0x10000000 <uImage size>
0x11223344556677889900aabbccddeeff

Have a great day,
