Subject: [Buildroot] [PATCH 1/4] configs/amarula_vyasa_rk3288: adjust U-Boot config to boot larger kernel image
Date: Fri, 19 Apr 2019 15:27:15 +0530	[thread overview]
Message-ID: <20190419095718.8444-1-shyam.saini@amarulasolutions.com> (raw)

Default value of CONFIG_SYS_BOOTM_LEN in u-boot causes board reset for
large uImage files, so add u-boot patch to increase the maximum kernel
image size.

+The default value of CONFIG_SYS_BOOTM_LEN is 0x800000 i.e, 8MB which
+causes board reset because of larger uImage size.

+   Booting using the fdt blob at 0x1f00000
+   Loading Kernel Image ... Image too large: increase CONFIG_SYS_BOOTM_LEN
