On OMAP2/3 GPTIMER1, this can cause the timer -counter register to warp to unknown values or miss interrupt -conditions. So, use GPTIMER12 instead, which apparently has its own -secure 32kHz oscillator and will hopefully not be prone to the 32kHz -glitches. ---- - - arch/arm/configs/omap3_beagle_defconfig | 5 +++-- - 1 files changed, 3 insertions(+), 2 deletions(-) - -diff --git a/arch/arm/configs/omap3_beagle_defconfig b/arch/arm/configs/omap3_beagle_defconfig -index e1b16d0..7805995 100644 ---- a/arch/arm/configs/omap3_beagle_defconfig -+++ defconfig -@@ -182,8 +182,8 @@ CONFIG_OMAP_BOOT_REASON=y - # CONFIG_OMAP_MCBSP is not set - # CONFIG_OMAP_MMU_FWK is not set - # CONFIG_OMAP_MBOX_FWK is not set --CONFIG_OMAP_MPU_TIMER=y --# CONFIG_OMAP_32K_TIMER is not set -+# CONFIG_OMAP_MPU_TIMER is not set -+CONFIG_OMAP_32K_TIMER=y - CONFIG_OMAP_DM_TIMER=y - # CONFIG_OMAP_LL_DEBUG_UART1 is not set - # CONFIG_OMAP_LL_DEBUG_UART2 is not set -@@ -198,6 +198,7 @@ CONFIG_ARCH_OMAP3430=y - # CONFIG_MACH_OMAP_3430SDP is not set - # CONFIG_MACH_OMAP3EVM is not set - CONFIG_MACH_OMAP3_BEAGLE=y -+CONFIG_OMAP_TICK_GPTIMER=12 - - # - # Boot options |
