BBBW testing

Progress:
The error I struck using grow_partition.sh was:

Re-reading the partition table …
sfdisk: BLKRRPART: Device or resource busy
sfdisk: The command to re-read the partition table failed.
Run partprobe(8), kpartx(8) or reboot your system now,
before using mkfs
sfdisk: If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

I rebooted and ran:

So there is only one partition BUT it starts at 8192 sectors. Is there absolutely nothing pior to 8192 sectors? Is there a MRB in the first 512 bytes? If I used dd in linux must I allow for that? Why so many sectors (8192)? The version is: bootloader:[/dev/mmcblk0]:[U-Boot 2017.03-rc1-00003-ga09f2d] Is U-Boot 2017.03-rc1-00003 sufficiently up to date?

After so long faulty? After restart checked slots which was the same as above. In /boot/uEnv.txt I uncommented:disable_uboot_overlay_audio=1 In /boot/uEnv.txtadded cape_enable=bone_capemgr.enable_partno=BB-UART1,BB-I2C1,BB-UART4 I shutdown the BBBW but it rebooted.

BB-BONE-LCD7-01 uses some of AIN pins. AIN0 to AIN3?

The important result is that using uboot overlays does NOT impact on wireless. Regards, Kevin.
