|
|
Team,
I'm trying to get a Raspberry Pi 3 to work in 64 bit mode. I've got lots of bits to put together, including some userspace things in a cross root.
So far I have
a 3.3v USB to serial 'dofer'
a 64 bit Pi3 uboot
a 64 bit Pi3 kernel The idea being that uboot leaves the Pi in the right privilege level for the kernel to run and hands over to the kernel.
I get to interact with the Pi using minicom because thats about all that works in 64 bit mode so far.
I'm building as much userspace as possible with a cross dev toolchain. However one of the key packages - gcc fails.
The build log finishes with
Code: | /usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../libbacktrace/.libs/libbacktrace.a(state.o): Relocations in generic ELF (EM: 183)
/usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../libbacktrace/.libs/libbacktrace.a(state.o): Relocations in generic ELF (EM: 183)
../libbacktrace/.libs/libbacktrace.a: error adding symbols: File in wrong format | so its clearly using the wrong linker, which is then choking on an aarch64 ELF.
aarch64-armv8a-linux-gnueabi-emerge --info =sys-devel/gcc-5.3.0::gentoo
Build log
aarch64-armv8a-linux-gnueabi-emerge -pqv =sys-devel/gcc-5.3.0::gentoo
A pointer or two would be very welcome _________________ Regards,

Could you provide the kernel config and the uboot?
I would try to get a RPi3 buildroot image. There is nearly perfect cross compile support in it. With that staging point in 64 bit aarch userland we could get a 64bit gcc on gentoo _________________ // valid again: I forgot about the git access. Now 1.2GB big. Start: 2015-06-25

schorsch_76,
I'm following the instructions on the Raspberry pi forum.
I've just found that there is a gotcha or two with the serial console too.
Serial was ever thus :) It may not matter in 64 bit mode though.
As I say, I've only built stuff so far. I've not actually tested anything yet. _________________ Regards,

I git now the 64 bit kernel booting following the mentioned thread in the raspberry forum. But it still panics because of no userland Now i try to setup the buildroot image with an gcc in it. Video and audio is not yet working. All over serial line

schorsch_76,
Well done. I only get as far as Code: | U-Boot> fatload mmc 0:1 0x100 bcm2837-rpi-3-b.dtb
reading bcm2837-rpi-3-b.dtb
5126 bytes read in 42 ms (119.1 KiB/s)
U-Boot> fatload mmc 0:1 0x2000000 image
reading image
8786944 bytes read in 2496 ms (3.4 MiB/s)
U-Boot> booti 0x2000000
Starting kernel ... | Then nothing.
I guess the kernel doesn't go to 0x2000000 or is not self relocating.
It didn't help that I mounted the SD card as -t msdos, rather than -t vfat. My bcm2837-rpi-3-b.dtb vanished so I was using the wrong file.
How do you get to use Do you pack your kernel and dts files together with mkimage?
What command do you use.
Its encouraging that we both have the same size files. _________________ Regards,

In fact it is nearly default: I packed this into the uboot auto start.
Code: | fatload mmc 0:1 $fdt_addr_r bcm2837-rpi-3-b.dtb
fatload mmc 0:1 $loadaddr image
booti $loadaddr - $fdt_addr_r |
You can enter these commands into the uboot to start the image. Important is afaik also the cmdline.txt
Code: | cat p1/config.txt

kernel=u-boot.bin
kernel_old=1

The explanation is more useful i think, but i leave the listing abouve for completeness:
I added in the u boot console

Very important are the ' !
Now after you plug it in again, it reads uboot.env and after 2 sec it loads the dts and the image and boots it
Now the kernel command line is no longer read from the cmdline.txt but provided now via u-boot. I dont know yet how to read the cmdline.txt via u boot and pass it as bootargs. But i guess it is possible _________________ // valid again: I forgot about the git access. Now 1.2GB big. Start: 2015-06-25

schorsch_76,
I had console=tty1 in my cmdline.txt but everything else was correct, including the serial port set up.
I also had too many zeros in the kernel load address.
The other difference is I get
Code: | ** Unable to read "uboot.env" from mmc0:1 **
Using default environment |
How do you get one of those.
Hmm I guess that cmdline.txt is not used with u-boot, so I'm booting with a blank command line. _________________ Regards,

That looks like it was the problem. I had a console using black text on a black background :)
I've messed up something because I get a well known panic now.
Code: | VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2): error -19
Please append a correct "root=" boot option; here are the available partitions:
b300 62367744 mmcblk0 driver: mmcblk
b301 65536 mmcblk0p1 00000000-01
b302 10485760 mmcblk0p2 00000000-02
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) |
Its much easier with the uboot.env file. Mine is still wrong but it picked up the bootargs this time.
Thanks for your help. Its midnight here. With the change to DST thin weekend, I have to be up early.
More tomorow.
I have some userspace stuff but its missing gcc. _________________ Regards,

schorsch_76,
I can't get past the login prompt with my userland but adding init=/bin/bash to bootargs gets me a shell, so I'm "in", sortof.
Anyway, I can poke around from the inside now. _________________ Regards,

