SDK Configuration

Typical configuration commands:

m menuconfig
m kernel_menuconfig
m rtos_menuconfig

Board configuration is normally under:

device/config/chips/v821/configs/<board>/

SoC-level DTSI and BSP settings are under:

bsp/configs/linux-5.4-ansc/

Validate the final DTB:

dtc -I dtb -O dts -o final.dts <board>.dtb

Partition example:

[partition]
name         = boot-resource
size         = 1024
downloadfile = "boot-resource.fex"
user_type    = 0x8000

UART settings may be stored in sys_config.fex:

[uart_para]
uart_debug_port = 0
uart_debug_tx = port:PD22<3><1><default><default>
uart_debug_rx = port:PD23<3><1><default><default>
