New Revision: 4118
Modified:
trunk/src/target/u-boot/patches/gta02-splash.patch
trunk/src/target/u-boot/patches/uboot-gta02.patch
Log:
Driving nDL_GSM low caused the GSM modem to inject communication requests
into the audio system, causing the characteristical clicking sound of a
GTA02 starting up, and these requests also caused lots of interrupts on
JACK_INSERT, slowing down the CPU.
This patch sets nDL_GSM high by default, and lowers it only when we turn
the modem on or off. (Under Linux, there nDL can be controlled separately
with /sys/devices/platform/neo1973-pm-gsm.0/download)
uboot-gta02.patch:
- board/neo1973/gta02/gta02.c (neo1973_gsm): make "neo1973 gsm on" also turn
off the nDL_GSM line (thus enabling downloads), and "neo1973 gsm off" turn
it on again (thus avoiding all the nasty side-effects)
- board/neo1973/gta02/gta02.c (board_init): turn GPJ6/nDL_GSM on by default
(thus enabling downloads and getting rid of all the weird effects caused by
this)
gta02-splash.patch: refreshed for above changes
