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 new development environment and restarting the compilation process. The following steps will guide you through cleaning and updating the environment.

Buildroot:
1. Back up data, regardless of any modifications made
2. Clean all the old image

Code: Select all

# make clean

3. It's better to update the entire environment
Notice: Do not remove the wrong folder

Code: Select all

# rm -rf dl/
# git pull

4. Set new chip’s configuration

Code: Select all

# make numaker_som_ma35d16a81_defconfig

5. Start to compile a new image

Code: Select all

# make

Yocto:
Regarding Yocto, you only need to change the configuration to the desired chip.
1. Change the MACHINE parameter to the part number you need.

Code: Select all

# vim build/conf/local.conf
MACHINE ??= ' numaker_som_ma35d16a81'
DISTRO ?= 'nvt-ma35d1-directfb'
PACKAGE_CLASSES ?= "package_rpm"

2. Start to compile a new image
