Initially load capes on AM335x without EEPROM

Hi,

I’m currently working on a custom BeagleBone Black of ours and I have a few problem. The electronic is the same except that there is no graphic chip and no EEPROM.

I’m booting on a µSD card the Angstrom distribution used in the BBB. The board is working well except that I have the following message during the boot “[ 5.561536] bone-capemgr bone_capemgr.9: Failed to scan baseboard eeprom”.

This is perfectly normal because I have no EEPROM. My problem is that I didn’t know that the EEPROM was mandatory to initialize the cape manager. Thus, my EMMC is not loaded by the OS.

I already tried to enable the cape with the uEnv.txt but it did nothing.
I also tried to load it manually but in my cape manager folder there is no “slot” file so i guess that the cape manager is simply OFF.

Is there a way to bypass the EEPROM and to load by default the EMMC cape ?
I’m actually going through the kernel compilation, i’m afraid that I can’t avoid it.
Does someone have any experience on this ?

Thank you by advance,

Julien

Mainline kernel has the eMMC setup by default in the dts...

Since you didn't specify a need for v3.8.x/capemgr, it's a viable option. :wink:

Hi Roberts,

Thank you this is great news. The reason why I didn't go with kernel version
over 3.8.x is because the u-boot that I tried didn't include a default load
device tree.

So now, I'm trying to use the eMMC Flasher from this link :
http://elinux.org/BeagleBoardUbuntu#eMMC:_BeagleBone_Black

I have a few problems with the MLO and the u-boot since I have no EEPROM.
I used the old MLO which agrees that I'm using a BBB by default. But I'm
still blocked on the u-boot part.

I tried using the uEnv.txt file with the following args but it is not
working:
board_name=A335BNLT
fdtfile=am335x-boneblack.dtb
uenvcmd=run loadimage; run loadfdt; run mmcargs; bootz ${loadaddr} -
${fdtaddr}
fdtdir=/boot/dtbs/3.8.13-bone59

My main problems are the following:
** Unable to read file /zImage **
** Unable to read file /boot/dtbs/3.8.13-bone59/am335x-boneblack.dtb **
Bad Linux ARM zImage magic!

Do you know how I could solve this ?

Best regards,

Julien

Hi Roberts,

Thank you this is great news. The reason why I didn't go with kernel version
over 3.8.x is because the u-boot that I tried didn't include a default load
device tree.

As long as your clone has the same memory and is 1Ghz version of the
am335x, you can use this u-boot patch:

https://github.com/RobertCNelson/Bootloader-Builder/blob/master/patches/v2014.07/0002-NFM-Production-eeprom-assume-device-is-BeagleBone-Bl.patch

Hi Robert,

Thank you, it's a good news.

The main reason I stayed on the 3.8 kernel version is because I wanted to
use the same kernel that was in the BBB. But it appears that the work you
made on the capemgr will be of help for my custom board.

However, now I have another problem.
I'm trying unsuccessfuly to use this flasher:
http://elinux.org/BeagleBoardUbuntu#eMMC:_BeagleBone_Black

The problem is that the u-boot and the MLO doesn't have a default dtb. And
since I don't have a EEPROM, the boot is stuck.

I tried to use the MLO from the BBB, which seems to be OK. And now I'm
trying to use the uEnv.txt file to pass the BBB arguments to the u-boot but
I still can't boot properly.

The error that I can't resolve is essentially:
Bad Linux ARM zImage magic!

This just means you are trying to load something that isn't what it expects..

pastebin.com your serial boot log..

I know that the EEPROM should contain this:
struct am335x_baseboard_id {
        unsigned int magic;
        char name[HDR_NAME_LEN];
        char version[4];
        char serial[12];
        char config[32];
        char mac_addr[HDR_NO_OF_MAC_ADDR][HDR_ETH_ALEN];
};

Does this problem have something to do with the magic argument ?

Nope..

Is it eady to resolv ?

As long as your clone has the same memory and is 1Ghz version of the
am335x, you can use this u-boot patch:

https://github.com/RobertCNelson/Bootloader-Builder/blob/master/patches/v2014.07/0002-NFM-Production-eeprom-assume-device-is-BeagleBone-Bl.patch

Regards,

Yes, my custom board has the same RAM and µP. Only the eMMC is a 32GB one but I think that this will not be a problem.

I’ll try to apply the patch to the u-boot.

Thank you !!!

Hi Robert,

I tried to use the u-boot patch you mentionned but I still can’t see the eMMC cape.

I’m using the current ubuntu image : bone-ubuntu-14.04-console-armhf-2014-07-06-2gb

Here is my dmesg result. Do you see where the problem come from ?

Best regards,
Julien

Hi Robert,

I tried to use the patch for the u-boot you mentionned but I have no results
with it.

I still have the same problem, my eMMC is not detected because the eMMC cape
is not loaded. I'm currently working with the following image on a µSD card,
bone-ubuntu-14.04-console-armhf-2014-07-06-2gb , and a BBB which from I
retrieved the EEPROM.

Here is the pastebin link of my dmesg: http://pastebin.com/NPWtJhdz
Here is the pastebin link of my serial startup: http://pastebin.com/Mk8DgjnZ

Do you have any idea of why it is not loading ?
Will I need to modify and recompile the kernel ?

u-boot looks perfect to me.. It loaded everything exactly like a real
"BeagleBone Black"..

Next "you" just need to patch the kernel to bypass the eeprom = valid,
capemgr check.

Regards,

OK.

So I took the sources from your git repository and I'm trying to force the
capemgr to load the emmc. I'm trying to modify the patch.sh file to force
it.

Do you know if there is an easiest way to do it ?
I'm sorry, I'm a beginner concerning kernel things.
The kernel compilation takes quite some time, it will save me a lot of time
if you could give me a hint.

Best regards,
Julien

Forget it, it's ok.
Actually I took the 3.16 kernel.
I just have a few things to fix during the kernel compilation (no LCD, default
cpu-freq at 800MHz...) and it will be perfect.

Thanks a lot for your advices.

which lcd?

Regards,

I went with the 3.15.9 kernel which has not included the cape for lcd so
it's ok.

However, I have a lot of trouble with the g_multi module that I tried
unsuccessfuly to configure during the kernel building.

I'd like to use the usb0 as the beaglebone does: RNDIS ethernet and mass
storage. I checked the option to build a module configured by file and when
asked I chose the mass storage and RNDIS drivers but I can't find the
g_multi module in the kernel. Furthermore, it is not loaded by the OS at
startup.

Also, I can't connect by ssh via the ethernet port but it seems to be
configured well:

Do you have ideas on these problems ?

Hello Julien,

I am working on similar project (custom BBB board). I have tested my system on the BB board and i am ready to move to the PCB design (same uP & RAM etc… but not EEPROM). This post had given me some insight on what problems to expect.
My question is unrelated to the discussion on this thread, but I am afraid that when I move to the PCB design stage it will be very trick. So could you please recommend a PCB/schematics designing service along with PCB fabrication and assembly that could get my custom BBB done?

Thanks in advance.

Regards,
Khalid
