We have 10G link between FPGA and T4240 through backplane. Now we are trying to configure 10GBASE-KR.
In Reference Manual 126.96.36.199 XFI/10FBase-KR said modified, Transmit Equalization Control Register 0 LNnTECR0, following the procedure in Lane Reset and Reconfiguration. Next no visibility that 10GBase-KR is on. There is no trying Auto-Negotiation or Link-training from T4240. Also reading mdio registers MDIO_XFI_PMD_CR1 and MDIO_XFI_10GKR_PMD_CR indicate that 10GBase-KR not enable.
What we need to do, or which registers can help us to figure out our issue?
