I'm coming back to the comunitee with good news , especially for me !-)
I succeed to start linux (2-4.26) from u-boot 1.1.4 on ML403.
When U-boot start I press enter to stop autostart.
Then I type the following commands :
=> setenv bootargs => fatload ace 0 400000 linux/vmlinux.uboot => bootm 400000
In fact the first command is the reason of hang up after #Uncompressing Kernel Image .... Ok My goal was to preserve command line set up in the Kernel configuration (using NFS)
If I type only the last two commands, the Kernel start properly on the root file system of the Compact Flash (due to u-boot default bootargs).
I did not succeed to run under emulator to try to figure out what's going wrong. I do not succeed to activate break points with the command (under gdb) monitor bps do_bootm hw
Is this U-boot behaviour normal?
A second question is : What is the starting point to have I2C EEPROM available on that ML403 board under U-boot to save environnement and us autostart?
Kinds regards
Chris
