about AM3517 HECC bit timing & sample point problem

My bsp version is BSP_WINCE_ARM_A8_01_01_00.

HECC driver (PLATFORM\COMMON\SRC\SOC\COMMON_TI_V1\COMMON_TI\HECC\omap_hecc.cpp) in this BSP using 66.7% as its sample point.

We want to change sample point to 87.5% to meet CANOpen and DeviceNet requirement.

But we can't setting 87.5% sample point at high baud rate such as 250k 500k 800k 1000k...(omap_hecc.cpp->FindBestCanBitTiming)

Is there any solution about this?
