Since the core frequency of IMXRT1176 is relatively high, configuring it with a baud rate of 921600 should not be a problem. If there are no issues at a baud rate of 1M, then the hardware communication on the circuit board should also be fine. This is a peculiar phenome...
Problem Receiving invalid characters on host from STM32 USART transmitter Cause Invalid baudrate value is written in BRR register. Config I've programmed a F4 to use USART1 & 6 (on APB2). APB2 runs on core clock, which is 180MHz. PLL run...
