Rick Chenccaabe02018-05-29 10:29:20 +08001Andes Technology SoC AE350
Rick Chend7e6f922017-12-26 13:55:59 +08002===========================
3
Rick Chenccaabe02018-05-29 10:29:20 +08004AE350 is the mainline SoC produced by Andes Technology using AX25 CPU core
Rick Chend7e6f922017-12-26 13:55:59 +08005base on RISC-V architecture.
6
Rick Chenccaabe02018-05-29 10:29:20 +08007AE350 has integrated both AHB and APB bus and many periphals for application
Rick Chend7e6f922017-12-26 13:55:59 +08008and product development.

15Configurations
16==============
17
18CONFIG_SKIP_LOWLEVEL_INIT:
19 If you want to boot this system from SPI ROM and bypass e-bios (the
20 other boot loader on ROM). You should undefine CONFIG_SKIP_LOWLEVEL_INIT
Rick Chenccaabe02018-05-29 10:29:20 +080021 in "include/configs/ax25-ae350.h".

23Build and boot steps
24====================
25
26build:
271. Prepare the toolchains and make sure the $PATH to toolchains is correct.
Rick Chen57502af2018-12-18 10:48:55 +0800282. Use `make ae350_rv[32|64]_defconfig` in u-boot root to build the image for 32 or 64 bit.

33Target
34====================
351. startup
362. relocation
373. timer driver
384. uart driver
395. mac driver
406. mmc driver
417. spi driver
42
43Steps
44====================
451. Define CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is loaded via gdb from ram.
462. Undefine CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is booted from spi rom.
473. Ping a server by mac driver
484. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver.
495. Burn this u-boot image to spi rom by spi driver
506. Re-boot u-boot from spi flash with power off and power on.
