==========
|
||
|
||
This board configuration will use FVP_BaseR_AEMv8R to emulate
|
||
generic ARM64v8-R (Cotex-R82) series hardware platform and
|
||
provides support for these devices:
|
||
|
||
- GICv3 interrupt controllers for ARMv8-r
|
||
- PL011 UART controller(FVP)

Getting Started
|
||
===============
|
||
|
||
1. Compile Toolchain
|
||
The FVP platform using same Compiler like qemu, read the following
|
||
file for How to get the Tool:
|
||
https://github.com/apache/nuttx/tree/master/boards/arm64/qemu/qemu-armv8a
|
||
|
||
Note:
|
||
1 My host environment is Ubuntu 22.04.1 LTS, Ubuntu 18.04 will work too
|
||
2 The newest GNU toolchain is 12.2, available from:
|
||
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
|
||
|
||
|
||
2. Getting Armv8-R AEM FVP
|
||
The Armv8-R AEM FVP is a free of charge Armv8-R Fixed Virtual Platform.
|
||
It supports the latest Armv8-R feature set. we can get it from:
|
||
https://developer.arm.com/downloads/-/arm-ecosystem-models
|
||
|
||
Please select to download Armv8-R AEM FVP product, extract the tool package
|
||
the FVP tool is locate at:
|
||
AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R
|
||
|
||
3. Configuring and building
|
||
3.1 FVP Overview
|
||
Just like QEMU, Fixed Virtual Platforms (FVP) are complete simulations of an Arm system,
|
||
including processor, memory and peripherals. These are set out in a "programmer's view",
|
||
which gives you a comprehensive model on which to build and test your software.
|
||
|
||
The FVP tools simulate 4 serial port and implement them to wait on local socket port:
|
||
|
||
$ /home/qinwei/workdir/tools/AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R \
|
||
-f boards/arm64/fvp-v8r/fvp-armv8r/scripts/fvp_cfg.txt -a ./nuttx
|
||
terminal_0: Listening for serial connection on port 5000
|
||
terminal_1: Listening for serial connection on port 5001
|
||
terminal_2: Listening for serial connection on port 5002
|
||
terminal_3: Listening for serial connection on port 5003
|
||
|
||
FVP has four UART port and I choice UART1 as tty, so just telnet to port 5001
|
||
will enter nsh:
|
||
telnet localhost 5001
|
||
|
||
3.1 Single Core
|
||
Configuring NuttX and compile:
|
||
$ ./tools/configure.sh -l fvp-armv8r:nsh
|
||
$ make
|
||
|
||
3.2 SMP
|
||
Configuring NuttX and compile:
|
||
$ ./tools/configure.sh -l fvp-armv8r:nsh_smp
|
||
$ make
|
||
|
||
4. Running
