I have built and installed a new kernel (4.1.16-bone18) for BeagleBone Black, following this manual.
After the installation, with 'uname -a', the output is "... 4.1.16-bone18 ..." (new kernel), but as soon as a reboot is done, the previous kernel is reloaded. In this case, BBB returns to original kernel, "... 3.8.13-bone79 ...".
How is this possible? Is there any way to make this change permanent?
