Andes Technology SoC AE350
|
|
===========================
|
|
|
|
AE350 is the mainline SoC produced by Andes Technology using AX25 CPU core
|
|
base on RISC-V architecture.
|
|
|
|
AE350 has integrated both AHB and APB bus and many periphals for application
|
|
and product development.
|
|
|
|
AX25-AE350
|
|
=========
|
|
|
|
AX25-AE350 is the SoC with AE350 hardcore CPU.
|
|
|
|
Configurations
|
|
==============
|
|
|
|
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/ax25-ae350.h".
|
|
|
|
Build and boot steps
|
|
====================
|
|
|
|
build:
|
|
1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
|
|
2. Use `make ae350_rv[32|64]_defconfig` in u-boot root to build the image for 32 or 64 bit.
|
|
|
|
Verification
|
|
====================
|
|
|
|
Target
|
|
====================
|
|
1. startup
|
|
2. relocation
|
|
3. timer driver
|
|
4. uart driver
|
|
5. mac driver
|
|
6. mmc driver
|
|
7. spi driver
|
|
|
|
Steps
|
|
====================
|
|
1. Define CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is loaded via gdb from ram.
|
|
2. Undefine CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is booted from spi rom.
|
|
3. Ping a server by mac driver
|
|
4. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver.
|
|
5. Burn this u-boot image to spi rom by spi driver
|
|
6. Re-boot u-boot from spi flash with power off and power on.
