Hi Simon, I get what you mean, Simon. I will do the following changes: (1) I will change blob to blob-ext entry in binman dts node for all input files. - uboot_blob: blob { + uboot_blob: blob-ext { (2) I will revert all changes in Makefile to allow binman to run by default. And, I will remove "make fit-itb". Yes, I saw that it will report warning instead of error. > - Makefile - builds the binaries BINMAN all Image 'main-section' is missing external blobs and is non-functional: blob-ext Some images are invalid (3) We will directly use binman command to generate the fit image. Binman will report error if the input file doesn't exist. > - binman - put it all together into images bash-4.1$ ./tools/binman/binman build -u -d u-boot.dtb -O . -i u-boot bash-4.1$ ./tools/binman/binman build -u -d u-boot.dtb -O . -i kernel binman: [Errno 2] No such file or directory: 'Image' Thanks, Siew Chin > > > > > Thanks, > > Siew Chin > > > > > > > -----Original Message----- > > > From: Simon Glass <s...@chromium.org> > > > Sent: Saturday, December 19, 2020 10:29 AM > > > To: Lim, Elly Siew Chin <elly.siew.chin....@intel.com> > > > Cc: U-Boot Mailing List <u-boot@lists.denx.de>; Marek Vasut > > > <ma...@denx.de>; Tan, Ley Foon <ley.foon....@intel.com>; See, Chin > > > Liang <chin.liang....@intel.com>; Simon Goldschmidt > > > <simon.k.r.goldschm...@gmail.com>; Chee, Tien Fong > > > <tien.fong.c...@intel.com>; Westergreen, Dalon > > > <dalon.westergr...@intel.com>; Gan, Yau Wai <yau.wai....@intel.com> > > > Subject: Re: [v4 16/17] arm: socfpga: soc64: Enable FIT image > > > generation using binman > > > > > > Hi Siew, > > > > > > On Thu, 17 Dec 2020 at 20:29, Siew Chin Lim > > > <elly.siew.chin....@intel.com> > > > wrote: > > > > > > > > Add new build target "fit-itb" for FIT image generation. > > > > > > > > In preparation to support Vendor Authorized Boot (VAB) for Intel > > > > SOC64 device in near future.
