Is there any support for GPIO emulation on a RISC-V MCU e.g. SiFive HiFive1 Rev B
FYI: I have asked the same question on https://github.com/renode/renode/issues/723 but I figured it might not be a good place to start with. This logs mentioned below are a stripped down version of the original one, but no crucial information is lost, same goes for the references. I do not have enough reputation to post more than 8 links so I have replaced forward slashes in urls with a space (within logs only). Sorry for inconvenience if any.
I am trying to simulate a blinky application on the mentioned dev. board using PlatformIO installed on VSCodium.
Setup:
I am using the example project for SiFive platform located in C:\Users\<user_name>\.platformio\platforms\sifive\examples\native-blink_asm.
Here are the contents of platformio.ini file:
[env:sifive-hifive1-revb]
platform = sifive
framework = freedom-e-sdk
board = hifive1-revb
monitor_speed = 115200
upload_flags =
-e include @${renode.renode_root_dir}"/scripts/single-node/sifive_fe310.resc"
-e logLevel -1
-e sysbus LoadELF @$PROJECT_BUILD_DIR\$PIOENV\$PROGNAME".elf"
-e start
upload_command = ${renode.renode_root_dir}"/bin/Renode.exe" $UPLOAD_FLAGS
[renode]
renode_root_dir = C:/Users/Admin/Downloads/renode_1.15.3
Code:
I have moved the content out of while loop, and added a print statement in src\superBlink.c like so:
Main code
Output:
The code compiles successfully, gets loaded successfully in Renode, but I receive a warning: [WARNING] gpioInputs: Trying to write a pin that isn't configured for writing. Skipping.
Received warning
