From 26cb167a5ca7e11385526fc4e2c67170e1aabedc Mon Sep 17 00:00:00 2001 From: Chris Blake Date: Fri, 1 Mar 2019 20:03:32 -0600 Subject: [PATCH] mpc85xx: Fix Aerohive HiveAP-330 initramfs image At some point our initramfs image grew over 6MB, which is causing an issue when uncompressing in the stock bootloader: => bootm 0x5000000 - 0x1000000; Image Name: Linux-4.19.24 Created: 2019-02-23 1:58:20 UTC Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6752470 Bytes = 6.4 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Booting using the fdt blob at 0x1000000 Uncompressing Kernel Image ... Error: inflate() returned -5 GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover Loading Device Tree to 00ffa000, end 00fffc78 ... OK To get around this, we need to move to an uncompressed image for the initramfs image. While this makes a larger image, it is thankfully bootable so people can then convert their devices to run OpenWRT. It's worth noting the non-initramfs image is under 3M, so it will be ages before we have any issues with the flashed kernel.
