capemgr_loader causes kernel panic in 4.1.18-bone-rt-r20

QuickJack commented 8 years ago

I am trying to load capes using uEnv.txt. The BB-BONE-LOGIBONE cape is based on this https://github.com/QuickJack/logi-kernel/blob/master/beaglebone-black/logibone_ra2/BB-BONE-LOGIBONE-00A3.dts. I am using am33xx-boneblack-oberlay.dtb.

(1) cape_enable=bone_capemgr.enable_partno=BB-BONE-LOGIBONE:00A3 => Both capes are loading/working fine (2) cape_enable=BB-UART1,bone_capemgr.enable_partno=BB-BONE-LOGIBONE:00A3 => Both capes are loading/working fine (3) cape_enable=BB-UART1,BB-UART2 and loading BB-BONE-LOGIBONE by using "echo BB-BONE-LOGIBONE:00A3 > /sys/devices/platform/bone_capemgr/slots" is working fine (4) cape_enable=BB-UART1,BB-UART2,bone_capemgr.enable_partno=BB-BONE-LOGIBONE:00A3 => kernel panic:

QuickJack commented 8 years ago

Ich have to say, that I am not using the EEPROM on the Logibone. It has never been programmed. I am loading everything manually.

QuickJack commented 8 years ago

It is enough to add "cape_enable=bone_capemgr.enable_partno=UART1,UART2,UART3" to uEnv.txt. This will produce the above kernel panic. There's also an excessive delay when the capes are initialized during boot.

This bug is not related to the Logibone in any way!

I don't see that oom issue yet:

QuickJack commented 8 years ago

You are using a different kernel. Did you also use am335x-boneblack-overlay.dtb in uEnv.txt?

I will post the exact output when using UART1, UART2 & UART3 on monday.

RobertCNelson commented 8 years ago

it's the exact same overlay patchset, no i used: am335x-bonegreen-overlay.dtb

But that's exactly the same as am335x-boneblack-overlay.dtb

QuickJack commented 8 years ago

There's on difference. I have connected the Logibone and did not program the EEPROM which is at address 0x57. According to http://papermint-designs.com/community/node/331 this is equivalent to Slot 3.

The relevant dmesg output is:

[    4.340147] bone_capemgr bone_capemgr: Invalid signature 'ffffffff' at slot 3
[    4.347345] bone_capemgr bone_capemgr: slot #3: No cape found

QuickJack commented 8 years ago

I checked it with a blank BeagleBone Black and the problem is still there. It might have something to do with the fact, that I cannot update the overlays from https://github.com/RobertCNelson/bb.org-overlays using install.sh. The problem is "E: Unable to locate package bb-customizations". Obviously this package does not exisit in my active repositories. What exactly is the purpose of this package?

I manually did all the steps defined in install.sh except installing bb-cusomizations. However, the problem still exists. Here is my full bootlog:

Yeah i can factor out bb-customizations, that's just to bring the initramfs hook, dtbo..

Not sure if # is ignored, but the dtb= should be removed..

Using "console=ttyS0,115200 bone_capemgr.enable_partno=BB-UART1,BB-UART2,BB-UART3 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait dtb=am335x-boneblack-overlay.dtb" the problem still exists.

Yes, I changed uEnv.txt. I added:

fdtfile=am335x-boneblack-overlay.dtb
dtb=am335x-boneblack-overlay.dtb

Is this https://eewiki.net/display/linuxonarm/BeagleBone+Black information about uEnv.txt still up to date?

RobertCNelson commented 8 years ago

It is, but you don't need to pass "dtb=am335x-boneblack-overlay.dtb" on the boot arg's.. just set it in /boot/uEnv.txt as:

dtb=am335x-boneblack-overlay.dtb

Regards,

@QuickJack still no oom's..

QuickJack commented 8 years ago

I did not change my kernel config. Here is the link to the pastebin of my kernel config: http://pastebin.com/MErh66xA (zcat /proc/config.gz)

I have a feeling that it has something to do with UBoot and/or uEnv.txt. I did not download an up to date image. I started a long time ago using an Ubuntu image and a 3.8.13 kernel. I have recently started to upgrade my kernel to 4.1.x. So I am NOT using the new partioning layout.

