==========
|
||
|
|
|
||
|
|
This board configuration will use FVP_BaseR_AEMv8R to emulate
|
||
|
|
generic ARMv8-R (Cortex-R52) series hardware platform and
|
||
|
|
provides support for these devices:
|
||
|
|
|
||
|
|
- GICv3 interrupt controllers for ARMv8-r
|
||
|
|
- PL011 UART controller(FVP)

Getting Started
|
||
|
|
===============
|
||
|
|
|
||
|
|
1. Compile Toolchain
|
||
|
|
I recommend to use the docker based CI image
|
||
|
|
<nuttx>/tools/ci/docker
|
||
|
|
|
||
|
|
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:
|
||
|
|
<path_to>/AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R
|
||
|
|
Version 11.20 is tested fine.
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
$ <path_to>/AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R \
|
||
|
|
-f boards/arm/fvp-v8r-aarch32/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
|
||
|
|
|
||
|
|
3.2 Single Core
|
||
|
|
Configuring NuttX and compile:
|
||
|
|
$ ./tools/configure.sh -l fvp-armv8r-aarch32:nsh
|
||
|
|
$ make
|
||
|
|
|
||
|
|
4. Running

Step1: Booting NuttX
|
||
|
|
|
||
|
|
$ AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R \
|
||
|
|
-f boards/arm/fvp-v8r-aarch32/fvp-armv8r-aarch32/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
|
||
|
|
|
||
|
|
Step2: telnet to UART1
|
||
|
|
Starting another terminal and enter:
|
||
|
|
$ telnet localhost 5001
|
||
|
|
Trying 127.0.0.1...
|
||
|
|
Connected to localhost.
|
||
|
|
Escape character is '^]'.
