Andes Technology SoC AG101P |
||||
=========================== |
||||
|
||||
AG101P is the mainline SoC produced by Andes Technology using N1213 CPU core |
||||
with FPU and DDR contoller support. |
||||
AG101P has integrated both AHB and APB bus and many periphals for application |
||||
and product development. |
||||
|
||||
ADP-AG101P |
||||
========= |
||||
|
||||
ADP-AG101P is the SoC with AG101 hardcore CPU. |
||||
|
||||
Configurations |
||||
============== |
||||
|
||||
CONFIG_MEM_REMAP: |
||||
Doing memory remap is essential for preparing some non-OS or RTOS |
||||
applications. |
||||
|
||||
CONFIG_SKIP_LOWLEVEL_INIT: |
||||
If you want to boot this system from SPI ROM and bypass e-bios (the |
||||
other boot loader on ROM). You should undefine CONFIG_SKIP_LOWLEVEL_INIT |
||||
in "include/configs/adp-ag101p.h". |
||||
|
||||
Build and boot steps |
||||
==================== |
||||
|
||||
build: |
||||
1. Prepare the toolchains and make sure the $PATH to toolchains is correct. |
||||
2. Use `make adp-ag101p_defconfig` in u-boot root to build the image. |
||||
|
||||
Burn u-boot to SPI ROM: |
||||
==================== |
||||
|
||||
This section will be added later. |
