do you have an example on how to blow fuses on i.MX25 for example
for setting the mac address or the boot configuration bits ?
Here you go:
# allow fuses blow
imx_iim_bank0.permanent_write_enable=1
# put the MAC address 02:4b:b1:71:0f:29
mw -b -d /dev/imx_iim_bank0 26+6 0x02 0x4b 0xb1 0x71 0x0f 0x29
# make the MAC address permanent (not more fuses blow)
mw -b -d /dev/imx_iim_bank0 0+1 0x04
# disallow fuses blow
imx_iim_bank0.permanent_write_enable=0
many thanks, that's a very good example of a clever usage of mw ;-)
Eric
