JBR20 (upgraded with Tosh 60GB HDD)
Rockbox in Flash
Mask: 0x0302
USB: positive
ATA: 0x200,master
PR: positive
Flash: M=BF D=D6
ROM CRC:0x222F V1

(Note: this bug only applies with Rockbox in Flash)
With the power adapter attached, the JBR charges
when in idle or play mode.

However, if I turn the JBR off (holding the OFF button)
the LCD remains lit (though flashes off for a millisecond
every 1-2 seconds), displays "not charging" regadless of
how long the JBR is left. The batteries do not seem to
charge when in this state. Workaround: unplug the
mains and re-insert - the Rockbox charge screen is
displayed normally and charging starts as normal.

This bug is only a real problem when the unit is plugged
into the mains and the the 'Sleep' option is used - as
the workaround is not possible if you're asleep! :-)
This task depends upon

This bug is as old as the dinosaurs. The battery charging
algorithm has been revised since then. Chances are that this
issue doesn't exist anymore.
