Custom UART1 TX/RX to GPIO17/GPIO16 pins

Postby moggiozzi » Thu Feb 06, 2020 12:50 pm

I configure project with:

Code: Select all

CONFIG_ESP_CONSOLE_UART_CUSTOM=y
# CONFIG_ESP_CONSOLE_UART_NONE is not set
# CONFIG_ESP_CONSOLE_UART_CUSTOM_NUM_0 is not set
CONFIG_ESP_CONSOLE_UART_CUSTOM_NUM_1=y
CONFIG_ESP_CONSOLE_UART_NUM=1
CONFIG_ESP_CONSOLE_UART_TX_GPIO=17
CONFIG_ESP_CONSOLE_UART_RX_GPIO=16
I flash chip with new compiled build/bootloader.bin & build/myapp.bin.
When i use ESP-IDF v3.2 log console output to uart1 works, but with v3.3 and 4.1 can't.
When i use bootloader.bin compiled with ESP-IDF v3.2 and myapp.bin compiled with v4.1 outputs also work.

It's Bug or I can't use GPIO17/GPIO16 pins for UART1 custom logging?

Testing ESP-IDF versions:

c:\esp32_323\esp-idf>git show
