I am unsure here, if it makes sense to overwrite flash.bin with the binary which contains SPL and u-boot.itb. May others want to use them (as I currently use them for signing them)
I thought about that too. Frieder suggested I use a different name for the SPL file, such as spl.bin.
I am concerned that renaming flash.bin to spl.bin may break i.MX8MM targets that do not use binman, such as the verdin-imx8mm board.
Hmm... okay, but I do not understand why spl code is named flash.bin than?
spl.bin seems better to me.
Why not imx-boot as image name as in NXP sources?
NXP U-Boot also generates the final binary called "flash.bin"
What do you mean with "final binary"? The binary which contains SPL and u-boot (and all other needed binaries)?
If so, is this really called flash.bin? So *same* name as "SPL only" code? I could not believe this...
NXP code does this not for all imx8 derivates, see comment:
https://github.com/Freescale/meta-freescale/blob/master/recipes-bsp/u-boot/u...
But yes, the container is named "flash.bin"...
My main motivation for sending this RFC patch is to avoid imx8mm-evk breakage when people upgrade to U-Boor 2021.07.
U-Boot 2021.07 is broken? Or do you mean 2021.10?
Ah, *now* I got it commit "8996e6b7c6a1" introduced a SPL based "flash.bin" through arch/arm/dts/imx8mm-evk-u-boot.dtsi:
+ flash { + mkimage { + args = "-n spl/u-boot-spl.cfgout -T imx8mimage -e 0x7e1000"; + + blob { + filename = "u-boot-spl-ddr.bin"; + }; + }; + };
-> now we have a "flash.bin" with SPL only code and a "flash.bin" Makefile target which produces "flash.bin" which is a container of SPL, U-Boot, dtb, atf, ... and may much more binaries...
:-(
Added Peng to cc, as he did this conversion for imx8mm-evk-u-boot.dtsi
Prior to 2021.07: only flash.bin was required. Yocto recipe, for example, will no longer produce a bootable image after the upgrade to 2021.07. This is the breakage I would like to avoid.
I vote for renaming flash.bin (in SPL case) to spl.bin. It seems to me there are many imx8*-u-boot.dtsi file now which use this part:
+ flash { + mkimage { + args = "-n spl/u-boot-spl.cfgout -T imx8mimage -e 0x7e1000"; + + blob { + filename = "u-boot-spl-ddr.bin"; + }; + }; + };
But may this rename is no problem, as all boards use the "flash.bin" container?
I don;t know...
bye, Heiko
