Qemu environment problem for ESP32-C3

Posted: Sat Jan 13, 2024 9:35 pm

Hello
First of all, it's my first post here, so welcome everyone.
What I'm trying to do is to prepare an environment for biggier project but instead of flashing all the time, I want to run qemu to test first.
The real/future target is ESP32-C3, custom hardware provided by external party, so no way to change chip type.
IDE is VSCode/P.IO, code using Arduino framework (that's why it's posted here)
So... I've created a simple project

Code: Select all

[env:esp32-c3-devkitm-1-qemu]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino
monitor_speed = 115200
upload_speed = 921600
upload_protocol = custom
extra_scripts = qemu_build.py

Code: Select all

#include <Arduino.h>
void setup() {
  Serial.print("setup\n");
}
int cnt = 0;
void loop() {
  Serial.printf("counter=%d\n", cnt++);
  delay(1000);
}
In the qemu_build.py I have custom actions for creating an image and running the qemu

esptool.py --chip esp32c3 merge_bin --flash_mode dio --flash_freq 80m --flash_size 4MB --fill-flash-size 4MB -o qemu_firmware.bin 0x0 bootloader.bin 0x8000 partitions.bin 0xe000 C:\Users\Szefu\.platformio\packages\framework-arduinoespressif32\tools\partitions\boot_app0.bin 0x10000 firmware.bin

qemu-system-riscv32.exe -nographic -no-reboot -machine esp32c3 -icount 3 -drive file=D:\PlatformIO\Projects\qemu_test\.pio\build\esp32-c3-devkitm-1-qemu\qemu_firmware.bin,if=mtd,format=raw

Build log is

Code: Select all

platformio.exe run --environment esp32-c3-devkitm-1-qemu

Now the error is
assert failed: do_core_init startup.c:328 (flash_ret == ESP_OK)

which I googled already and only found information that this is mismatch on flash size, but the merge_bin and the git hub doc on C3 qemu saying 4MB both, so i don't see any issue here.

I would greatly appreciate any help with this.

It is trying to init the SPI flash device, and failing. How is the emulator presenting the flash?
And, as a side note, have you tried out https://wokwi.com ?

Hi lbernstone
I did some further testing and when i build the project in VSC/P.IO but with ESP-IDF framework it works fine.
Merge and qemu commands are extaclty the same.
So apparently some "spells" are needed for Arduino build and Wokwi knows them.
I didn't find anything about it, so I'll have to go IDF way.

If you are working from a command line, building with 'framework = espidf, arduino' may get you the necessary magic.

WOW :shock:
I would never think you can mix those.
But now this works with arduino code, big thanks!!!
