Hello,
Some months ago, a patch was submitted ([ARM] fix timer overflow in DaVinci). The result was that in /cpu/arm926ejs/davinci/timer.c read_timer was divided by 16.
http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commit;h=ea686f52e4 5b3df2938866d3f5a98bb2556dfe2b
Right now, when I have my bootdelay variable (on a DVEVM) set to 2, and countdown takes 32 seconds... Also iprobe got very very very slow. Maybe more items are affected by this timer division.
Is anybody else seeing this? Clearly when the timer is used by several blocks, it cannot be easily divided by 16. I think we need something else to work with the wrap around of the timer...
Best regards, Pieter
