Just realized my mistake. The method I used (writing \x10 to TP_CTRL1 using sunxi-dbgreg.ko) led to bit 7 being cleared and therefore setting CHOP_TEMP_EN from enable to disable. Restoring the default by writing \x90 to TP_CTRL1 gives temperature readouts way closer to reality. If CHOP_TEMP_EN is disabled the temperatures reported show in some situations a rather large offset to the actual temperatures in one or the other direction. If CHOP_TEMP_EN is enabled the deviation is much smaller. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
