environment
Loader Type is set uboot environment variables, the image of environment type into SPI NAND Flash
in the specified address. U-Boot reads environment variables file to set the environment. If image start
offset is equal to 0x80000, download the image of data into SPI NAND Flash at the address 0x80000.
You can create a TXT file extension and add contents. NuWriter will transform env.txt to an environment
image and download the image to SPI NAND.
Here is an example for NuMaker-IIoT-NUC980G2D environment variables:
baudrate=115200
bootdelay=1
stderr=serial
stdin=serial
stdout=serial
loadkernel=nand read 0x7fc0 0x200000 0x800000
loaddtb=nand read 0x1400000 0x180000 0x20000
bootcmd=run loadkernel;run loaddtb;bootm 0x07fc0 - 0x1400000
