From 5a3b1e5b5765208990e45c852c0412f210d63594 Mon Sep 17 00:00:00 2001 From: Tad Davanzo Date: Fri, 5 Feb 2021 22:42:47 -0500 Subject: mvebu: venom resize kernel to 6MB venom has a 3MB kernel partition as specified by the DTS. 3MB is not sufficient for building with many kernel modules or newer kernel versions. venom uboot however as set from factory will load up to 6MB. This can be observed by looking a uboot log: NAND read: device 0 offset 0x900000, size 0x600000 6291456 bytes read: OK and from uboot environment variables: $ fw_printenv | grep "priKernSize"; priKernSize=0x0600000 Resize the root partitions from 120MB to 117MB to let kernel expand into it another 3MB. And set kernel target size to 6MB. Lastly set the kernel-size-migration compatibility version on venom to prevent sysupgrading without first reinstalling from a factory image.
