Hello,

It sounds like you’re encountering a challenging issue with missing bytes during segmented serial communication on your Colibri iMX6 module. Let’s explore some potential solutions to help you resolve this problem:

1. Buffer Management: Verify that your serial buffer is sufficiently large to accommodate the incoming data. If the buffer is too small, it might overflow, leading to data loss. Consider increasing the buffer size in your application settings if necessary.

2. Interrupt Handling: Efficient interrupt handling is crucial in serial communication. Ensure that your interrupt service routine (ISR) is optimized to quickly process incoming data, minimizing the risk of missing bytes.

3. Read Timing: When reading data in segments, ensure your application waits for the complete segment to be available before attempting to read it. Implement checks to confirm that the expected number of bytes is present in the buffer before proceeding with the read operation.

4. Flow Control: Implementing hardware or software flow control can help manage the data flow between devices, preventing the sender from overwhelming the receiver and reducing the likelihood of data loss.

5. Testing with Continuous Read: Since reading all data at once works without issues, try to replicate this logic in your segmented read approach. This might help identify any discrepancies in your current method.

6. Debugging: Utilize debugging tools to monitor the serial data flow and identify any anomalies. This can provide insights into where the data loss is occurring.

By focusing on these areas, you should be able to pinpoint and resolve the issue with missing bytes during your segmented serial communication. If the problem persists, consider reviewing your code for any logical errors in data processing and handling.

I hope these suggestions prove helpful in addressing your issue.

RS485 serial port writing but not reading?

Colibri iMX6 DL 512MB IT running c code on Torizon Hi guys I am stumped by this… wasted 2 days already… I am able to get my RS485 port to write to a terminal program, so I know I have MOST of my settings correct anyways, for example 9600 baud 1 stop bit no parity 8 data bits no flow control and not so many days ago, I was actually able to get it to read from the serial port as well. (So this means that at least my device-tree should be in good shape… which is a relief in itself.) Sin…

Imx6ull uart DMA

Dear Community, I need to enable DMA on a uart in order to transfer a lot of bytes (a firmware) to a MCU that runs a LoRa concentrator. Using kernel 4.14.122 everything works as expected even not enabling DMA, but updating to BSP 6.2.0 with kernel 6.1.22 it seems that the serial communication hangs when I try to write more than 32 bytes over the uart. This is the reason why I try to enable DMA, and I add this to my device tree definition: + dmas = <&sdma 18 4 1>, <&sdma 19 4 2>; + dma-…
