Bug ID: 9091
Summary: U-Boot fails to boot with large ramdisk
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: michaellmonaghan at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
U-Boot fails to load a large ramdisk into memory properly (tested to occur with
a 20MB image on the zynq microzed). I have found a solution to the problem but
I'm unsure how to fix the problem in buildroot.
The U-Boot environment variable 'sdboot' is set to
echo Booting from SD...; run envload; run fpgaboot; fatload mmc 0 0x1000000
${kernel_image} && fatload mmc 0 0x2000000 ${ramdisk_image} && fatload mmc 0
0x3000000 ${devicetree_image} && bootm 0x1000000 0x2000000 0x3000000
I believe the device tree is being written on top of the ramdisk. The system
boots when 'sdboot' is set to
echo Booting from SD...; run envload; run fpgaboot; fatload mmc 0 0x1000000
${kernel_image} && fatload mmc 0 0x3000000 ${ramdisk_image} && fatload mmc 0
0x2000000 ${devicetree_image} && bootm 0x1000000 0x3000000 0x2000000
Here is a log of the default boot behavior.
