For example, if you find that the performance of MA35D0/MA35H0 does not meet your requirements, you can opt for a higher-tier chip, such as the MA35D1. Before changing the chip, remember to check the number of peripherals such as CAN-FD, UART, etc. In the software part, we recommend downloading a ne...

The default size of the root file system depends on the packages you choose to install. If you require an expansion of the root file system to its maximum capacity, options are available through Buildroot's menuconfig or Yocto's recipe configuration Buildroot $ make menuconfig Bootloaders ---> [*] A...

Nuvoton offers a default configuration as you initiate image building. However, there are instances where this might prove insufficient or where you wish to alter the configuration. In such cases, the "make menuconfig" command serves as a tool to make necessary modifications. At times, you might fin...

The booting time of an image created using Buildroot is faster compared to Yocto, primarily because Buildroot employs the busybox system, whereas Yocto utilizes the systemd system. If your goal is to further decrease the booting time, an effective approach is to deactivate the console log, which sig...

If you employ Buildroot for building the MA35D1 Image, you'll notice that attempting to modify the U-Boot environment does not take effect. This is due to the environment being overwritten upon completion of the compilation process. The actual U-Boot environment resides at: /board/nuvoton/ma35d1/ubo...

Running certain applications may result in a large amount of cache and logs being stored in the /run/log/journal and /var/run/journal directories, which can consume a significant amount of disk space and potentially cause system errors. To address this issue, you can limit the size of the systemd lo...
