boot failure on SparkFun blocks (base or console)

[ecc1]

I cloned https://github.com/andy-shev/linux and checked out the eds branch.
The tree is at e72aad722abd0a639a3ef4c42d8e59f4adc50d9e

On my desktop (Debian amd64, running stretch), I did:
$ make i386_defconfig
$ make ARCH=i386 -j4 bzImage
I copied bzImage to the /boot partition (/dev/mmcblk0p7) on my Edison.
I rebooted and entered U-Boot. I changed the bootargs as shown in the attached file and booted bzImage. Console output from the boot is attached, as is my kernel .config file.

Thanks for your time in looking at this.

The very latest i386 (eds branch) works for us. I have just compiled it and here is the paste log...wireless and external mmc should be working with patches from Andy...I am going to test them as well

Can you tell me which tree you're using (sha1 of HEAD) and post a copy
of your kernel .config? I'd like to try to reproduce your success
exactly.

Please use the following 7z file (please remove the pdf extension). Contains the Andy's patches + config.
i386-config-edison-mainline-with-p-andy.7z.pdf

Kindly just checkout the latest eds branch.....i will check sha1 later for you...

[ecc1]

I've now tried those patches, with your exact .config and with the (patched) i386_defconfig, with gcc-6 and gcc-5, and all still result in error messages like this:

I'm probably doing something stupid; would you mind pasting the commands you used to configure and compile the kernel?

[atlury]

Yes before that, can you please burn and test this release
https://github.com/atlury/Intel-Edison-OS-Images/releases/download/AlpineLinux-3.4.3-Mainline-Kernel/Alpine-Edison-Distro-Mainline-4.8-RC3.7z

1. Extract
2. run flashall.bat --recovery first and then plug in the board
3. immediately after that run flashall.bat (without disconnecting or re-plugging the board)

Meanwhile I will prep a guide for you.

To disable the watch dog timer please run a script something like
while [ 1 ] ; do sleep 1; echo V > /dev/watchdog; echo V > /dev/watchdog0; done

the login is root and no password

[ecc1]

I'd rather not reflash if I can avoid it but if I hit a complete brick wall I will. I notice a newer U-Boot in your boot log; is there anything that could be doing differently?

My system also disables watchdog in /etc/rc.local, but of course it's not getting that far with this kernel.

[ecc1]

This doesn't seem to be a valid 7z archive, according to 7-Zip (a) [64] 16.02 : https://github.com/atlury/Intel-Edison-OS-Images/releases/download/AlpineLinux-3.4.3-Mainline-Kernel/Alpine-Edison-Distro-Mainline-4.8-RC3.7z

[atlury]

Yes my apologies, I re-uploaded...please share you hangouts...i will help you compile...We use a customized version of u-boot suited for that particular rootfs....you can then share a tutorial here...

[ecc1]

I tried the kernel from your Alpine image and got the same errors. Finally I realized that all of these tests had been with my Edison module on a SparkFun base block. I moved the Edison module to an Intel mini-breakout board and it works fine.

I have no idea what difference the base board should make. Andy, please let me know if there's anything you'd like me to try to pinpoint and debug the difference in behavior.

Rahul, thanks very much for your time and patience.

[atlury]

Thats strange. Even i am using the following sparkfun boards only.

Base block with microsd card block.

[ecc1]

I have a Pi Block with an SPI device connected; I'll try disconnecting that to see if that's affecting the boot.

[ecc1]

So it also boots correctly on just the Sparkfun base block. But when also connected to a Sparkfun Pi Block, wired to an SPI device, it always produces the i2c and other errors in my original boot log.
