An output like the following is not helpful: Timer summary in microseconds (40 records): Mark Elapsed Stage 0 0 reset ... 56,448,158 4,845 fit_image_load 56,448,186 28 fit_image_load 56,448,187 1 fit_image_load 56,451,971 3,784 fit_image_load 56,483,951 31,980 fit_image_load 56,483,956 5 fit_image_load 56,483,984 28 fit_image_load 56,484,001 17 fit_image_load 56,484,008 7 fit_image_load
It provides no clue about what is happening in the fit_image_load stage. Add the bootstage ID to the report. Now we get: Timer summary in microseconds (40 records): Mark Elapsed ID Stage 0 0 171 reset 3,181,017 3,181,017 178 board_init_f 3,229,282 48,265 179 board_init_r 4,184,866 955,584 64 eth_common_init 4,280,304 95,438 65 eth_initialize 4,284,509 4,205 186 main_loop 4,390,704 106,195 180 usb_start 5,694,146 1,303,442 187 cli_loop 59,908,029 54,213,883 184 bootm_start 59,908,031 2 1 boot_get_kernel 59,912,875 4,844 100 fit_image_load 59,912,903 28 101 fit_image_load 59,912,904 1 102 fit_image_load 59,916,688 3,784 110 fit_image_load 59,948,668 31,980 105 fit_image_load 59,948,673 5 106 fit_image_load ...
