<stikonas> vagrantc: I saw you were trying to build bl31.elf from source some time ago and hitting `.pmusram' will not fit in region `PMUSRAM' error. Have you managed to solve it?
<stikonas> so ld says "region `PMUSRAM' overflowed by 104 bytes"
<vagrantc> stikonas: no, haven't tried since
<stikonas> ok :(
<stikonas> well, my overflow is 30 times smaller than yours, but still a bit too much
<vagrantc> probably some change in toolchain
<stikonas> probably
<stikonas> I've tried gcc 4.9 and gcc 7
<stikonas> with exactly the same results...
<vagrantc> i was using gcc 8, i think ... binutils is also a likely place to look
<stikonas> well, I managed to cut about 20 bytes with -Os
<stikonas> can try some older binutils too
* vagrantc forgets what toolchains the atf documentation recommends
<vagrantc> i would guess some specific linaro toolchain or something
<stikonas> I didn't even see any documentation
<stikonas> maybe I should look there...
<stikonas> my toolchain is self compiled
<stikonas> well, to be more precise, crossdev ebuild on gentoo

<stikonas> should probably try linaro then...
<vagrantc> i was using debian sid's toolchain, but i guess i could try with the older version
<stikonas> hmm, linaro was using gcc 4.8
<vagrantc> or maybe try with guix, which allows for great flexibility in toolchain version selection
<stikonas> well, I'll see. If I manage to get it compile and boot, I can let you know
<vagrantc> cool
LargePrime has quit [Ping timeout: 272 seconds]
<vagrantc> i'll give a quick build test with the current debian stable release, too
<vagrantc> thanks for the reminder :)
<vagrantc> fwiw, rk3328 bl31.elf builds fine
<stikonas> well, that's good... I need rk3399 though :(
<stikonas> for rockpro64
<vagrantc> haven't actually *tested* any of these other than the allwinner ones
<vagrantc> successfully, that is
<stikonas> well, on my board I still have to use binary u-boot spl and this bl31.elf... u-boot image itself seems to boot
<stikonas> well, it boots grub2 :)... After that it's like desktop...
<vagrantc> yeah, i've got a firefly-rk3399 that needs it too
<vagrantc> well, how about that. builds successfully on debian stretch/stable.
<stikonas> oh, that's nice
<stikonas> should try on debian then...
<vagrantc> might also use different optimizations ... but that's some progress at least
<vagrantc> is the m0 firmware still needed separate from the bl31.elf?
<stikonas> I'm not there yet... no idea
<stikonas> well, I just started playing with u-boot...
<stikonas> before I was trying to get upstream kernel to build, moved rootfs to LUKS+ LVM :)
<stikonas> vagrantc: were you using debian on aarch64?
<stikonas> or crosscompiling?
<vagrantc> stikonas: cross-compiling
<stikonas> I think I'll try debootstrap first...
<stikonas> oh ok
<vagrantc> hmmm... would be interesting if a native build worked
<stikonas> well, you still need arm-none-eabi crosscompiler
<vagrantc> sure, but native for the rest
<stikonas> well I'll try... Probably tomorrow, it's getting late in my timezone
<vagrantc> been working on this on and off again for maybe 18 months now
<stikonas> so long...
<vagrantc> mostly off :)
vicencb has quit [Quit: Leaving.]
<stikonas> vagrantc: I compiled it now but simply using that bl31.elf didn't work...
<vagrantc> i am not surprised
<stikonas> well, yeah, I wasn't keeping my hopes too high
