I need to recompile my current Beaglebone Black Linux kernel (4.4.91) to set CONFIG_STRICT_DEVMEM=n. This will allow the use of mmap to access the SPI interface hardware directly, among other things.
So far... I have loaded the latest version of arm-linux-gnueabihf gcc. Cloned the latest kernel source (https://github.com/beagleboard/linux/git) which is currently 4.4.91. Modified the kernel config options to set CONFIG_STRICT_DEVMEM=n. Compiled the kernel. Cloned, patched, and compiled u-boot. At this point the instructions that I have been following diverge and are more concerned with creating a bootable image on the SD card for testing or for replacing the entire contents of the eMMC on the Beaglebone. What I want to do is replace the existing kernel on eMMC with minimal impact to the current configuration. My current filesystem is BeagleBoard.org Debian Image 2016-05-13. Can someone explain the process to replace the kernel on eMMC? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
