Fail to boot with dual UART on S2 with esp-idf

swifty99 commented 2 weeks ago

The problem

Since around 2024.04 two configured UARTs on a S2 Board will fail to boot.

It was working OK until 2024.03. It is working with Arduino IDE If either of the two UARTs is removed everything is fine

I really would like to stay at IDF as it did feel a lot more responsive on Home Assistant.

Which version of ESPHome has the issue?

2024.6.6

What type of installation are you using?

pip

Which version of Home Assistant has the issue?

not related

What platform are you using?

ESP32-IDF

Board

S2-mini

Component causing the issue

UART

Example YAML snippet

esphome:
  name: nouart

  on_boot:
    priority: 600
    then:
      - output.set_level:
          id: status_led
          level: 5%

external_components:
  - source: github://KinDR007/VictronMPPT-ESPHOME@main
  - source: github://syssi/esphome-jbd-bms@main

esp32:
  board: lolin_s2_mini  
  framework:
    type: esp-idf
    #type: arduino

wifi:
  networks:
  - ssid: "Wifier"
    password: !secret wifi_pw_home 

logger:
  level: DEBUG

api:

ota:
  platform: esphome

uart:
  - id: uart_jbd
    baud_rate: 9600
    tx_pin: GPIO33
    rx_pin: GPIO21

  - id: uart_victron
    baud_rate: 19200
    rx_pin: GPIO18 

victron:
  uart_id: uart_victron
  id: victron0

jbd_bms:
  - id: bms0
    uart_id: uart_jbd

output:
  - platform: slow_pwm
    pin: GPIO15
    id: status_led
    period: 2s

Anything in the logs that might be useful for us?

unfortunately no. At least I found no way wit USB-C to grab the lines right at boot. After boot nothing ist transmitted on USBC, even if configured like:
     sdkconfig_options:
       CONFIG_ESP_CONSOLE_USB_CDC: y    
hardware log and network log is working if only one UART in use

Additional information

No response

Try disabling serial logging.

swifty99 commented 2 weeks ago

thx.

This is a good workaround.

logger:
  level: DEBUG
  baud_rate: 0

Leave this open. I think it should still work with USB logging.

alright. And it did work a few months ago.
