| John Tsichritzis | 4730c11 | 2019-07-05 14:14:40 +0100 | [diff] [blame] | 4 | Versatile Express (VE) family development platform provides an ultra fast |
| 5 | environment for prototyping Armv7 System-on-Chip designs. VE Fixed Virtual |
| 6 | Platforms (FVP) are simulations of Versatile Express boards. The platform in |
| 7 | Trusted Firmware-A has been verified with Arm Cortex-A5 and Cortex-A7 VE FVP's. |
| 8 | This platform is tested on and only expected to work with single core models. |

| 27 | - Obtain arm toolchain. The software stack has been verified with linaro 6.2 |
| 28 | `arm-linux-gnueabihf <https://releases.linaro.org/components/toolchain/binaries/6.2-2016.11/arm-linux-gnueabihf/>`__. |
| 29 | Set the CROSS_COMPILE environment variable to point to the toolchain folder. |
| 30 | |
| 31 | - Fetch and build u-boot. |
| 32 | Make the .config file using the command: |
| 33 | |
| 34 | .. code:: shell |
| 35 | |
| 36 | make ARCH=arm vexpress_aemv8a_aarch32_config |
| 37 | |
| 38 | Make the u-boot binary for Cortex-A5 using the command: |
| 39 | |
| 40 | .. code:: shell |
| 41 | |
| 42 | make ARCH=arm SUPPORT_ARCH_TIMER=no |
| 43 | |
| 44 | Make the u-boot binary for Cortex-A7 using the command: |
| 45 | |
| 46 | .. code:: shell |
| 47 | |
| 48 | make ARCH=arm |
| 49 | |
| 50 | |
| 51 | - Build TF-A: |
| 52 | |
| 53 | The make command for Cortex-A5 is: |
| 54 | |
| 55 | .. code:: shell |
| 56 | |
| 57 | make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A5=yes \ |
| 58 | AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A5x1.dts \ |
| 59 | ARM_XLAT_TABLES_LIB_V1=1 BL33=<path_to_u-boot.bin> all fip |
| 60 | |
| 61 | The make command for Cortex-A7 is: |
| 62 | |
| 63 | .. code:: shell |
| 64 | |
| 65 | make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A7=yes \ |
| 66 | AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A7x1.dts \ |
