[U-Boot-Users] Walnut405 PPC hang prob at linux startup

Hi
I am using u-boot 1.0.0, and am loading linux kernel at 400000, it appears to hang after printing message - "Warning: real time clock seems stuck!"
My linux kernel version is 2.4.18
I have put additional kprint in main.c and am able to track it down to between the lines
. . . kmem_cache_init(); sti(); . .
I have tried to set clocks_in_mhz to 1 through the setenv command and it did not help.
I have already checked time.c and it is 1.35 11/28/01, and has the following code
if (ppc_md.get_rtc_time) { stamp = get_native_tbl(); sec = ppc_md.get_rtc_time(); elapsed = 0; do { old_stamp = stamp; old_sec = sec; stamp = get_native_tbl(); if (__USE_RTC() && stamp < old_stamp) old_stamp -= 1000000000; elapsed += stamp - old_stamp; sec = ppc_md.get_rtc_time(); } while ( sec == old_sec && elapsed < 2*HZ*tb_ticks_per_jiffy); if (sec==old_sec) { printk("Warning: real time clock seems stuck!\n"); } write_lock_irqsave(&xtime_lock, flags); xtime.tv_sec = sec; last_jiffy_stamp(0) = tb_last_stamp = stamp; xtime.tv_usec = 0; /* No update now, we just read the time from the RTC ! */ last_rtc_update = xtime.tv_sec; write_unlock_irqrestore(&xtime_lock, flags); } else { stamp = get_native_tbl(); last_jiffy_stamp(0) = tb_last_stamp = stamp; }
I will appreciate any helpregarding this.
Thanks A. Dadabhoy

It cannot help, as it is completely wrong. You must UNDEFINE the variable.

Thank for a quick reply.
I forgot to mention that tries both ways, i.e. I also undefined the variable and yet it fails. Any other suggestion ?
Thanks
