ESP32-S3 documentation (QEMU-201) #98

Open PatrickV82 opened 3 months ago

PatrickV82 commented 3 months ago

I am trying to use the ESP32-S3 implementation that was released with the version 9.0.0

I have the following questions:

  1. Is there a updated documentation for the bootstrapping pins values?
  2. Does the esp32s3 implementation already support the efuses?
  3. Does the esp32s3 implementation support Flash Encryption and SecureBoot ?

When i try to use the efuse in the same manor as the ESP32-C3 i get the following error

qemu-system-xtensa -nographic -machine esp32s3 -global driver=esp32s3.gpio,property=strap_mode,value=0x08 -drive file=build/qemu_efuse.bin,if=none,format=raw,id=efuse -global driver=nvram.esp32s3.efuse,property=drive,value=efuse -serial tcp::5555,server,nowait

QEMU 9.0.0 monitor - type 'help' for more information Not initializing SPI Flash c:\qemu\bin\qemu-system-xtensa: warning: global nvram.esp32s3.efuse.drive has invalid class name

Hi @PatrickV82,

Currently there is a stub of eFuse implementation for ESP32-S3, which is simply a copy of the one from ESP32-C3. I think if you replace driver=nvram.esp32s3.efuse with driver=nvram.esp32c3.efuse then QEMU will run. However, I am not sure yet how different ESP32-C3 and ESP32-S3 eFuse modules are, so this might not actually work with ESP-IDF or esptool.

We'll update this issue once ESP32-S3 eFuse support is done!

To get into the download mode on ESP32-S3, set the strapping value to 0x07.

@igrr is there support for openeth driver in qemu for esp32s3? I've tried to build but had some issue around openeth not building for esp32s3 target (but ok for esp32)

@greenaddress It should have been added in https://github.com/espressif/esp-idf/commit/f95caa75. Have you enabled CONFIG_ETH_USE_OPENETH in menuconfig?

@igrr We are on 5.2.2 right now, hope 5.2.3 or 5.3.x will have it
