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: root@beaglebone:/opt/scripts/tools# ./version.sh git:*/opt/scripts/*:[e066cb50c5eda24ce09227b1a155da823d56225a] eeprom:[A335BNLTBWA51646BBWG0358] dogtag:[BeagleBoard.org Debian Image 2017-02-12] bootloader:[/dev/mmcblk0]:[U-Boot 2017.03-rc1-00003-ga09f2d] bootloader:[/dev/mmcblk1]:[U-Boot 2016.11-rc3-00002-g73df7f] kernel:[4.4.48-ti-r88] nodejs:[v4.7.3] root@beaglebone:/opt/scripts/tools# df Filesystem 1K-blocks Used Available Use% Mounted on udev 10240 0 10240 0% /dev tmpfs 99956 3036 96920 4% /run /dev/mmcblk0p1 7376168 2934944 4090164 42% / tmpfs 249884 4 249880 1% /dev/shm tmpfs 5120 4 5116 1% /run/lock tmpfs 249884 0 249884 0% /sys/fs/cgroup tmpfs 49980 0 49980 0% /run/user/1000 root@beaglebone:/opt/scripts/tools# fdisk -l /dev/mmcblk0 Disk /dev/mmcblk0: 7.2 GiB, 7744782336 bytes, 15126528 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xc9171f1a Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 * 8192 15126527 15118336 7.2G 83 Linux I HAVE NOT RUN mkfs. ???? 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.

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