Hello,
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.
