DeoNanoSoc: sources problem to make whole SD card!

Thanks, Jumaah. In the meanwhile we have made some "progress".

I finished the whole chain

KERNEL : After angstrom 2018.06 compiling (7 hours) I found a bunch of files inside ../deply/glibic/images/cyclone5

I prepared a folder with all requested files (Preloader-mkpimage.bin,soc_system.rbf,soc_system.dtb,u-boot.img,u-boot.scr,zImage, rootfs archive compressed and rootfs expanded)

zImage file is only 4.7 MB (i found same dimensions on reference SD card, so it should be right...)

ROOTFS: I try to decompress rootfs archive (Angstrom-gsrd-console-image..rootfs.tar.gz) , and I obtained a rootfs large folder

Then I launch python make_sd_image.py script

It runs fine and I obtained my SD IMAGE (!)

Attempting to boot Terasic DeoNanoSOc, monitor on uart says : (rbf file is loaded correctly, I think..)

READING U-BOOT.IMG

SPL: ERROR READING IMAGE U-BOOT, ERR -1

Uart DIsplay is attached here ..

MY GOAL IS TO UNDERSTAND WHOLE OPERATION CHAIN to obtain a booting sd card, in order to reproduce this procedure on our Self-developed Cyclone5 Card... SO I need to put my RBF and my preloader/u-boot to test my hardware: but first I must be confident that I can make the process running well on Terasic card... this is an hard work for me (I not have linux soc experiences before current work)

Thanks for any tips!
