From 834bd864245293d26bc9ca1ee956799de5865b37 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sun, 30 Dec 2018 20:38:15 +0100 Subject: [PATCH] apm821xx: switch MX60(W)'s recovery images to multi-image method In the past, the MX60(W)'s recovery images always had problems with the size restriction and never really worked without manual intervention. This patch reworks the initramfs, which allows the device to ease up on the impossible tight kernel size requirements for the initramfs image. This new initramfs can be loaded through the MX60(W) U-boot in the following way: => setenv bootargs console=ttyS0,$baudrate => tftpboot $meraki_loadaddr meraki_mx60-initramfs-kernel.bin [...] Load address: 0x800000 Loading: ################################################ [...] done [...] => bootm $fileaddr \## Booting kernel from Legacy Image at 00800000 ... ...
