Title:
Kernel cmdline limited to 256 characters in pxeboot
Status in Linaro U-Boot:
New
Status in “u-boot-linaro” package in Ubuntu:
New
Bug description:
The default # of characters allowed in the omap4 kernel is set at 512
according to /usr/src/linux-headers-3.0.0-1200-omap4/include/asm-
generic/setup.h, however u-boot only allows 256 on the append line in
the pxe config. With the panda, this is severely limiting due to the
need to work around a known memory hole with mem=456M@0x80000000
mem=512M@0xA0000000. Either the memory hole is left unmasked, which
may cause random kernel oops during an image install, or netinstall
cannot effectively be preseeded for full automation.
Working length:
append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc
debian-installer/framebuffer=false console=ttyO2,115200n8
url=http://master.gruenet/preseed/preseed.cfg locale=en_US
setup/layoutcode=en_US console-setup/layoutcode=en_US auto netcfg/get_hostname=
Failing length:
append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc quiet
debian-installer/framebuffer=false console=ttyO2,115200n8
url=http://master.gruenet/preseed/preseed.cfg locale=en_US
setup/layoutcode=en_US console-setup/layoutcode=en_US auto netcfg/get_hostname=
Difference is the addition of "quiet" to reduce the noise level of
kernel boot messages.
