[Gumstix-users] Kernel ignoring my bootargs

[Mino B. <mi...@mi...>]

Hi all,
I'd need to set the I2C bus speed to 100kHz, so I followed the
instructions and issued a:

 setenv bootargs i2c_bus=3,100

in uBoot, followed by a "saveenv". I can then see the option correctly
with "printenv", however these options seems to be ignored by the
kernel boot:

 root@overo:~# dmesg | grep "command line"
 Kernel command line: console=ttyS2,115200n8 vram=12M
omapfb.mode=dvi:1024x768MR-16@60 omapfb.debug=y omapdss.def_disp=dvi
root=/dev /mtdblock4 rw rootfstype2

And so the speed remains to 400kHz:

 root@overo:~# dmesg | grep i2c
 i2c_omap i2c_omap.1: bus 1 rev3.12 at 2600 kHz
 i2c_omap i2c_omap.3: bus 3 rev3.12 at 400 kHz

Am I doing anything wrong?
Thanks.
