| |
| 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: |
| |
| 1. startup |
| 2. relocation |
| 3. timer driver |
| 4. uart driver |
| 5. mac driver |
| 6. mmc driver |
| 7. spi driver |
| |
| Steps |
| ----- |
| |
| 1. Ping a server by mac driver |
| 2. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver |
| 3. Burn this u-boot image to spi rom by spi driver |
| 4. Re-boot u-boot from spi flash with power off and power on |

| Running U-Boot SPL |
| ------------------ |
| The U-Boot SPL will boot in M mode and load the FIT image which include |
| OpenSBI and U-Boot proper images. After loading progress, it will jump |
| to OpenSBI first and then U-Boot proper which will run in S mode. |
| |
| |
| How to build U-Boot SPL |
| ----------------------- |
| Before building U-Boot SPL, OpenSBI must be build first. OpenSBI can be |
| cloned and build for AE350 as below: |
| |
| .. code-block:: none |
| |
| git clone https://github.com/riscv/opensbi.git |
| cd opensbi |
| make PLATFORM=andes/ae350 |
| |
| Copy OpenSBI FW_DYNAMIC image (build/platform/andes/ae350/firmware/fw_dynamic.bin) |
| into U-Boot root directory |
| |
| |
| How to build U-Boot SPL booting from RAM |
| ---------------------------------------- |
| With ae350_rv[32|64]_spl_defconfigs: |
| |
| U-Boot SPL will be loaded by gdb or FSBL and runs in RAM in machine mode |
| and then load FIT image from RAM device on AE350. |
| |
| |
| How to build U-Boot SPL booting from ROM |
| ---------------------------------------- |
| With ae350_rv[32|64]_spl_xip_defconfigs: |
| |
| U-Boot SPL can be burned into SPI flash and run in flash in machine mode |
| and then load FIT image from SPI flash or MMC device on AE350. |
| |
