Strange! with this u-boot my DUT GTA02 happily loads kernel, but **kernel** **hangs** (stops boot-up) on "pcf50633 setting up system time xxxxxxxxx critfail xxx". Inserting bat at this point makes kernel continue (next line on console is "xxx empty NAND...xxx" IIRC), but removing bat immediately gives a "xxxx failed to report bat-voltage properly... xxx" and DUT shuts down same second. on same DUT the factory NOR-uboot (=holding AUX while inserting USB) happily boots all the way to 2008.08 desktop, no battery needed, no hangups, no shutdown hmmmm... !???! btw: booting by USB-insert with this u-boot/kernel does NOT lite up AUX. Taking out and reinserting bat lits AUX. /jOERG