QuickJack commented 8 years ago

I tested https://rcn-ee.com/rootfs/2016-02-11/microsd/bone-ubuntu-14.04.3-console-armhf-2016-02-11-2gb.img.xz which uses the TI kernel by default. It indeed works to activate UART1, UART2 & UART3. However, I noticed that a lot of things have changed:

(1) There are 2 different uEnv.txt files: /uEnv.txt and /boot/uEnv.txt (2) After running install_kernel.sh from the bb-kernel the system won't boot. Those two kernel variants are obviously incompatible in some way. (3) There is only one partition. The boot partion seems to be removed (4) I cannot find UBboot. During boot a 2013 version of UBoot is loaded. I guess this is loaded from the eMMC. I cannot use the eMMC because it shares the GPMC pins. (5) I used to load the kernel image from /boot/zImage. The new SDCard uses /boot/vmlinuz-

I think there's a lot of confusion about which UBoot image is loaded from which location. Also the format of uEnv.txt is constantly changing. There are even multiple different versions of uEnv.txt within a single partition.

RobertCNelson commented 8 years ago

(1) There are 2 different uEnv.txt files: /uEnv.txt and /boot/uEnv.txt

"/uEnv.txt" is just a shim for old versions of u-boot stuck in eMMC (retains compatibly all the way back to, Angstrom's 2013.06.20)

Since you are utilizing the eMMC for something else, just zero out the eMMC so you don't have to deal with that version of u-boot..

(2) After running install_kernel.sh from the bb-kernel the system won't boot. Those two kernel variants are obviously incompatible in some way.

Remove "/uEnv.txt" then "install_kernel.sh" will work, as it's falling in the first if statement here: https://github.com/RobertCNelson/stable-kernel/blob/master/tools/install_kernel.sh#L146-L166

when it really needs to enter the 2nd, if..

(3) There is only one partition. The boot partion seems to be removed
(4) I cannot find UBboot. During boot a 2013 version of UBoot is loaded. I guess this is loaded from the eMMC. I cannot use the eMMC because it shares the GPMC pins.

Correct, it makes things a lot more reliable, MLO/u-boot.img are dd'ed into the 1MB hole at the start of the drive https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard

(5) I used to load the kernel image from /boot/zImage. The new SDCard uses /boot/vmlinuz-

I think there's a lot of confusion about which UBoot image is loaded from which location. Also the format of uEnv.txt is constantly changing. There are even multiple different versions of uEnv.txt within a single partition.

Here is the full right up of what's going on:

http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0

Haven't really made any changes to ^ since summer of 2014, just tweak/fix/addon's, but the same syntax in /boot/uEnv.txt

QuickJack commented 8 years ago

Many thanks for your comments. I will take a look into it asap.

I manually added the kernel to the new SDCard by moving the zImage to /boot/vmlinuz-4.1.18-bone-rt-r20 and adding the dtb files to /boot/dtbs/4.1.18-bone-rt-r20. I commented out the loadxrd line in /uEnv.txt. I also uncommented the dtb=am335x-boneblack-overly line and activated the UARTs in /boot/uEnv.txt. Here is my bootlog:

After all these tests I think that the problem seems to be kernel related

RobertCNelson commented 8 years ago

Oh, there is one other thing we should test. ;) Hold the boot button, before power up, to force the much newer version of u-boot on the microSD to load vs, the old version in eMMC...

Regards,

If I do understand you right, then u-boot.img and MLO are written to a fixed location within the SDCard outside of any filesystem. Wow, this sounds like magic...

QuickJack commented 8 years ago

I did another test which proves that the bb-kernel has a problem. I copied /boot/vmlinuz-4.1.17-ti-rt-r47 from the above mentioned image to my SDCard to /boot/uboot/zImage. In order to save some time I did not update .dtb files or modules. The system boots fine.

After activating UARTs 1..3 there is no problem at all:

Can you reproduce the problem with capemgr?

I have tested 4.1.18-ti-rt-r52.1 which uses the Linux DMA Engine API. After recompiling the Logibone driver it is working fine. Unfortunately, the CPU load increased from 17% to 23% when running my application. This means that this kernel is a step back compared to the bb-kernel.

QuickJack commented 8 years ago

Meanwhile I have switched to the latest rootfs and the problem disappeared. I am using a 4.1.x bone-rt kernel. There seems to be a problem with my old rootfs and/or partitioning scheme. It does not play nicely with capemgr.

I am closing this issue as it involves a combination of a new kernel and an old rootfs/ partitioning scheme which is difficult to reproduce.
