printf while using UART in DMA mode

maybe that adi_uart_EnableDMAMode in some way is trying to write directly on UART instead of writing to console?

i need a way to have debug info on console while receiving data from serial port in DMA mode...

Hi,

Can you please confirm whether the issue got solved now. Because in the following thread

ez.analog.com/.../simple-example-on-using-uart-interrupt-to-receive-buffer-from-serial, you mentioned that your application works fine in DMA mode.

Hi,

Hi,

Could you please let us know which version of CCES you are using?

We are unable to replicate your issue. We are able to run CharEcho_Uart example project in CCES 10.0.1 version. Here printf instruction on line 87 is working fine. Please refer the attached screenshot for reference.

Can you please copy the example from BSP path and place it in other drive and try again in a new workspace.

If issue still persist means, please share your test project to us.

This would be helpful for us to assist you further.

Hi,

reported CrossCore Embedded Studio is: 2.11.0.0

I attach a couple of screenshot

Hi,

We have identified the root cause of the issue. In the driver source code, A non-recoverable error error throws because of mismatch between ADI_UART_BIDIR_INT_MEMORY_SIZE and (sizeof(ADI_UART_DEVICE)+sizeof (UART_DATA_CHANNEL)*2u) values in CCES 2.11.0. So we need to increase the ADI_UART_BIDIR_INT_MEMORY_SIZE value from 416 to 446 inside the adi_uart_bf5xx.h file. Please refer the attached image for your reference. After this change we can run the CharEcho_Uart example project in CCES 2.11.0.

We will fix this in future release of CCES.
