On an original (v1) Sansa e250 I cannot get Rockbox (current build as of 20 may 09) to charge the battery. Under Debug -> view battery I see Battery 3.6 V (elsewhere this is interpreted as 8% charge), Charger: present, State: Discharging. My read through the code seems to indicate that the charger should be enabled under these conditions. Am I missing something or is this a bug?
A little more background/information: This e250 will not charge in the original firmware either. I believe that the reason is the value of ADC_BVDD when a charger or USB is plugged in. When I view the I/O values under debug I get: NO Charger ADC_BVDD = ~730 ADC_RTCSUP = ~730 USB or Wall charger connected ADC_BVDD = ~930 ADC_RTCSUP = ~730 I have seen this noted as a problem and the code theoretically uses ADC_RTCSUP instead of the flakey ADC_BVDD. This is confirmed by doing the conversion to volts which read 3.6 whether the charger is plugged in or not. This, in principle, seems like it should solve my battery charging problems. Does anyone know why this would not trigger a call to enable_charger() making the charge_state go to CHARGING? Tony ============= Anthony Whipple [email protected]
