RTC reset after power cycle - DM368 IPNC - Version 4.0

Antoine DUBOST BULARD
Intellectual 275 points

Dear All,

I noticed that on my DM368 IPNC with SW release 4.0 and after setting clock time in the web pages, the date goes back to the beginning of time (1-1-1970) avec reset/power cycle.

I suspected at first a HW problem, but my cam works fine with 2.6.0 SW release.

So i dug a little deeper and found that 2.6.37 kernel provided with 4.0 release do not integrate RTC support. I also noticed that "TI DaVinci DM365 RTC" driver was not available too, whereas it was available on 2.6.18 kernel provided with 2.6.0 release.

Is there anybody that can tell me how to make work RTC with this new Kernel (Patch / Configuration)

I found here : http://processors.wiki.ti.com/index.php/DaVinci_PSP_03.21.00.04_Release_Notes that RTC should be supported with 2.6.37

Any idea would be really appreciated, i'm a quite lost.

Thanks for advance for your help

Best regards

ADB

    Antonie,

    Have you enabled CONFIG_RTC_DRV_DAVINCI in your configuration and tried?

    Dear Renjith Thomas,

    Thanks for your feedback

    I tried this but after setting CONFIG_RTC_DRV_DAVINCI in the davinci_dm368_ipnc_defconfig_nfs, as far as TI DAVINCI RTC do not appear in the make menuconfig RTC section, I assumed that i was going in the wrong way.

    Anyway, i build a new kernel with this config for RTC : 

    CONFIG_RTC_LIB=y
    CONFIG_RTC_CLASS=y
    CONFIG_RTC_INTF_SYSFS=y
    CONFIG_RTC_INTF_PROC=y
    CONFIG_RTC_INTF_DEV=y
    CONFIG_RTC_DRV_DAVINCI=y

    I also create both rtc and rtc0 special files with mknod in /dev

    mknod rtc c 254 0 

    mknod rtc0 c 0 1  

    With this configuration, during boot, CSL driver init fail, but at the end of boot i'm able to call hwclock and see RTC current time.

    I assume the conflict is due to that both RTC and CSL driver have the same driver MAJOR number (254). What is your opinion ?

    Does anyone know how to change RTC MAJOR number to remove this conflict and make CSL and RTC work together ?

    Regards

    ADB

    Dear Antoine,

    Can you print the contents of /proc/devices and see rtc is present and major number of rtc?

    Is it normal that is find 254 for csl in /dev ls and 253 in /proc/devices ?

    Both Major number shouldn't be the same ?

    Here is the bootlog of my system, maybe i'm wrong on the real problem and this will help you to see something :

    Please note that without enabling CONFIG_RTC_INTF_DEV=y in the config file, my system boot up just fine and i'm able to cat /proc/drivers/rtc.

    To allow me to access to RTC through /dev, i want to enable CONFIG_RTC_INTF_DEV, but this cause my system boot up wring like above

    Antoine,

    If you compare the /dev/ entries and the /proc/devices entry for CSL, it is mismatching. Basically you've to change the csl devices major number to 253 instead of 254.

    Dear Renjith Thomas,

    Thanks again for your reactivity !

    You are right, the CSL Major Number in the dev entry is not the same that the CSL Major number in the /proc/devices.

    Setting the CSL to 253 do not make the things work as far I noticed there is a shift with other peripherals.

    So i recreate the nodes as follow 

    Peripheral - Wrong major number - New right major number

    csl                          254                                        253

    dev_i2c                 253                                        252         

    dev_dma              252                                        251 

    edma                    251                                        250 

    irqk                        250                                        249 

    dm365mmap       249                                        248 

    cmem                    248                                        247

    With this, all is working fine.

    Best Regards
