Subject: [U-Boot] nds32: ag101/ag102: Inconsistent timer3 counter unit?
Date: Wed, 03 Jul 2013 23:17:32 +0800 [thread overview]
Message-ID: <1372864652.4800.3.camel@phoenix> (raw)
Hi Macpaul,
For the case CONFIG_FTTMR010_EXT_CLK is not defined:
In reset_timer_masked():
lastdec = readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2);
In get_timer_masked():
ulong now = readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2 / 1024);
The code looks strange.
(Why one needs to be divided by 1024 and the other one does not?)
I'm not sure which one is correct.
Regards,
Axel
