ESP32-S3 REPL error.
port-esp32
Hi all.
Is no possible to access the REPL on the ESP32-S3. Details below:
Operating System
Ubuntu 20.4
Module Description
Chip is ESP32-S3 - module ESP32-S3-WROOM-1 (ESP32-S3R2)
Kit Description
PartNumber: ESP32-S3-DEVKITC-1-N8R2
Is is an ESP32-S3 -DevKitC-1 v1.6 from espressif using the module ESP32-S3-WROOM-1 (ESP32-S3R2)
https://www.digikey.com/en/products/detail/espressif-systems/ESP32-S3-DEVKITC-1-N8R2/15199627
I have REPL error on that kit.
PS: I tested REPL using the UART and USB on KIT and no success.
The erase flash and write flash with MicroPython 1.18 works all fine, but I can't to access the REPL. I tested via picocom and mpremote. I tried to write a python file using the ampy and nothing.
I'm using this firmware: https://micropython.org/download/GENERIC_S3_SPIRAM/
As I'm using a module (ESP32-S3-WROOM-1 (ESP32-S3R2)) that use the SPIRAM, I get the SPIRAM firmware. Is that correct?
Is that a bug or Am I doing something wrong?
