See common/startup.c:110 #ifdef CONFIG_ENV_HANDLING if (envfs_load(default_environment_path, "/env")) { #ifdef CONFIG_DEFAULT_ENVIRONMENT printf("no valid environment found on %s. " "Using default environment\n", default_environment_path); envfs_load("/dev/defaultenv", "/env"); #endif By default default_environment_path="/dev/env0", but it can be overwritten in a board code (e.g. see arch/arm/boards/panda/board.c). -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
