UART ISSUE FOR iMXRT1024 EVK

[srinadh]

1. UART clock selection only 2 ways (OSC  & PLL3)..(80MHz, 24MHz)..   Any other clock root changes or not?
2. Max Baudrate upto 5Mbps for Clock Selection was 80MHz, but in my case after 1.5 Mbps baudrate it does not support Transmission & Reception...

Hello!

Please see my answers below.

1. No, those are the available clock sources.

2. I tested 2 Mbps with my board and it worked correctly, I used lpuart_interrupt example and TeraTerm. Please check it below.

Best regards,

Felipe

5Mbps communication working or not?

[FelipeGarcia]

You should also take into consideration LPC-Link and windows FTDI driver limitations. I recommend you to measure UART signals directly using oscilloscope or logic analyze.

Yeah, I tested in between two UARTS, its working

                   Okay, Thank you....

I installed Tera Term Software, but maximum baudrate for serial port was 921600, How did you get 2000000 baudarte

[FelipeGarcia]

You can manually write it even though there is no 2 Mbps option.
