Most of the board's telemetry sensors (temperatures, voltages) are functional but detailed testing is to follow. We are weaning ourselves off TI's "official" kernel for this SOC, which has been stuck at 2.6.37 and is not really fit for use. To anyone at TI: despite good silicon and some dedicated support enginers, your open-source software strategy for these parts has not worked well. Please get in touch with me if you'd like to have a constructive discussion about ways to improve it.
