Hi everyone, I'm trying to implement the SPL falcon mode on an embedded board based on the IMX6 SoC. I have succeeded recently in implementing it for a legacy Image and now i'm trying to implement it for a fitImage... after setting the appropriate configs, when I try now to boot with a fitImage (packaging the kernel+initramfs+dtbs), I started getting the error "Bad FIT standalone image format!" :
... ## Loading standalone from FIT Image at 177fffc0 ... Wrong FIT format: no description Bad FIT standalone image format! Raw boot image support not enabled, proceeding to other boot methods spl: ext: failed to parse image header spl_load_image_ext: error reading image fitImage, err - -22 ...
Now If I double-check the content of the fitImage (compared to my source .its) with "mkimage -l" or "iminfo" on u-boot, I can see that every node contains the "description" property as requested by the SPL, and if I use the same fitImage with u-boot, everything works as expected.. the bootm routine recognizes the fitimage and parses its content correctly.
So, the problem apparently is not with the fitImage but with the SPL and the way it is handling it.
To enable FIT support for u-boot and the SPL I'm setting the following configs: CONFIG_FIT=y CONFIG_SPL_FIT=y CONFIG_SPL_LOAD_FIT_FULL=y
When analyzing the issue, I found out that the SPL and u-boot are using the same functions (for handling the fitImage) from image-fit.c and the same library lib/libfdt. So I wonder what can go wrong inside the SPL to give such output ?
Also, I noticed that there is a second config by the name CONFIG_SPL_LOAD_FIT and I would like to know what is the addition in using CONFIG_SPL_LOAD_FIT_FULL instead ? (for me, only the second one is supported, as I'm loading the fitImage and the SPL args from an EXT4 partition. There is no implementation for CONFIG_SPL_LOAD_FIT in spl-ext.c)
I would really appreciate your help ! Thank you in advance -- Abder