I had a similar issue as i tried the debian aarch64 userland. pam failed. So i switched to buildroot. I tried the usual /etc/shadow thingie (wiki raspberry pi) but it didnt work.
Is your userland gentoo?
How about using your gentoo userland and my "cross gcc" to emerge the gcc? _________________ // valid again: I forgot about the git access. Now 1.2GB big. Start: 2015-06-25

schorsch_76,
I don't have pam at all. The make.conf that comes free with crossdev has
USE=-pam set.
My part of a userland was obtained by using crossdev to build a aarch64-armv8a-linux-gnueabi cross toolchain then blindly using it to build @system in an empty target root.
Actually in /usr/aarch64-armv8a-linux-gnueabi/. Since I've not done anything special, except keyword a few packages, its done fairly well.
Maybe setting the profile to Code: | make.profile ->/usr/portage/profiles/default/linux/arm64/13.0/desktop | was a bit
aggressive when I didn't even have a @system set. That is not the cause of build issues though.
You will find Pi3_64_bit_root.tbz2 and Pi3_64_bit_boot.tbz2 at http://grytpype-thynne.org/~roy/Pi3_64bit/
They are the partition2 (ext4) and partition1 (vfat) copied from my SDCard.
The root password is raspberry but it doesn't work.
To poke about, append init=/bin/bash to bootargs and press return when
it looks like its died.
That's just you, bash and the kernel with a read only root.
Before you run emerge natively in arm64 you need to fix make.conf. Its still as it was for cross compiling.
It doesn't always give the login prompt. When it does, it doesn't always echo the username.
It never echos the password, nor gives any indication the the enter character at the end of the password was accepted.
Have fun.
**** edit ****
Login fix ....
edit /etc/inittab
Fix this line
Code: | # SERIAL CONSOLES
s0:12345:respawn:/sbin/agetty -L 115200 ttyAMA0 vt100 | Change vt320 to reah vt100
Comment this line
Code: | # Architecture specific features
#f0:12345:respawn:/sbin/agetty 9600 ttyAMA0 vt100 |
Notice that it will cause a race condition as it resets the console baud rate. _________________ Regards,

schorsch_76,
I have a working cross gcc and cross c++ and all the other good things built using crossdev.
They all seem to work.
Those programs run on an amd64 and produce code for aarch64-armv8a-linux-gnueabi using the files in /usr/aarch64-armv8a-linux-gnueabi/etc/portage.
This is all normal Gentoo but with the cross compiler twist.
I see how your script builds you a cross tool chain that ends up in Code: | INSTALL_PATH=/opt/cross |
I don't follow your schorsch_76 wrote: | I copied the /opt/cross folder to the SD card and added /opt/cross/bin to the PATH. |
because the code there is to run on your build host, not the armv8 target.
How did you use those tools to get a native armv8 gcc?
My attempt to use the cross toolchain to cross compile gcc itself ends with
Code: | /usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../libdecnumber/libdecnumber.a(decNumber.o): Relocations in generic ELF (EM: 183)
../libdecnumber/libdecnumber.a: error adding symbols: File in wrong format | so its using the wrong linker.
I tried the USB ports. Surprise suprise .. they don't work. :) _________________ Regards,

The script i posted a few das ago needs a cross compiler from cross dev (host: amd64 target: aarch64). In fact, This script cross compiles a compiler for the target that it can natively compile "Cross compiling a native compiler"
The "--host" in the configure steps specifies that host the target will run. See my /opt/cross/bin/gcc
In fact, i set /"opt/cross" owned by my regular user to make sure the aarch64 dont get mixed up with my other cross compiler in /usr. So i compiled the "/opt/cross" as normal user and installed it as normal user. It only runs on aarch64 not on my amd64 host. I havemt known about sysroot .. though .... /opt/cross later copied to the RPi3
Code: | hammerhead opt # file /opt/cross/bin/gcc
/opt/cross/bin/gcc: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, not stripped

schorsch_76,
After some 'faffing' about, I have the portage tree, the sources for gcc and your native armv8 gcc on my Pi.
If I can get emerge to use your gcc, my plan is to Code: | emerge gcc --nodeps -1 |
select the resulting gcc. Then run Code: | /usr/portage/scripts/bootstrap.sh |
which is the stage1 install.
Of course, none of the I/O works except the serial console, so it will be a sneakernet install.
I don't fancy PPP over a serial link at 115200 bits/sec. Nor kermit or [xyz]modem for file transfer.
That would almost be back to baseband modem speeds.
Progress so far ...
Code: | root@Pi_3 64_bit ~ # emerge gcc --nodeps -av1

This is the wrong package to practice on. If it doesn't find gcc, its going to unpack in all again at the next attempt. _________________ Regards,

Yes, i put the distfiles to the sdcard like you. That emerge grabbed my new gcc i exported "CC=/opt/cross/bin/gcc" Flex/Bison/m4 were compiled by this gcc and they work.
The unpacking stage took for me about 20 to 30 min. At the configure stage it failed at a type check for int64_t ...
So i tried yesterday various Versions of gcc and libs to "cross compile the compiler" but they all failed at the libstdc++3 stage at "vnsprintf" (dont habe the error currently here). I am up to fill a bug report on gcc.gnu.org/bugzilla.
The check for int64_t on the target is strange too ... that this fails .... _________________ // valid again: I forgot about the git access. Now 1.2GB big. Start: 2015-06-25

I tried:
- "amd64 to aarch64 Compiler 5.3.0" aarch64-linux-gnu triplet and aarch64-armv8a-linux-gnueabi. Both fail at the exact same line.
- "aarch64 to aarch64" compilers 5.3.0 and 4.9.3 failed at the same function (post above copied from the minicom) _________________ // valid again: I forgot about the git access. Now 1.2GB big. Start: 2015-06-25
