Dear Robin,
Gosh - egg on face. Got mixed up with the PIT which usually uses a 32KHz crystal as does the RTC on the mpc860. Well, we don't have a crystal on the PIT so that (as well as the non-existant RTC) is not available!!
This is what comes from trying to rely on memory alone with 1358 pages of mpc866 manual :-))
Our target doesn't have a 32 KHz crystal, and the WDT (DENX) works OK.
Out target MPC855T uses only a 50MHz oscillator. The u-boot and Linux configuration is the same as the TQM8xx, we just added: #define CONFIG_8XX_GCLK_FREQ 50000000 in the u-boot configuration.
All our applications register with the WDT and it works OK.
Best regards, Eli Brin
