Other Parts Discussed in Thread: IWR6843
Hi, I have interfaced the IWR6843 Logger UART to Cortex M7 based board at 921600 bps baud rate.
The uart receiver in cortex m7 is configured with DMA . The buffer size is 20,000 bytes.
After sensorStart command, I am able to observe the frame data in the buffer. But I am noticing missing bytes in the buffer randomly.
In the added image. I expect to see the presence detection tlv starting from index 404.
Expected is:
buffer[404] = 11 (presence detection tlv),
buffer[408] = 12 (size of tlv)
buffer[412] = 1. (value )
But I am getting 0 values here.
What can be causing this missing bytes?
For the Cortex M7 UART.
Expected Baud Rate: 921600
Actual Baud Rate: 919117
Can this difference is baud rate cause missing bytes? Or do I need to focus somewhere else?
