On one hand it is very light weight: less than 4k LOC and 16 kB executable (which fits completely in the first stage of SRAM), so it is easier to grasp compared to U-Boot: https://github.com/trini/u-boot/search?q=sunxi&type=Code On the other hand, it has different goals and is just meant to load a blob of instructions over ethernet (faster evaluation cycle) not an entire Linux kernel with all the POSIX / UNIX stuff from SD. So you have far more control but are also on a lower level, somewhat like developing for a more powerful Arduino. |
