[ts-7000] RTC Problem TS7400

["Fabio Vaz" <>]

Hi,

 

I managed to boot TS Kernel 2.6.21 on my ts7400. The problem I have now is that the RTC is not working. With kernel 2.4 it works.

 

I insert the following modules:

insmod rtc-core.ko

insmod rtc-proc.ko

insmod rtc-sysfs.ko

insmod rtc-dev.ko

insmod rtc-m48t86.ko

 

 

The syslog shows :

rtc-m48t86 rtc-m48t86: rtc core: registered m48t86 as rtc0

rtc-m48t86 rtc-m48t86: battery ok

 

I make a symbolic link /dev/rtc to rtc0:

ln -s /dev/rtc0 /dev/rtc

 

If I try to use the hwclock :

:root# hwclock --show

The Hardware Clock registers contain values that are either invalid (e.g. 50th day of month) or beyond the range we can handle (e.g. Year 2095).

 

:root# hwclock --hctosys

The Hardware Clock registers contain values that are either invalid (e.g. 50th day of month) or beyond the range we can handle (e.g. Year 2095).

 

My kernel .config file has :

#

# Real Time Clock

#

CONFIG_RTC_LIB=y

CONFIG_RTC_CLASS=m

 

#

# RTC interfaces

#

CONFIG_RTC_INTF_SYSFS=m

CONFIG_RTC_INTF_PROC=m

CONFIG_RTC_INTF_DEV=m

CONFIG_RTC_INTF_DEV_UIE_EMUL=y

 

#

# RTC drivers

#

# CONFIG_RTC_DRV_CMOS is not set

# CONFIG_RTC_DRV_DS1553 is not set

# CONFIG_RTC_DRV_DS1742 is not set

CONFIG_RTC_DRV_M48T86=m

CONFIG_RTC_DRV_EP93XX=m

# CONFIG_RTC_DRV_PL031 is not set

# CONFIG_RTC_DRV_TEST is not set

# CONFIG_RTC_DRV_V3020 is not set

 

 

I found something about this on : http://tech.groups.yahoo.com/group/ts-7000/message/10463 but I couldn’t get the .config or the patch it refers.

 

Best,

Fabio.
