I've looked into this problem but I don't manage to get a hold on the magic behind the scenes. For instance grub.cfg is generated ok in the following locations: build/tmp/work/fri2_noemgd-poky-linux/core-image-minimal-1.0-r0/core-image-minimal-1.0/grub.cfg build/tmp/work/fri2_noemgd-poky-linux/core-image-minimal-1.0-r0/core-image-minimal-1.0/hddimg/EFI/BOOT/grub.cfg build/tmp/work/fri2_noemgd-poky-linux/core-image-minimal-1.0-r0/core-image-minimal-1.0/iso/EFI/BOOT/grub.cfg with something like # Automatically created by OE serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 default=boot timeout=10 menuentry 'boot'{ linux /vmlinuz LABEL=boot root=/dev/ram0 console=ttyPCH1,115200 console=tty0 video=vesafb vga=0x318 initrd /initrd } menuentry 'install'{ linux /vmlinuz LABEL=install root=/dev/ram0 console=ttyPCH1,115200 console=tty0 video=vesafb vga=0x318 initrd /initrd } However, I cant find /boot/grub/grub.cfg on the device - actually there is not /boot to look for. Can you shed some light on this matter, in particular to how grub.cfg is generated (and where) so that I can further trace this on my own. 22331 7 radu.moisan 2012-06-19 11:59:26 +0000 I've just took a second look on the device and the 40_custom is indeed missing the serial params, but grub.conf is still nowhere to be found, /boot has only the compressed and uncompressed kernel. Any hints would be very helpfull. 22425 8 dvhart 2012-06-20 15:36:47 +0000 I suggest reviewing the installation script to understand how grub is installed and then comparing that with the image you have on hand. 22454 9 dexuan.cui 2012-06-21 01:52:38 +0000 (In reply to comment #7) > I've just took a second look on the device and the 40_custom is indeed > missing the serial params, but grub.conf is still nowhere to be found, /boot > has only the compressed and uncompressed kernel. Any hints would be very > helpfull. Hi Radu, I think the original report "no serial output during boot after install" means the post-installation boot rather than the installation boot. I think Comment 6 only means the installation boot is OK. Did you try the post-installation boot? 22489 10 radu.moisan 2012-06-22 08:33:45 +0000 The post installation boot is missing the parameters. This is my target. 22502 11 radu.moisan 2012-06-22 14:34:27 +0000 Did this feature work in the past? From what I'm seing now, It looks much like it was never there, but again I might be missing something. What I'm tring to say is that install.sh (or init-install.sh as it appreas in poky repository) will set the __ROOTFS__, __VIDEO_MODE__ and __VGA_MODE__ in 40_custom file (grub init file) but I cannot see any trace of the console parameters SERIAL_CONSOLE (set in fri2.conf). So the scripts look to me like they are working fine, as intended. The paremeters added in fri2.conf, as I understand it, override the ia32-base.inc file. But further away, I cannot relate these two files with the above mentioned process. 22503 12 radu.moisan 2012-06-22 14:37:47 +0000 One small addition to my previous post. If I understood correctly 40_custom literaly becomes the grub.cfg file at install time. Please comment is otherwise. 22505 13 dvhart 2012-06-22 14:41:06 +0000 (In reply to comment #12) > One small addition to my previous post.

You have this right.SERIAL_CONSOLE (via APPEND I think) should be respected and treated in a similar way to __VIDEO_MODE__ and __VGA_MODE__. 22517 14 dexuan.cui 2012-06-24 08:42:09 +0000 (In reply to comment #11) > Did this feature work in the past?

However, when I tried to test the changed, I realised that console=ttyPCH1,115200 is not taking effect, even if introdiced manually in grub. Can anyone confirm this? 23216 17 dvhart 2012-07-18 14:43:58 +0000 (In reply to comment #16) > I have modified 40_custom, init-install.sh and init-live.sh so that they > process the "console=..." parameters as well.

How do you mean "it is not taking effect" ? Does it no appear in /proc/cmdline? Are you just unable to use the serial console? Are you testing on an FRI2? 23240 18 radu.moisan 2012-07-19 07:20:20 +0000 (In reply to comment #17) > How do you mean "it is not taking effect" ? Does it no appear in > /proc/cmdline? Are you just unable to use the serial console? Are you > testing on an FRI2? Yes I'm testing on FRI2. I have serial output in bios and in grub but nothing once the kernel kicks in. I used "console=ttyPCH1,11520" in grub as kernel boot option. The option is present in the output of "cat /proc/cmdline" once the kernel finished booting. 23241 19 radu.moisan 2012-07-19 07:22:03 +0000 (In reply to comment #18) > (In reply to comment #17) > > How do you mean "it is not taking effect" ?

At this point I'm adding this option manually just to exclude from the ecuation my patch. 23252 20 radu.moisan 2012-07-19 12:01:09 +0000 submitted a patch, waiting review for now. the problem with the serial device still applies. I've checked the kernel config and it seems fine, it may be a driver issue... anyway we should address this problem in a separate bug. 23257 21 dvhart 2012-07-19 14:27:18 +0000 (In reply to comment #18) > (In reply to comment #17) > > How do you mean "it is not taking effect" ?

The option is present in the output of "cat > /proc/cmdline" once the kernel finished booting. Is "console=ttyPCH1,11520" a typo? It should be "console=ttyPCH1,115200". 23258 22 dvhart 2012-07-19 14:28:24 +0000 (In reply to comment #20) > submitted a patch, waiting review for now. > the problem with the serial device still applies.

Which FRI2 revision are you using? 23304 23 radu.moisan 2012-07-20 06:34:31 +0000 I used "console=ttyPCH1,115200" manually added to grub kernel options and I had not output on serial console (in the context where grub was working fine on serial console). I am using Rev.1.0 However, my patch was accepted so now the options should be preserverd. If problems are found with the serial port in Rev.1.0 (or with the kernel for that matter) please submit another bug. 25813 24 alexandrux.palalau 2012-09-26 21:52:01 +0000 Verified under master branch commit ID 807ff46bc9d94106a11a58621994cc15e80f6d14.
