I need help enabling and disabling these following respectively on Kernel level on Ubuntu 18.04, which gives us a base image of Ubuntu
Bootloader:
- Disable Dhcp as bootable source
- Disable Nvme0 as bootable source
- Disable Pxe as bootable source
- Disable Usb0 as bootable source
- Enable Mmc0 as bootable source
- Enable Mmc1 as bootable source
I see the following post in the documentation but dint get how go about it
Contains a space-delimited list of storage devices or network protocols that U-Boot scans to find boot scripts.
Valid values include:
•mmc0: the built-in eMMC
•mmc1: the SD card slot
•usb0: any attached USB Mass Storage device
•nvme0: any attached NVMe device
•pxe: network, using DHCP to receive an IP address, then PXE to download a syslinux configuration file
•dhcp: network using DHCP to receive an IP address, then TFTP to download a U-Boot boot script
This variable can specify a subset of the possible values, and even to a single value if the application does not require alternative boot devices.
