Hi there!

I have several issues while uploading RRF on my new board.

While im connectring my board with firmware to my computer, SKR reboots, like unpugs from laptop and plugs again.

When im turning on my SKR, little blue LED on WiFi module not works, and in router settings there is no board connected, in Advanced IP Scanner the same.

BTT TFT semms to be ok, but sending commands to board gives no result. Tries to move axis gives nothing, same to measure temperatures.

Im using ESP-01S as a WiFi module

Did you find any solution I am having the same issue. I am using ESP01 Wifi module. The wifi module works when connected to USB Programmer blue wifi light also glows but when I connect the ESP01 directly to the SKR 1.4 board wifi socket the module power on but the blue wifi light does not glow and hence I am unable to use it and it is also not detected by the router. Please do reply if you found a fix to it. It would really help me

Blue led is on tx line, it glows when the signal is low. But only if the board has power




The lpc176x pins for serial 3

Serial3	                 TX     RX	FUNCNUM
Default	                P0_00	P0_01	2
LPC_PINCFG_UART3_P0_25	P0_25	P0_26	3
LPC_PINCFG_UART3_P4_28	P4_28	P4_29	3

The wifi port on the skr 1.4 uses P4_28 and P4_29 so you need to enable function 3
In marlin you set LPC_PINCFG_UART3_P4_28 this is done for you in [github.com]

I don't know how you would do this on other firmwares

You also need to set a serial port to 3
