Thanks very much, It really works after correct some mips-elf-gcc/ld etc symlinks. In addition, I notice http://www.nuttx.org/Documentation/NuttX.html say gnu toolchains based on buildroot for many architectures. So for AVR gcc toolchains, I just found https://www.microchip.com/mplab/avr-support/avr-and-arm-toolchains-c-compilers , but not right for nuttx. Do I need to build based on builtroot?
