Hi, I am trying to compile new kernel to test GPIO pins, however, no success for some time - kernel linking ends with error: linking kernel.debug ld: kernel.debug: warning: allocated section `.sdata' not in segment ethernet-common.o: In function `cvm_assign_mac_address': /usr/src/sys/mips/cavium/octe/ethernet-common.c:110: undefined reference to `cvmx_mgmt_port_num_ports' /usr/src/sys/mips/cavium/octe/ethernet-common.c:110: relocation truncated to fit: R_MIPS_26 against `cvmx_mgmt_port_num_ports' *** Error code 1 Searching in /sys/mips/cavium for cvmx_mgmt_port_num_ports is not successfull - any insight here?
