QI kernel parameters

[Ed Kapitein]

Hi Phil,

Thanks for the tip, it seems like a hassle to recompile qi for setting
the glamo clock speed.
Anyway, i tried it, and i end up with:
neo qi # make
mkdir -p image
ld: cannot open linker script file src/cpu//qi.lds: No such file or
directory
make: *** [image/qi--master_c38b062a609f1442.udfu] Error 1
I am building on the FR, so no toolchain there.

Did you manage to get your SD card to work? if so how?
Also in my case the error follows the SD card, another card (class 6)
works just fine, but the new (class 4)
is buggy.

Kind regards,
Ed
