HAB & elf files

Hello,

 

I was wondering to what extent the imx280 ROM bootloader needs the ELF file in a bootstream order to function and is

there any way around it?

 

We are using HABv4 (imx280) and for a single image it seems to require both the bin file and the elf file in the bd file.

I understand the necessity of the bin file in order to cover padding for the signing, but why is the elf file necessary

if we're specifying the load/call addresses ourselves in the bd file ?

It doesn't seem to work in a cold boot. It only works if we first load a 'proper' image and then load the elf-less bootstream

in USB recovery without removing power. Might be due to residual data in SRAM.

 

Thanks,

 

Filip Aben
