OSError: [Errno 5] EIO : UART SPI

[Jean Bikie]

Hey
i have this error : OSError: [Errno 5] EIO
here is my code on the screen. It works well without the UART code
but when i add the uart code i have this issue.

I try to add some delay after uart initialization but always the same error.

@Jean-Bikie UART1 uses P3 and P4. P4 is also used by the SD card. So you avoid conflicts, you have to use other pins for UART.
do not use separate statements for uart creation and init, use just one, e.g.

uart=UART(1, 9600 pins=('P5', 'P6'))
