Hi all,
I'm setting the LPUART FIFO RX and TX sizes and it only seems to be 4 words and cannot be set to any other value. In the RM it says maximum number of receive or transmit fifo size data word can be up to 256 words.
How can I set it manually
Thanks and Regards.

Hi @Lukas_Frank ;
Justo double checked with hardware team.
The RXFIFO size is 4 data words. It is a fixed value, a hardware attribute, not configurable.

HI @Lukas_Frank :
From the reference manual , if you configure FIFO = 4, means 32 datawords.
From the driver level, 32 datawords are supported.

Hi @Lukas_Frank
Sorry,
Please refer to LPUART FIFO register
From the source code, the default RX FIFO SIZE =4, 32 data words.
You can write to the FIFO register to configure the FIFO SIZE

Hi Dear @danielchen ,
Is it possible to set it FIFO sizes more than 32 Data Word? Is 32 the maximum value of that can be set ?
Thanks and Regards.
