Build problems

[khumarahn]

Hi, I tried to follow the linux building instructions in https://github.com/OLIMEX/DIY-LAPTOP/blob/master/SOFTWARE/A64-TERES/scripts/readme.md

I am not an expert at all. I have a few comments/questions:

• I guess that "Getting source code" section needs to be updated with the new location. Why is arm trusted firmware not mirrored in olimex repo?
• There is a requirement for gcc-4.7-arm-linux-gnueabihf toolchain, seems that it is only used in u_boot-new. Can somebody comment? Why armhf when everything else is aarch64? Why gcc-4.7? It does not seem to be needed upstream.
• ./build_uboot.sh fails with ./build_uboot.sh: line 29: ../sunxi-pack-tools/bin/update_boot0: No such file or directory I updated sunxi-pack-tools with the newer https://github.com/longsleep/sunxi-pack-tools, and it worked.

(EDIT):

• I had to install dos2unix https://waterlan.home.xs4all.nl/dos2unix.html, and also fakeroot, which weren't mentioned in the instructions. Though, I am not on ubuntu where they may come by default.

Also,

• ./make_simpleimage.sh teres.img 1000 ./linux-a64-3.10.104-1.tar.xz fails with

  Add mtools_skip_check=1 to your .mtoolsrc file to skip this test

Here I am not sure what's going on. Is it safe to add mtools_skip_check=1 to .mtoolsrc?

Hi Alexey, since we need 32 bit SPL/boot0 to get u-boot running/64 bit compiler exeeds 32k size of boot0/, we must use 32 bit compiler. Did you clone proper sunxi-pack-tools branch /this branch is forked from longsleep, as working/.

Best regards, Dimitar

ok, thanks for the explanation about the 32 bit compiler. I hope that the requirement for the old gcc-4.7 can be lifted at some point.

I didn't quite understand you about sunxi-pack-tools. I couldn't make work the version from here https://github.com/OLIMEX/DIY-LAPTOP/tree/master/SOFTWARE/A64-TERES/sunxi-pack-tools (error is in the first post). Maybe it needs to be updated with a newer one from longsleep's repo?

Something else missing in the instructions:

# cat /etc/udev/hwdb.d/teres_kbd.hwdb 
evdev:input:b0003v15BAp003C*
  KEYBOARD_KEY_7006f=brightnessdown
  KEYBOARD_KEY_70070=brightnessup

Readme is up to date, and i think everything should work as expected.
