Gilles Chanteperdrix answer :
Did you and compile u-boot with the CONFIG_SHOW_BOOT_PROGRESS option ?
Stephane Mallem :
Ok I use CONFIG_SHOW_BOOT_PROGRESS. U-boot is all right when I use bootm
But uClinux doesn't start.
U-Boot 1.1.1- fff (Feb 4 2005 - 17:31:42)
CPU: MOTOROLA MCF5272 (Mask:1)
Board: MOTOROLA MCF5272C3 EVB
DRAM: 16 MB
FLASH: 2 MB
--> bootm 0xfff00000
## Booting image at fff00000 ...
Image Type: M68K Linux Kernel Image (gzip compressed)
Data Size: 719611 Bytes = 702.7 kB
Load Address: 00020000
Entry Point: 00020000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
Starting kernel ...
I wait for ever something else appear on the screen.
So I look Uclinux code and use a scope in combination with port A to see
My conclusion is : printk() execute 3 time, but nothing appear on TXD.
Uclinux crashes somewhere in free_area_init_node() in pagint_init() in
setup_arch() in init_start_kernel()
I have no idea what's happened !
