Hi Vincent, > static const struct can_tdc_const es58x_tdc_const = { > .tdcv_min = 0, > .tdcv_max = 0, /* Manual mode not supported. */ > .tdco_min = <Minimum value wTDO can take, should be documented somewhere>, > .tdco_max = <Maximum value wTDO can take, should be documented somewhere>, > .tdcf_min = 0, > .tdcf_max = 0, /* Manual mode not supported. */ }; I checked the relevant documentation,. .tdco_min should be 0 and .tdco_max 4095. Thank you for your hints! Best regards Markus
