Hi,
I've applied the patches in
http://lists.infradead.org/pipermail/linux-arm-kernel/2011-March/045283.html
on top of a linaro kernel which resulted in booting problem on Pandaboard.
It hangs inside the cti_unlock() while reading the LOCKSTATUS value, which
happens when omap_init_pmu() is called. Please help me debug the issue.
Please check if l3 clocks are enabled to drive CTI, such as done in below:
omap_writel(1, CM_L3INSTR_L3_3_CLKCTRL);
omap_writel(1, CM_L3INSTR_L3_INSTR_CLKCTRL);
omap_writel(2, CM_EMU_CLKSTCTRL);
while ((omap_readl(CM_EMU_CLKSTCTRL)& 0x300) != 0x300);
Can you please tell me where should I insert the above code to enable l3
clocks to drive CTI?
Regards,
Avik
No such issue on mainline since this clocks are enabled automatically.
thanks,
