https://community.nxp.com/t5/i-MX-Processors/Problem-with-UART-framing-error-on-custom-i-MX7ULP-board/m-p/1832928#M221598 <P>Hello,</P><P>I am working on a custom i.MX7ULP board that has4 UARTs, one for the serial interface for linux. I am having a problem as when I set the baud rate higher than 2400, I cannot receive more than 8 characters. It always stops at 8. I sometimes get a framing error when looking with a digital discovery analyser. This seems weird as all 3 uarts that I tested on have the same problem. It works without problem at 2400 but when I set at the default 115200, it just stops at the 8th character and cannot receive anything else. I have attached the dts files for my board as I suspect it may be an issue with the clock or something, but I am not sure. UART5 6 and 7 are the problem.</P> Thu, 21 Mar 2024 11:59:10 GMT Alexandre50000 2024-03-21T11:59:10Z https://community.nxp.com/t5/i-MX-Processors/Problem-with-UART-framing-error-on-custom-i-MX7ULP-board/m-p/1832928#M221598 <P>Hello,</P><P>I am working on a custom i.MX7ULP board that has4 UARTs, one for the serial interface for linux.
