Hi all, I have a custom board with an ppc8540 cpu. I'm using a vanilla Linux kernel 2.6.20.3.
The RTC chip is a PCF8563, connected to 8540's i2c controller at address 0x51. In u-boot the clock works fine ('date' command) so the hardware is alright. In Linux however, I get this at boot: (...) i2c /dev entries driver TCP cubic registered NET: Registered protocol family 1 NET: Registered protocol family 17 drivers/rtc/hctosys.c: unable to open rtc device (rtc0) (...) I have compiled in the PCF8563 rtc driver (not as module), and have support for RTC class, /dev, /proc and /sys. However, the entries in /proc and /sys relevant to the RTC remain empty. I have created a device node /dev/rtc0 with major/minor 254, 0 (254 being what is listed as rtc in /proc/devices). For some reason, PCF8563 driver does not initialize correctly. I'm looking for a hint where to look for finding the cause of this... Some further info: ARCH=ppc, CROSS_COMPILE=ppc_85xx- (from ELDK 4), boot loader is u-boot 1.2.0. Thansk for any help.
