No, because we have fixed IOFPGA firmware. The 'Firmware Update' tab on http://releases.linaro.org/12.10/android/vexpress links to ARM's site to get this. Our kernel commandline also has "mmci.fmax=12000000" to select the fastest clock speed possible. -- Tixy _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
