Rick Chen | ccaabe0 | 2018-05-29 10:29:20 +0800 | [diff] [blame] | 4 | AE350 is the mainline SoC produced by Andes Technology using AX25 CPU core |
Rick Chen | d7e6f92 | 2017-12-26 13:55:59 +0800 | [diff] [blame] | 5 | base on RISC-V architecture. |
| 6 | |
Rick Chen | ccaabe0 | 2018-05-29 10:29:20 +0800 | [diff] [blame] | 7 | AE350 has integrated both AHB and APB bus and many periphals for application |
Rick Chen | d7e6f92 | 2017-12-26 13:55:59 +0800 | [diff] [blame] | 8 | and product development. |

| 15 | Configurations |
| 16 | ============== |
| 17 | |
| 18 | CONFIG_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 Chen | ccaabe0 | 2018-05-29 10:29:20 +0800 | [diff] [blame] | 21 | in "include/configs/ax25-ae350.h". |
Rick Chen | d7e6f92 | 2017-12-26 13:55:59 +0800 | [diff] [blame] | 22 | |
| 23 | Build and boot steps |
| 24 | ==================== |
| 25 | |
| 26 | build: |
| 27 | 1. Prepare the toolchains and make sure the $PATH to toolchains is correct. |
Rick Chen | 57502af | 2018-12-18 10:48:55 +0800 | [diff] [blame] | 28 | 2. Use `make ae350_rv[32|64]_defconfig` in u-boot root to build the image for 32 or 64 bit. |
Rick Chen | d7e6f92 | 2017-12-26 13:55:59 +0800 | [diff] [blame] | 29 | |
| 30 | Verification |
| 31 | ==================== |
| 32 | |
| 33 | Target |
| 34 | ==================== |
| 35 | 1. startup |
| 36 | 2. relocation |
| 37 | 3. timer driver |
| 38 | 4. uart driver |
| 39 | 5. mac driver |
| 40 | 6. mmc driver |
| 41 | 7. spi driver |
| 42 | |
| 43 | Steps |
| 44 | ==================== |
| 45 | 1. Define CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is loaded via gdb from ram. |
| 46 | 2. Undefine CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is booted from spi rom. |
| 47 | 3. Ping a server by mac driver |
| 48 | 4. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver. |
| 49 | 5. Burn this u-boot image to spi rom by spi driver |
| 50 | 6. Re-boot u-boot from spi flash with power off and power on. |
