[Buildroot] BB-Black setup fails to boot using Buildroot Training Lab Book [December 26, 2016]

[Ashish_Kumar_Mishra]

Hi All ,

This in my first post here & i am not sure weather such support / problem
queries are allowed here or not. 
Would request to please let me know the correct forum so that i can continue
there. 

This is my first attempt to learn the Buildroot (and BB Black) . 

I am following the procedure mentioned in Buildroot Training Lab Book from
free electrons dated December 26, 2016. 
After following all the steps i created an SD card setup but the board
booting fails with below mentioned log:-

U-Boot SPL 2016.03 (Dec 27 2016 - 12:45:34)
Trying to boot from MMC
Card doesn't support part_switch
MMC partition switch failed
*** Warning - MMC partition switch failed, using default environment

reading u-boot.img
reading u-boot.img


U-Boot 2016.03 (Dec 27 2016 - 12:45:34 +0530)

       Watchdog enabled
I2C:   ready
DRAM:  512 MiB
MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1
Net:   Could not get PHY for cpsw: addr 0
cpsw, usb_ether
Press SPACE to abort autoboot in 1 seconds
reading uImage-dtb.am335x-boneblack
** Unable to read file uImage-dtb.am335x-boneblack **
Wrong Image Format for bootm command
ERROR: can't get kernel image!
=> 


Could group members please provide few pointers to get the proper board
booting  .

Thanks 
Ashish Kumar Mishra.

I suspect you forgot to put the uEnv.txt file on the SD card. Please
read again the "Flash the system" section of the "Basic Buildroot
usage" lab.

Best regards,

Thomas

Dear Thomas Sir , 
Thanks for replying. 

I had uEnv.txt in the boot partition in the /boot directory. 
Attached is the snap of the contents (just in case if required) .

Hi Sir / All , 

The created setup *works properly on BeagleBone "A6"* but same sd card fails
to boot with BeagleBone "A6A" .
Will check the behaviour on Beaglebone "C" & share . 

I am not much clear as what effects the same image to behave differently on
two different version. 

Will update the thread as in case some additional info .

Thanks 
Ashish Kumar Mishra.
