upgrade daisy -> jethro

Hi,

we have a customized board with Texas Instruments AM335x Processor. It's
based on Beaglebone Black and EVM Starter Kit.

We have a working yocto-daisy image running U-Boot 2013.07 and Kernel 3.14.
No we want to upgrade to jethro, including U-Boot 2015.07 and Kernel 4.1.

What I did:
- Merging U-Boot Patches from 2013.07 to 2015.07.
  The board boots and ping to other machine is possible from U-Boot command
line.

- Building Kernel 4.1 with defconfig from Kernel 3.14
  This Kernel boots, but no network interfaces come up. *ip a* only shows
loopback interface. Device Tree files are the same as in Kernel 3.14

- Building Kernel 4.1 with omap2plus_defconfig
  This Kernel doesn't boot, it hangs after U-Boot procedure.

My Questions:
- Anybody here who did something similar? Any hint how to handle yocto
upgrades in general?
- Are there any changes in device tree from kernel 3.14 to 4.1?
- How can I check if the problem is u-boot specific (Hardware init), device
tree or kernel driver?
- Anybody here who has a running linux kernel 4.1 for beaglebone black?

And, more general:
- How do you handle yocto source upgrades in your products / systems? Code
freeze after development?

Thanks in advance and best regards
Ruben

Why don't you get a beagle bone black and retry there?

Like this it would be easier to help, since we don't have your custom board.

I use a 4.4.x kernel with the mainline device tree am335x-boneblack.dtb
which works as well for a 4.1.x kernel.

Robert
