Hi all,
I'm having difficulties booting my kernel. I've checked the followings:
1. CONFIG_CMDLINE_TAG, CONFIG_SETUP_MEMORY_TAGS and CONFIG_INITRD_TAG all enabled. (#define as 1 in my include/configs/myboard.h file)
2. the machines descriptor in my board specific file under linux/arch/arm/myboard.c as follows:
MACHINE_START(LP2A, "SOCLE-LP2A")
MAINTAINER("Socle Ltd/DE1")
BOOT_MEM(0x40000000, 0x1e800000,0x9e800000)
BOOT_PARAMS(0x40000100)
FIXUP(fixup_lp2a)
MAPIO(lp2a_map_io)
INITIRQ(lp2a_init_irq)
MACHINE_END
Few notes:
* Kernel version is 2.4.21.rmk2 and was obtained from www.kernel.org http://www.kernel.org/ , cross compiler tool was from www.gnuarm.com http://www.gnuarm.com/ - version 3.4.3.
* It seems that misc.c does the decompression of the kernel again, when kernel is already decompressed by u-boot to the load address 0x40008000.
* Do I have to modify head.S at all?
I am pretty sure that I've done pretty much everything u-boot needs to boot my kernel but it just won't do it (attached below is the log of the output from the board). Can anyone help please? Thanks in advance!
Andy
